### New Features
* _Byte Viewer_. Added support for other-than-ASCII character encodings in the ByteViewer. (GP-5689)
* _Data Types_. Added ability to merge non-conflicting structures, unions, or enums. (GP-5808, 
  Issue #2461)
* _Debugger:Agents_. Enabled synchronization between x64dbg and Ghidra. (GP-5972)
* _Debugger:Time_. Added a margin bar and new BreakpointTimelinePlugin that displays breakpoint hits 
  across the whole execution of a trace. (GP-5895)
* _DWARF_. Added support for querying `debuginfod` servers for files. (GP-5924, Issue #8407)
* _ELF_. Added markup for `.gnu.build.attributes` in ELF binaries. (GP-5929)
* _GUI_. Updated the Data Type Manager provider to remember the program archive's selected data type 
  when switching between program tabs. (GP-2370)
* _GUI_. Added a __Hide Filter__ action for Tables and Trees.  This action can be bound to the 
  `Escape` key to close the filter. (GP-6336, Issue #8771)
* _GUI_. Updated the __Find References__ action to appear in tables that have addresses. (GP-6365, 
  Issue #8899)
* _Importer:Trace_. Added a loader for Tenet trace files. (GP-6382)
* _Processors_. Added the Hexagon Language module with modified instruction syntax.  Modified syntax 
  was used to better fit Ghidra's mnemonic/operand Listing API.  This processor also introduces the 
  first use of Ghidra's Sleigh `crossbuild` feature which is used for weaving pcode for parallel 
  processor architectures such as the Hexagon. (GP-6621, Issue #1595)
* _Scripting_. Added `AddVfunctionCallRefScript`, which, if the cursor is on a vftable->function 
  token in the Decompiler, will create a CALL reference to the associated function in the Listing, 
  if it can be determined. (GP-6693)
* _Search_. Added the ability to scan using the results from one progam rebased on another. (GP-6260)

### Improvements
* _Analysis_. More Swift type metadata has been marked up. (GP-6281)
* _Analysis_. Improved Golang analyzer to handle some obfuscation techniques. (GP-6291, Issue #8804)

* _Build_. Ghidra can now be built on Windows on ARM (requires Gradle 9.2 or later). (GP-6126)
* _Data Types_. Change was made which consistently allows duplicate component/field naming within 
  Structure/Union datatypes.  When editing a name within the GUI, the user will be warned and must 
  confirm use of a duplicate name. (GP-3564, Issue #5249)
* _Data Types_. A datatype which gets removed will no longer attempt to update itself as a result of 
  dependency changes.  This may reduce the number of superfluous listener callbacks and events that 
  occur during the removal process. (GP-5882)
* _Debugger_. Added parameter for custom arguments to gdb/lldb. (GP-6112, Issue #8565)

  statements from the Decompiler window. (GP-5922, Issue #4438, #8196, #8726)
* _Decompiler_. Added a Decompiler action to toggle the __Disable printing of type casts__ option. 
  (GP-6199, Issue #7452)
* _Decompiler_. Added setter methods to the DecompilerOptions class.  These can be used by script 
  writers to control the Decompiler's behavior. (GP-6266, Issue #8812)

  (GP-6108, Issue #8609)
* _Demangler_. Updated the Gnu Demangler v2.24 to support the `static` modifier for functions. (GP-6394)
* _Emulator_. Introduced a default `LOCK` userop definition for x86, and a default 
  `ExclusiveMonitorPass` for ARM, as well as for other userops and processors. (GP-4241, Issue #6089, 
  #7495)
* _Emulator:JIT_. Optimized handling of multi-precision integers; i.e., varnodes of size greater 
  than 8 bytes. (GP-5980)
* _Function Compare_. Fixed the Function Comparison provider so that it saves changes made to the 
  Listing View fields.  The provider will now also remember the last view tab selected. (GP-6016)
* _GUI_. Added a Data Type Manager action to search for enums by value. (GP-1914)
* _GUI_. Added popup menu items __Close Other__, __Close Tabs to the Right__, and 
  __Close Tabs to the Left__ to docking window tabs. (GP-4961)
* _GUI_. Added namespace chooser to Add/Edit Label Dialog. (GP-5806, Issue #8263)
* _GUI_. Changed the Log Viewer to a window instead of a dialog so that it can be maximized. 
  (GP-6044)
* _GUI_. Added a __Find All__ button in the Find Dialog used in many component providers. (GP-6076)
* _GUI_. Updated the Listing Snapshots to include the Flow Arrows, Margin Markers, and Overview 
  Markers. (GP-6085, Issue #8601)
* _GUI_. Added an action to the Symbol Tree to allow users to toggle outgoing navigation events. 
  (GP-6101, Issue #8618)

  on the source from where the memory addresses originated. (GP-6147, Issue #8548)
* _GUI_. Added a `modify()` method to the Annotation class so clients can perform their own 
  annotation transformations. (GP-6451, Issue #8928)
* _Importer_. The `ElfLoader` can now recognize Swift and golang binaries. (GP-3960, Issue #8795)
* _Importer_. The `NeLoader` can now load binaries that used Phar Lap’s 286/DOS-Extender. (GP-6537, 
  Issue #1905, #2493)
* _Importer:PE_. The PE loader now sets up thunk functions for export forwarders. (GP-5900)
* _Importer:PE_. The PE Dynamic Value Relocation Table (DVRT) is now parsed and marked up. (GP-6502)
* _Jython_. Jython support is now delivered as a Ghidra Extension, which means an extra step is 
  required to install it. If Jython is required, the user should simply go to 
  __File -> Install Extensions__ in the Ghidra Front End GUI and check __Jython__. The user must 
  restart Ghidra to complete the enablement of Jython. (GP-6754)
* _Languages_. More Swift type metadata has been parsed and marked up. (GP-6137, Issue #8607)
* _Listing_. Added a feature to allow function bodies to be closed in the Listing. (GP-5987)
* _Listing_. Changed offcut string references to use the existing non-default label at the string 
  beginning instead of the default name created from the string's offcut location. If no label is 
  defined, the default offcut string naming scheme is used (`s_[substring]` instead of 
  `[label name]+offset`). (GP-6345, Issue #8882)
* _Multi-User_. Improved Ghidra Server serialization filters and added serialization filters to 
  client-side Ghidra applications.  We may have missed something in our testing so let us know if 
  you encounter an `InvalidClassException`.  The log will identify a class which fails to pass the 
  filter rules. (GP-6719)
* _Processors_. Corrected behavior of ARM thumb `branchWritePC` macro. (GP-6333, Issue #8585)
* _Processors_. Added `maximumInstructionLength` language property in support of `inst_next2` use. 
  (GP-6613, Issue #8941)
* _Processors_. Corrected operand order for MIPS162e `movn` and `movz` instructions. (GP-6766)
* _Project_. Expanded on the set of allowed special characters for a local Ghidra project path name 
  to include the following: `'.'`, `'-'`, `'='`, `'@'`, `' '`, `'_'`, `'('`, `')'`, `'['`, `']'`, and 
  `'~'`. (GP-6681)
* _PyGhidra_. PyGhidra will now, by default, restore `sys.modules` to its prior state after a 
  PyGhidra script is run (or the interactive interpreter is reset) so the next time a script is run, 
  it freshly loads all of its imported modules again. This default behavior can be disabled by 
  setting the `pyghidra.sys.modules.restore.disable` Java system property to true, which can be done in 
  the `support/launch.properties` file. (GP-6288)
* _Scripting_. Made some improvements to the `RecoverClassesFromRTTIScript` for GCC programs. (GP-6670)
* _Search_. Fixed an issue where some matches were not found when doing a regular expression search 
  using the regex _lookbehind_ clause. (GP-6070)
* _Search_. Updated MemoryBytePatternSearcher to correctly handle mapped blocks. (GP-6308)
* _Sleigh_. Fixed the Sleigh `goto` statement to accept 64-bit literals. Added range-checking for 
  literals in Sleigh compiler. This fixes an Emulator issue where edits to the `pc` register were 
  truncated to 32 bits. (GP-6328, Issue #8875)
* _Symbol Table_. In the Symbol Table's __Symbol References__ table, the user can now select 
  multiple refs in the refs table to delete more than one reference at a time.  There is also a new 
  action in the Symbol Table popup action to allow the user to delete all references to a symbol, 
  found under __References -> Delete All__.  Finally, there is a new __Make Selection__ action in 
  the popup menu of the References Table to select, in the Listing, all references to a symbol. (GP-6430)
* _Testing_. Upgraded jacoco to 0.8.14. (GP-6504)
* _Version Tracking_. Improved Version Tracking so that when applying `thiscall` function signatures, 
  the source's class structure is copied to the destination program, if appropriate, given the 
  chosen apply options. (GP-5709, Issue #8127)
* _Version Tracking_. Updated Version Tracking to allow replacing of existing function label 
  namespaces. (GP-5996)

### Bugs
* _Analysis_. Added support for Windows DLLs generated by Golang. (GP-6325)
* _Analysis_. Corrected `AutoAnalysisManager.removeCancelledListenter()` to call `removeCancelledListener()` 
  instead of incorrectly calling `addCancelledListener()`.  This addresses a potential memory leak 
  within Ghidra. (GP-6789)

  selected Program datatypes.  A normal copy or datatype drag-n-drop may still be used between all 
  datatype archives. (GP-6362)
* _Data Types_. Corrected Structure Editor __Unpackage Component__ action which was misplacing 
  components. (GP-6574, Issue #9041)
* _Data Types_. Corrected Structure `insertAtOffset` behavior when inserting at an offset which 
  precedes a zero-length component. (GP-6576)
* _Data Types_. Corrected upgrade failure which can occur for Project Data Type Archives. (GP-6649)

* _GUI_. Fixed key bindings that use the `Alt` key so that the right `Alt` key works in addition to 
  the left `Alt` key.  This is now an option that can be disabled for users that prefer to keep the 
  right `Alt` key independent of the left `Alt` key. (GP-6450, Issue #8205, #8969)

  default or user-specified `script.log` file. (GP-6532)
* _Memory_. Corrected various issues related to improper use of Addresses from one program in 
  another program's AddressMap. (GP-6150)
* _Multi-User_. Corrected potential security concern with Ghidra Server PKI Authentication.  If 
  using PKI Authentication mode (`-a2`) for the server install, the user should upgrade the server.  
  See reported Ghidra GitHub Pull Request #9109 for more details. (GP-6678, Issue #9109)
* _Multi-User_. Added Ghidra Server `-ipAlt` option to address self-signed certificate issues

* _Project_. Eliminated the maximum 60-character length naming restriction imposed on various Ghidra 
  elements, including: project name, repository name,  project archive filename, and Ghidra tool 
  config names.  Efforts have been made to allow for the use of foreign-language-naming of these 
  elements.  Support for Ghidra projects stored on a Windows UNC shared drive has also been added. 
  (GP-6402, Issue #8731)
* _Search_. Fixed __Context__-column-sorting in the __Find References__ results table. (GP-6421,

### Notable API Changes
* _API_. (GP-6039) Revised `ProgramUtilities.parseAddress(Program, String)` to handle the parsing of 
  external addresses (e.g., `EXTERNAL:000000100`).  Support for memory block style addresses has been 
  eliminated for this method (e.g., `<blockName>:<offsetWithinAddressSpace>`).  Memory block style 
  addresses should not be used.
* _Basic Infrastructure_. (GP-6370) `GenericXMLOutputter` is now instantiated with a static 
  `getInstance()` method rather than a constructor.
* _Byte Viewer_. (GP-5689) ByteViewer's `DataFormatModel.replaceValue()` has been moved to the new 
  `MutableDataFormatModel` interface, and `DataFormatModel.isEditable()` has been removed.  
  `DataFormatModel.validateBytesPerLine()` has been replaced with `validateByteViewerConfigOptions()`. 
  `DataFormatModel.setByteViewerConfigOptions()` has been added and `(get/set)GroupSize()` has been 
  removed.

  register overlay spaces, where applicable.
* _Debugger:Emulator_. (GP-6159) Removed `PcodeUseropDefinition.execute(PcodeExecutor, PcodeUseropLibrary, Varnode, List)` 
  in favor of one taking `PcodeOp` as well.
* _Emulator_. (GP-4241) Converted each now-deprecated `XxxEmulateInstructionStateModifer` to a 
  `XxxPcodeUseropLibraryFactory`.
* _Emulator_. (GP-6158) `AnnotatedPcodeUseropLibrary` now allows static methods to be marked 
  `@PcodeUserop`. Both interpretation and JIT emulators can invoke them.
* _Emulator_. (GP-6234) Deprecated `EmulatorHelper` and related.
* _GUI_. (GP-6451) Added a `modify()` method to the Annotation class so clients can perform their own 
  annotation transformations.
* _Project_. (GP-6402) Overhauled GhidraURL utility class which now uses URI to generate URLs to 
  ensure that proper encoding and decoding is performed.  Added `GhidaURL.resolve` method which 
  simplifies creating a new Ghidra URL derived from another Ghidra URL to the same project or 
  repository.
* _Search_. (GP-6261) Various classes related to searching memory for byte patterns have been 
  changed to use generics to make them generally more useful.
* _Search_. (GP-6309) `SequenceSearchState` is renamed to `BulkPatternSearcher` and its API has changed. 
  Also, it and related classes have been changed to use generics and support different kinds of 
  patterns.

# Ghidra 12.0.4 Change History (March 2026)

### Improvements
* _Analysis_. Updated the RTTI Analyzer to better handle the case where class names cannot be demangled correctly. Previously, class members would end up in global namespace.

* _Multi-User_. Revised Ghidra Server self-signed certificate generation to include all associated FQDNs and IP addresses as subject alternative names.  This will address the forced hostname check imposed with the release of JDK 21.0.10.  To benefit from this change the Ghidra Server will need to be upgraded to this release.  A client-side workaround is to set the following JVM property within `support/launch.properties` by adding the line: `VMARGS=-Djdk.rmi.ssl.client.enableEndpointIdentification=false`. (GP-6426, Issue #8940)
* _Processors_. Fixed bug in AARCH64 `sha1h` instruction to shift instead of rotate bits. (GP-4501, Issue #6398)

* _Debugger:Emulator_. The emulator will now use the nearest snapshot, allowing it to resume more quickly after restarting Ghidra. (GP-6236, Issue #8767)
* _Debugger:Time_. Invalidated rows in Time Panel are now displayed in gray. This is to indicate that navigating to it will require re-emulation. (GP-6244)
* _Decompiler_. Added abstract interpretation via the Software and System Verification (SSV) group @ Università Ca' Foscari's Library for Static Analysis (LiSA).  This capability was meant for the previous release, as noted in the 12.0 Change History. (GP-6225)

### Bugs
* _Assembler_. Fixed issue preventing some PPC VLE instructions from assembling. (GP-6109, Issue #8624)
* _Assembler_. Fixed an issue with Assembler corrupting instructions that followed, especially when ISA mode is involved. (GP-6295, Issue #8826)
* _Debugger:Emulator_. Fixed some crash cases in Taint emulator regarding mismatched op sizes. (GP-6287)

(GP-6229) The emulation support method for CALLOTHER `OpBehaviorOther.evaluate` implementations has dropped the first input varnode which was used to identify the `OpBehaviorOther` implementation.  Only the inputs which are specified by the arguments passed to the named pcodeop within the slapsec are now passed to this method.  NOTE: The actual API change occurred within Ghidra 11.3 with GP-4643 change.

# Ghidra 12.0 Change History (December 2025)

### New Features
* _Data Types_. Added `RGB16` and `RGB32` Color primitive datatypes which have been implemented as unsigned integer types and will render a color patch for Data within the Listing.  These default, respectively, to `RGB_565` and `ARGB_8888` encodings but can adopt a different RGB Encoding through the use of a Typedef and a default Setting. (GP-4310, Issue #6191)
* _Decompiler_. Implemented low-pcode-based abstract interpretation via the Università Ca’ Foscari's Library for Static Analysis (LiSA). (GP-5566)
* _Emulator_. Added an experimental Z3 Symbolic emulator with a summarization GUI. This feature is distributed as an installable extension. (GP-5727)
* _FileSystems_. Add support for zstd compression in GFileSystem via user-provided zstd or 7-Zip command line tools. (GP-5842)
* _Graphing_. Added a Function Graph tab to the Function Comparison widget.   This allows users to see two functions side-by-side in Function Graph views, such as when viewing BSim functions. (GP-3648, Issue #1154)
* _Graphing_. Created a new prototype __Data Graph__ graphing feature with nodes that display data structures and values and edges that link one data structure to another via a pointer reference. (GP-5481)
* _GUI_. Updated the Xrefs Table to allow the user to delete references to the current location. (GP-2140, Issue #4317)
* _GUI_. Added a shared project repository connection status indicator to the root node of the project data tree.   A popup menu action was also added to the root node allowing the connection to be established when in a disconnected state. (GP-5333)
* _GUI_. Added ability to toggle the displaying of function variables (parameters and locals) that are normally displayed just below the function signature. The variables display can be turned on/off globally or individually per function. (GP-5886, Issue #8385)
* _Importer_. Created an importer for the Decompiler debug format which is produced by the Decompiler. (GP-3947)
* _Importer_. Added an option to mirror the local filesystem when importing programs and their libraries. Programs and libraries that exist on the local filesystem as symbolic links will have both their corresponding link file and resolved program file mirrored in the project. (GP-5343, Issue #7430)
* _Importer_. Added a new loader for HP-UX PA-RISC __System Object Module__ (SOM) binaries. (GP-5942)
* _Processors_. Added support for the NDS32 Processor. (GP-6007, Issue #1778)
* _Project_. Added expanded support for project link-files with the introduction of internal project folder and file links.  The links behave similar to Linux symbolic links and allow a single folder or file to be referenced by alternative project paths.   The GUI Project Tree and related project file chooser have also been improved with the ability to expand folder-links like folders (subject to filter restrictions at the API level).  The main Project Tree will continue to rely on project views for following external folder-links.  Some of the project tree's recursive traversal actions do not follow folder-links (e.g., Expand All).  NOTE: Although Ghidra permits files and folders to have the same name, this should be avoided when utilizing link-files or Ghidra URLs due to the path ambiguity it can cause.  This change also introduces a new file storage format which can create issues within a project if opened with an older version of Ghidra.  While this version remains compatible with older Ghidra Server versions, adding link files to a repository will require a Ghidra Server upgrade to the latest version. (GP-3551)

### Improvements
* _Accessibility_. Fixed tooltips in the Symbol Tree to not read HTML markup to screen readers. (GP-5741, Issue #8228)

* _Data Types_. Added utility methods to the `DataTypeQueryService` for clients to have more flexibility in how they retrieve data types. (GP-5694, Issue #8157)
* _Debugger:Agents_. Upgraded to `protobuf-java 4.31.0` and `protobuf 6.31.0` for Python. (GP-5456)
* _Debugger:Agents_. Improved debug-connection failure-detection when the back-end terminates early. (GP-5700)
* _Debugger:Emulator_. Added Help for `PcodeStepperPlugin`. (GP-5772)
* _Debugger:Emulator_. Fixed an issue with emulation when the program has block/sections with brackets in the name. (GP-5897, Issue #8398)
* _Debugger:LLDB_. Fixed variable name typos in the `lldbsetuputils.ps1` script. (GP-5973, Issue #8498)
* _Debugger:Trace_. Removed legacy mode from the Trace database. (GP-5194)

* _DWARF_. Added code for parsing DWARF `.debug_macro` sections and example script, `DWARFMacroScript`. (GP-5792)
* _DWARF_. Add support for specifying the charset of DWARF debug strings. (GP-5871, Issue #8346)
* _DWARF_. The DWARF analyzer can now create enums from macro information recorded in DWARF debug data (DWARF v5 only). (GP-5984)
* _ELF_. Added partial support for AARCH64 ELF loading of object modules with GOT allocation capability.  Added support for the following relocation types which rely on this revised relocation handler capability: `R_AARCH64_ADR_GOT_PAGE`, `R_AARCH64_P32_ADR_GOT_PAGE`, `R_AARCH64_P32_LD32_GOT_LO12_NC`, and `R_AARCH64_LD64_GOT_LO12_NC`. (GP-5815, Issue #8253)
* _Emulator_. Refactored the p-code emulator to use composition instead of inheritance for UI integration. This should simplify development of extended emulators and permit easier integration of those emulators with the UI. (GP-5879)
* _Emulator:JIT_. Added support for multi-precision integers (varnodes of size 9 or greater) to the JIT-accelerated p-code emulator. (GP-5214)
* _Exporter_. Updated the IDA Pro exporter to work with IDA Pro 9.x. (GP-5873, Issue #7392)

* _GUI_. Updated the Structure Editor's __Find Uses of__ action to work on fields with no name or data type. (GP-5711, Issue #8171)
* _GUI_. Added modes to the drop-down text fields to control how matches are found.  Choices will now typically include __Starts With__ and __Contains__ modes. (GP-5720, Issue #4725, #8203)
* _GUI_. Update the Data Type Manager's __Collapse__ toolbar action to stop any post-filter state-restoring. (GP-5761, Issue #8244)
* _GUI_. Updated dialogs wth combo boxes to have consistent behavior when pressing the `Enter` key. (GP-5769, Issue #8280)
* _GUI_. Updated the Ghidra File Chooser to not lock the UI for folders that contain many files. (GP-5807, Issue #4725, #8284)
* _GUI_. Reduced some excessive Symbol Tree updates seen while performing auto-analysis. (GP-5826)
* _GUI_. Fixed bug in Memory Search where some GUI options were not initialized correctly to the last-used options. (GP-5883)
* _GUI_. Updated the __Next Instruction__ action to jump to the function entry point when the action is invoked from the function signature. (GP-5885, Issue #8385)
* _GUI_. Added full data type path to Decompiler and Listing hovers. (GP-5913)
* _GUI_. Created new theme value for the Decompiler's middle-mouse highlight color so that the Listing and Decompiler colors may change independently. (GP-5947)
* _GUI_. Added convenience methods to `TableColumnDescriptor` to create simple columns using only a name, column type, and a function to map from the row object to the column object. (GP-5963, Issue #7346)

* _GUI_. Added accelerator mnemonics to the Memory Search dialog to help reduce manual navigation issues. (GP-5979, Issue #8264)
* _Headless_. The user can now specify headless loader options independently of what loader is being used. The headless importer will ignore loader options that are unsupported by the active loader. (GP-5545)
* _Help_. Added Processor, Language, and Compiler specification file names to __About Program__ dialog. (GP-5716, Issue #8163)
* _Importer:COFF_. Added support for importing big-endian COFF binaries. (GP-5645, Issue #1398, #8042)
* _Importer:PE_. The PeLoader no longer fails to import if a Data Directory does not parse successfully. (GP-4881, Issue #6864)

* _MachineLearning_. Updated __RandomForestFunctionFinderPlugin__ with improved model training performance, the ability to apply a model to a program selection, and the addition of disassembly to the similar-starts table. (GP-4400)
* _PDB_. Modified handling of PDB thunks so that for when Ghidra does not consider the function to be a thunk, which would normally cause the thunk to get the same signature as the thunked function, the Demangler is enabled to set the proper function signature and name.  This affects C++-related functions, for example, such as vtordisps and adjustors. (GP-5713)
* _Processors_. Added initial implementation of ARM Neon `VLD`/`VSTn` instructions. (GP-5853)
* _Processors_. Added support for MIPS16e2 instructions. (GP-5902, Issue #8406)
* _Processors_. Refactored RISCV context and moved CSR registers into a CSR memory space to support custom instructions and RISCV variants.  Also added sample RISCV variant Andestar. (GP-5975)
* _Processors_. Corrected AArch64 `fmadd` operand semantics ordering. (GP-6121, Issue #8454, #8625)
* _ProgramDB_. Improved performance of Symbol Table and its storage of `ExternalLocation` data. (GP-5498)
* _Scripting_. Condensed the script categories into a better-organized subset of categories. (GP-3952)
* _Scripting_. Python scripts that do not declare a `@runtime` metadata comment now default to PyGhidra instead of Jython. Jython scripts will need to include the "`# @runtime Jython`" script header in order to continue running within the Jython environment. (GP-5415, Issue #7856)
* _Scripting_. Released PyGhidra 3.0.0. (GP-5637, Issue #6914, #6915)

* _DWARF_. Fixed issue with importing 64-bit DWARF when subsections of the DWARF line info were marked as 32-bit. (GP-5931)
* _FID_. Added a temporary fix to identify the `security_check_cookie()` function in VS2022 binaries.  If the function is not identified, the return type is incorrectly recovered by the Decompiler. (GP-5998, Issue #2743)
* _Function_. Fixed thunk detection and thunk address calculation for thunks with an internal call/branch to the next instruction in order to load the current PC into an LR register. (GP-6072)
* _GUI_. Updated the Plate Comment field to render annotations' display text instead of raw annotation text. (GP-3756)
* _GUI_. Fixed potential deadlock in Ghidra tables that use the __Code Unit__ table column. (GP-5724, Issue #8208)
* _GUI_. Fixed bug that caused an incorrect tab to be selected when closing docked component provider tabs via the __x__ button. (GP-5821, Issue #8303)
* _GUI_. Fixed the Decompiler's __Edit Data Type__ action to correctly scroll the structure field being edited. (GP-6045, Issue #8522)
* _Languages_. Fixed issue with importing 32-bit RUST binaries for x86 Windows- and Unix-based systems. (GP-4711, Issue #6042)
* _Navigation_. Changed __Next Function__ / __Previous Function__ actions to skip functions that are not in memory. This prevents the actions from becoming _stuck_ until the user manually moves to an new address past the non-memory function. (GP-5712)
* _PDB_. Fixed an issue where the function arguments list record was a NOTYPE, which caused the analyzer to terminate. (GP-6010)
* _Processors_. Fixed ARM `vmvn` instruction semantics. (GP-4650, Issue #6544)
* _Processors_. Fixed SuperH4 `FSCA` instruction destination operand and FPU-register ABI-ordering for little-endian. (GP-5759, Issue #8192)
* _Processors_. Corrected 80251 `ANL` instruction variant disassembling as `ADD`. (GP-5903, Issue #8393)
* _Processors_. Fixed 80251 `ANL Areg,Data` source-mode disassembly bug. (GP-5904, Issue #8394)

* _Processors_. Fixed several issues including ARM `cpy` instruction setting the PC, incorrect function start pattern, and spurious references when saving the PC at function entry. (GP-6079)
* _Project_. Corrected issues related to failed attempts at removal of multiple folders from project tree via a selection. (GP-5907)
* _Project_. Improved project tree change listener to handle link status updates when such links reference non-visited regions of the project tree. (GP-5908)
* _Scripting_. Fixed the `GhidraScript.writer` member variable to properly get used in the various `GhidraScript.print*()` methods. (GP-5737)
* _Scripting_. Updated vxWorks symbol-table-finding script to better filter out runs of pointers when trying to locate the table.  Also, deleted old scripts and fixed demangling and labeling issues. (GP-5969, Issue #8024)
* _Scripting_. Jython scripts invoked via `runScript()` now have their local variables properly reset to a fresh state. (GP-5981)

* _Scripting_. Fixed a bug that prevented PyGhidra from redirecting output from  `print()` and `sys.stdout.write()` to the Ghidra GUI scripting console. (GP-6021, Issue #8524)
* _Scripting_. Fixed a bug in the the PyGhidra headless analyzer that resulted in the wrong exception being thrown when a script tries to import a module that isn't found. (GP-6132, Issue #8610)
* _Symbol Tree_. Updated the Symbol Tree to respond to external program path changes. (GP-5793)
* _Symbol Tree_. Fixed a bug where opening a folder in the Symbol Tree caused navigation to occur in the Listing. (GP-5914)

### Notable API Changes
* _API_. (GP-5600) The `AutoImporter` class has been deprecated. Use the new `ProgramLoader.Builder` class instead. The returned `Loaded` class should now be managed with a _try-with-resources_ pattern.  If a `DomainObject` is extracted from a `Loaded` object, it must be released independly of closing the `Loaded` object.
* _Assembler_. (GP-5800) Deleted `DbgTimer`.
* _Data Types_. (GP-5694) Deprecated `DataTypeQueryService.getDataType()`.   This method has been replaced by `promptForDataType()`.
* _Debugger:Agents_. (GP-5700) Launcher scripts `GHIDRA_HOME` now points to `<ghidra-install>/Ghidra`. `MODULE_HOME` now points to containing module root. Can request `MODULE_Xxx_HOME` pointing to module `Xxx` root by placing `@depends Xxx` in header.
* _Debugger:Trace_. (GP-5194) Objects mode is now the normal mode for Trace databases. The legacy mode has been removed. As a result, the root object must be created early, since other managers require it. Merged methods from `TraceObjectX` interfaces into `TraceX` (only those derived from `TraceObjectInterface`). To avoid confusion, renamed `TraceMethod` (in Java TraceRmi Client) to `TraceRmiMethod`. Renamed `TraceBreakpoint` to `TraceBreakpointLocation`. Added `TraceBreakpointSpecification`, `TraceBreakpointCommon`. Deleted `TraceAddressSpace` in favor of `AddressSpace`. Added `DebuggerCoordinates.isRegisterSpace()`. Space-based managers, e.g., `TraceMemoryManager`, no longer have special tables for register spaces. They all use the overlay-named-after-register-container convention. Added `TraceBaseCodeUnitsView.get(platform,snap,register,forward)`. Memory region management is moved from `TraceMemoryOperations` to `TraceMemoryManager`. Removed experimental and incomplete `TraceProgramView.getViewRegisters()` method and related. Removed `thread` parameter from `TraceLabelSymbolView.add/create`. Added variant of `TraceLabelSymbolView.add/create` that takes `platform(optional),thread,register` (and similar with getters in `TraceSymbolWithLocationView`). Added methods to `DefaultSchemaContext` and related builders to more easily build a context derived from an existing one. Added `TraceObjectManager.requireRootSchema()`. Added `TraceRegisterUtils.getRegisterContainer`, `getRegisterAddressSpace`, `getThread`, and `getFrameLevel`.
* _Debugger:Trace_. (GP-5926) Added `TraceReference.getToRange`. Added `TraceReferenceOperations.addMemoryReference(...AddressRange toRange...)`. Added `TraceReferenceOperations.getReference(...AddressRange toRange...)`. Added `TraceReferenceOperations.getReferencesToRange(...order)`.
* _Debugger:Watches_. (GP-5795) Added `WatchRow.get/setComment`.
* _Emulator_. (GP-5727) Added `SymZ3PcodeEmulator` and related.
* _Emulator_. (GP-5864) Added `EmulatorUtilities`.
* _Emulator_. (GP-5879) <B>Primary changes</B>: Added `PcodeEmulationCallbacks`, `PcodeStateCallbacks`, `ComposedPcodeEmulationCallbacks`. Added `Writer` and `TraceWriter`. Added `PieceHandler` and implementations for `byte[]`, `TaintVec`, and `SymValueZ3`. Added `TraceEmulationIntegration`. Added `DebuggerEmulationIntegration`. Deleted `TracePcodeMachine`, `DebuggerPcodeMachine` and all implementations. `PcodeMachine` is used with a `Writer`/callbacks instead. Deleted `TracePcodeExecutorStatePiece` and all implementations. `PcodeExecutorStatePiece` is used with callbacks instead. Deleted `AbstractDebuggerPcodeEmulatorFactory`. `EmulatorFactory` is used instead. Deleted `TraceEmulatorPartsFactory`, `DebuggerEmulatorPartsFactory` and all implementations. `EmulatorPartsFactory` is used instead. Changed constructor of `AbstractPcodeMachine` to require callbacks. Changed constructor of `AbstractLongOffsetPcodeExecutorStatePiece` and derivatives to require callbacks. Changed signature of `PcodeExecutorStatePiece.fork` to require callbacks. Changed signature of `EmulatorFactory.create` to accept a `Writer`. Changed signatures of several methods in `EmulatorPartsFactory` to accept callbacks. 
<BR><B>Secondary changes</B>: Added `PcodeTraceAccess.deriveForWrite(snap)`. Added `PcodeTracePropertyAccess.getEntry/put`. The `put` method is also modified to clear if `value` is null. Added `PcodeArithmetic.getDomain`. Added `PcodeExecutorStatePiece.streamPieces`. Added `AbstractPcodeExecutorState`. Added `PcodeExecutorStatePiece.get/setVarInternal`. Added `PcodeExecutorStatePiece.getNextEntryInternal`. Renamed `DebuggerPcodeEmulatorFactory` to `EmulatorFactory`. Changed signature of `PcodeDebuggerMemoryAccess.readFromStaticImages`. Several changes to `AbstractLongOffsetPcodeExecutorStatePiece` and its derivatives. See stock implementations for updates. In particular, removed all notion of "backing" including the type parameter `B`.
* _Emulator:JIT_. (GP-5214) Added `PcodeUseropDefinition.getOutputType()`. `AnnotatedPcodeUseropLibrary` allows `@PcodUserop` methods to take `int[]` parameters, including for the `@OpOutput` parameter.
* _FileSystems_. (GP-5825) Removed GFilesystem `LocalFileSystemSub` class.
* _FileSystems_. (GP-5842) Removed `throws IOException` from `ByteProvider.length()` method.
* _Graphing_. (GP-3648) The `CodeComparisonPanel` extension point has been renamed to `CodeComparisonViewer`.   Any clients subclassing `CodeComparisonPanel` will need to rename their parent class reference and also rename their extension to end with `CodeComparisonView` instead of `CodeComparisonPanel`.
* _GUI_. (GP-5769) Removed the `GhidraComboBox.setEnterKeyForwarding(boolean)` method.  Any clients calling this method with a value of `true` may simply delete the call to maintain the previous behavior,  Any clients calling this with a value of `false` will need to change how the combo box responds to `Enter` key presses in a way that preserves effect of not passing the `Enter` key press up to the parent container.
* _GUI_. (GP-5963) Added convenience methods to `TableColumnDescriptor` to create simple columns using only a name, column type, and a function to map from the row object to the column object.
* _Importer_. (GP-3947) Added `XmlElement.isStart(String string)`, which checks that the element is a starting element and also that its name matches the passed string.
* _Importer_. (GP-5343) The `Loader.load()` and `Loader.loadInto()` interface definitions have been simplified to take in a new `ImporterSettings` record.  The `Loader.getDefaultOptions()` definition has also been changed to accept a new `mirrorFsLayout` parameter.  These changes trickle down the loader class hierarchy, so all 3rd party loaders will need to be updated to work with Ghidra 12.0.
* _ProgramDB_. (GP-5498) Revised `ExternalManager` interface including removal of previously deprecated methods which have new method names.  The `getExternalLocations` now returns a `Set` of locations instead of a `List`.
* _ProgramDB_. (GP-5990) Eliminated the various forms of the `Listing.getCompositeData` method and associated map table from the Program database.  These methods were never used within Ghidra and were found to be the source of unnecessary overhead.For infrequent needs, a defined-data iterator can be used to identify locations where composites exist.  In addition, the following related Program and Trace events were eliminated: `ProgramEvent.COMPOSITE_ADDED`, `ProgramEvent.COMPOSITE_REMOVED`
`ChangeManager.DOCR_COMPOSITE_ADDED`, 
`ChangeManager.DOCR_COMPOSITE_REMOVED`,`ProgramEvent.COMPOSITE_ADDED`, `ProgramEvent.COMPOSITE_ADDED`.
* _Project_. (GP-3551) Made significant changes to `ProjectDataUtils` in support of folder and file links.  This utility's static methods should be used in place of directly instantiating `DomainFileIterator` or `DomainFolderIterator`.   Significant changes have been made to `ProjectData` storage and interface to accommodate expanded link-file support.  The `getFile` and `getFolder` methods have been overloaded with an optional filter to control treatment of such link-files where the pre-existing method forms will ignore external links.  Extensive changes have also been made to the Project Data Tree component which now has the ability to render and follow folder and file links.  Since a folder link exists as a `DomainFile`, and all link-files rely on unique content-types, additional logic is needed to follow such links.  `LinkFileInfo` can be obtained from a `DomainFile` although the use of `ProjectData` and `ProjectDataUtils` will simplify the use of link-files.
* _Scripting_. (GP-5737) Added a `GhidraScript.set()` method that takes a new `ScriptControls` object which provides more control over how scripts write to stdout and stderr.
* _Scripting_. (GP-5961) Deprecated `pyghidra.open_program` and `pyghidra.run_script`.

* _Importer:PE_. Fixed a regression that caused bad functions to be created in the middle of good functions in PE files with chained `IMAGE_FUNCTION_RUNTIME_ENTRY`s, and prevented some PE binaries from importing. (GP-5916, Issue #8414)
* _Importer:PE_. The `IMAGE_RESOURCE_DIRECTORY_ENTRY` data type is now correctly defined as a structure instead of a union. (GP-5935, Issue #8446)
* _PDB_. Fixed structure member issue, broken with 11.4 release, that could cause improper structure layout and Decompiler low-level errors. (GP-5928)
* _Processors_. Added additional SPE and APU instructions to e500 PowerPC variant. (GP-5945)

* _Languages_. (GP-5752) Removed the second parameter of `InstructionPrototype.getSeparator()`, as it was unused.

# Ghidra 11.4 Change History (June 2025)

### New Features
* _Basic Infrastructure_. Implemented Dockerized Ghidra. See `docker/README.md` for information about how to build the docker image for Ghidra and how to run the Ghidra container. This feature includes `headless`, `ghidra-server`, `bsim-server`, `bsim`, `pyghidra`, and `gui` entrypoints. (GP-3579)

* _Debugger:Time_. Added actions to __Debugger__ menu to set the display radix for snapshot keys and time schedules. (GP-5523)
* _Importer_. Provided new loader for the `Unix A.out` binary file format. (GP-3182, Issue #4943, #5004)
* _Search_. Added new Search-and-Replace feature. This feature make it easy to globally rename many different types of program elements and update related comments. (GP-5310)

### Improvements
* _Accessibility_. Provided accessible names for most dialog components. (GP-4555)
* _Analysis_. Added support for Golang closures and generic functions.  Added support for applying function signatures to core Golang library functions that were captured and stored in API snapshot files. (GP-2432, Issue #6367)
* _Analysis_. Improved speed of constant reference analysis and stack analysis. (GP-4512)
* _Analysis_. Improved decompilation of Golang functions by eliminating compiler-generated boilerplate calls to internal garbage-collection functions. (GP-5373, Issue #7484)
* _Analysis_. Updated the IMAGE_RUNTIME_FUNCTION_ENTRY structure for x86 programs to change the EndAddress type from an ImageBaseOffset32 to a DWORD.  This helps prevent references and code from being incorrectly created at the address after each listed function. (GP-5430)
* _Analysis_. Improved how Golang interface methods are modeled. (GP-5455, Issue #7529)
* _Analysis_. The __Rust String Analyzer__ no longer clears and converts strings defined in the header to character arrays. (GP-5643, Issue #8019)
* _API_. Updated some Decompiler locations to better navigate the Listing. (GP-5453, Issue #7518)
* _Basic Infrastructure_. Upgraded 3rd party jars for Bouncy Castle, Apache Commons Compress, Apache Commons Lang3, Apache Commons IO, and JUnit. (GP-5631)
* _BSim_. The BSim `support/make-postgres.sh` script now runs on linux_arm_64 and mac_arm_64 platforms. (GP-5282, Issue #7287)
* _BSim_. Made BSim installed by default. (GP-5435)
* _BSim_. Added checks to `AddProgramToH2BSimDatabaseScript` to prevent the generation of signatures when a program has unsaved changes or no functions. (GP-5562, Issue #7897)
* _BSim_. Function names in the BSim Overview Results table now update if they are changed in the program. (GP-5604, Issue #7903)
* _BSim_. Upgraded Postgres for BSim to version 15.13 and JDBC driver to 42.7.6.  This resolves issues with building PostgreSQL server on newer releases of Linux and compiler toolchains which compile with `-std=c23` option by default. (GP-5680, Issue #8122)
* _Byte Viewer_. Byteviewer now centers the cursor on the screen when going to a new offscreen location instead of putting the cursor at the top or bottom. (GP-2148)
* _Calling Conventions_. Corrected specifications for parameter and return storage of homogeneous float aggregate types in AARCH64.cspec. Made a number of improvements and corrections to AARCH64_win.cspec. (GP-5192, Issue #8016)
* _Data Types_. Improved handling of datatype removal and the impact it can have within Structure and Union components.  Previously, affected components were removed, causing unknown loss of information.  With this change, components will be preserved with the use of a `BadDataType`, allowing their size and field names to be preserved.  Each affected component comment will also be updated to indicate the name of the datatype that was removed.  A similar situation for a Structure bit-field will revert its base datatype to an appropriate primitive integer type if it had been based upon a deleted Enum or Typedef. (GP-2949)
* _Data Types_. Fixed issue where a datatype node in the datatype tree had a stale tool tip if a datatype it contained was renamed. (GP-5434)
* _Data Types_. Improved Structure Editor `unpack` action to include typedef of arrays and structures.  This change also corrects unpacking of structures which contain zero-length components. (GP-5527, Issue #7528)
* _Debugger_. Fixed issue where, when hovering over struct members, the left-hand side of assignment statements gave incorrect values. (GP-3450, Issue #5337)
* _Debugger_. Provided better launcher defaults. (GP-4611)
* _Debugger_. Added various Debugger launchers, especially Windows equivalents of existing Linux launchers.  Fixed launch logic for targets and arguments with spaces in their paths. (GP-5360, Issue #4977)
* _Debugger:Agents_. Integrated timeline for `dbgeng-trace` connector. Navigating in the __Time__ window or using the __Go-To Time__ action now issues the corresponding `!tt` command, and vice versa. (GP-4209)
* _Debugger:Agents_. Replaced the experimental pyTTD implementation with direct use of the Microsoft DLLs;  enables heap / memory visualization based on LINQ queries in the Memview Display. (GP-5407)
* _Debugger:Agents_. Added __Image__ option to __remote gdb__ and __remote lldb__ connectors. (GP-5538, Issue #7955)
* _Debugger:Agents_. The connectors will now prompt to automatically remedy some missing setup steps. (GP-5551)
* _Debugger:Breakpoints_. Added __Set Breakpoint__ drop-down action. (GP-4546)
* _Debugger:dbgeng.dll_. Added a few more options for dbgeng targets. (GP-5270)
* _Debugger:drgn_. Added type annotations to drgn. (GP-5511)
* _Debugger:Emulator_. Moved display of the current time (schedule) from Threads to the Listing's tabs. (GP-5265)
* _Debugger:Listing_. Fixed issue where Dynamic and Static Listings could get out of sync when another component directed navigation (i.e., not directly input-driven). (GP-5548)
* _Debugger:LLDB_. Added documentation to bootstrap pip into the Android NDK's lldb. (GP-5533)
* _Debugger:Memory_. The primary __Dynamic Listing__ and __Memory Bytes__ windows are now synchronized. (GP-3405)
* _Debugger:Stack_. Improved stack unwinder to handle the ARM `bx` instruction. (GP-3771, Issue #5658)
* _Debugger:Targets_. Added a __busy__ indicator to each connection and target. (GP-4080)
* _Debugger:Time_. Added __PC__, __Function__, and __Module__ columns to the __Time__ window. Changed default visibility and widths. (GP-5264)
* _Debugger:Time_. Added a __Time__ column to the __Time__ window. Hid the __Snap__ and __Snapshot__ columns by default. (GP-5499)
* _Debugger:Time_. Double-clicking or pressing `Enter` on a row in the __Time Selection__ dialog now confirms the dialog. (GP-5674)
* _Decompiler_. The Decompiler simplifies new situations where optimized code packs multiple variables into a single register. (GP-5240, Issue #7277)
* _Decompiler_. Updated Decompiler highlighting to ignore syntax tokens. (GP-5414, Issue #7527)
* _Decompiler_. Fixed a performance issue seen in the Decompiler when using a large number of custom global highlighters. (GP-5477, Issue #7520)
* _Decompiler_. Enabled optimizations for C++ source files when compiling native executables on Windows. (GP-5543, Issue #7953)
* _Decompiler_. Updated the Decompiler to now show a warning when executing DockingActions while the Decompiler is busy. (GP-5572, Issue #7893)
* _Documentation_. Updated BSim documentation to mention PostgreSQL support on arm64. (GP-5384, Issue #7387, #7388)

* _Function Tags_. Added __Make Selection__ action to Function Tags Window. (GP-5354)
* _GhidraGo_. Improved GhidraGo CLI to print correct usage upon invalid/missing GhidraURL argument. (GP-5504)

### Notable API Changes
* _API_. (GP-5458) `GhidraProject.openProject()` now throws `NotFoundException, NotOwnerException, LockException`.
* _API_. (GP-5591) Removed unused and unsupported `DataType.getDocs()` method.
* _Debugger_. (GP-2040) Deleted `AbstractAsyncServer`, `AsyncClaimQueue`, `AsyncLock`, `AsyncLoop`, `AsyncPairingCache`, `AsyncRace`, `AsyncSequence*`, `BitmaskSet`, `DebugByteChannel`, `TypeSpec` and related, without replacements.
* _Debugger_. (GP-3450) Added `UnwoundFrame.evaluate(Program, Varnode, AddressSetView)`.
* _Debugger_. (GP-5379) Most accessor methods on `TraceUniqueObject` derivatives now require a `snap` argument. For getters, this is the snap for which the value is sought. For setters, this implies the effect is from that snap onward. In most cases, the GUI's current snap is suitable. (The deprecated legacy-mode objects ignore the argument.) This required argument has cascaded throughout many other parts of the API: `DebuggerStaticMappingService`, `AutoMapSpec`, `MapProposal.MapEntry`, `DebuggerStaticMappingService`, `ProgramModuleIndexer`, `DebuggerObjectActionContext`, `DebugerSectionActionContext`, `BreakpointActionSet`, and `*EmuBreakpointActionItem`. Additionally, `getLifespan` and similar, including setters and "split-and-set," have been removed from most `TraceObjectUnique` derivatives. For cases where you need to check if the object is valid at a particular time, use `isValid(long)`. For cases where you need to enumerate (e.g., to plot) the life, use the underlying `TraceObject`. To truncate the life of an object, use `remove(long)`. For `TraceThread` in particular, the destruction snap is now considered part of its life, which is consistent with how every other object has been treated. Connectors should (and already have been) using `remove`, which sets the "destruction snap" to the one preceding the current.
* _Debugger:Agents_. (GP-4209) On the Python side: The ghidratrace package is now type-checked using mypy. As a result, the annotations used for the method registry now use `typing.Annotated` when parameters need additional description. `Client.create_trace()` now also requires a named parameter `extra`. On the Java side: Added `TraceTimeManager.findScratchSnapshot`. The trace-rmi protocol has also changed.
* _Debugger:Agents_. (GP-5538) Powershell is now supported as a debug launcher language on Windows.
* _Debugger:Breakpoints_. (GP-4546) TraceRmi methods with `action="break_ext"` now appear in the new drop-down. TraceRmi methods can now also specify their menu icon, as well as the text for their confirmation button in parameter dialogs. These are the `icon` and `ok_text` attributes, respectively. The `icon` attribute should be the id of an icon given in a theme.properties file.
* _Debugger:dbgeng.dll_. (GP-5678) Added `DebuggerListingService.getAutoReadMemorySpec()`. Moved `AutoReadMemorySpec` into the Debugger-api module. Created `AutoReadMemorySpecFactory` and refactored accordingly.
* _Debugger:Listing_. (GP-616) Added `Trace.getBaseDataTypeManager()` method.  Added `TracePlatform.getDataTypeManager()` method.  Added `TraceBasedDataTypeManager.getPlatform()` method.  `TraceDefinedDataView.create()` now takes optional `platform` argument.  Added `TraceVariableSnapProgramView.setPlatform()` method.  `DebuggerPlatformService.setCurrentMapperFor()` has an additional `focus` parameter.  Most methods in `DebuggerPlatformMapper` now take both `object` and `snap` parameters.  Added `AbstractDebuggerPlatformMapper.getDisassemblyPlatform()` method.  `DbgengX64DisassemblyInject.Mode` and related methods moved to `DbgengDebuggerPlatformOpinion`.
* _Debugger:Listing_. (GP-5548) Added `DebuggerStaticSyncService` interface and its Plugin implementation. Moved `DebuggerOpenProgramActionContext` into API project. Added `DebuggerConsolePlugin.clear()` method.
* _Debugger:Memory_. (GP-3405) Added `TraceHighlightEvent`.
Added `TrackingChangedPluginEvent`.
Added `AbstractLocation/Selection/HighlightPluginEvent`.
* _Debugger:Objects_. (GP-5425) Several protected abstract methods in `AbstractTarget` are removed without replacement. `Target.collectActions` now requires an argument specifying how its object arguments are gathered.
* _Debugger:Stack_. (GP-3771) Added `UnwindInfo.maskOfReturn`.
* _Debugger:Time_. (GP-5523) Added `TimeRadix` class. Added `TraceTimeManager.set/getTimeRadix` methods. `TraceSchedule.toString` and `.parse` methods now accept radix argument. `Span.toString` can now accept custom endpoint formatter.
* _Decompiler_. (GP-5477) Added new methods to the DecompilerHighlightService to allow function-specific highlights.
* _Framework_. (GP-5436) Deleted the Debug/Framework-AsyncComm project/module. Most of its few remaining classes were moved to Framework/Generic.
* _GUI_. (GP-5375) `GTree.forceNewNodeIntoView()` has been replaced by `GTree.whenNodeIsReady()`.
* _ProgramDB_. (GP-5742) Deprecated the use of `int` to indicate a CommentType in favor of the newly created enum.
* _Version Tracking_. (GP-4151) The Dialog Wizard API has been completely rewritten.

* _Processors_. Fixed 6x09 `COM` instruction pcode. (GP-5305, Issue #5767, #6336)
* _Processors_. Fixed ARM Thumb missing the `strt` instruction. (GP-5386, Issue #7514)
* _Scripting_. Added `RecoverClassesFromRTTIScript` check to make sure GCC VMI typeinfo structures have valid number of bases in structure. (GP-5389, Issue #7516)
* _Scripting_. PyGhidra `open_program()` now handles locked projects better. (GP-5444, Issue #7536)

# Ghidra 11.3.1 Change History (February 2025)

### Improvements
* _Multi-User_. Allow a repository without an Admin in the ACL to instantiate during server startup.  The `svrAdmin -grant` command line tool may be used to assign a new Admin to a repository.  Currently, when a user is removed from the server they are removed from all repository ACLs which could leave a repository without an Admin which will fail on server startup. (GP-5368)

### Bugs
* _Basic Infrastructure_. Fixed a bug that prevented Ghidra from remembering the last-used JDK when the `JAVA_HOME` environment variable was set. (GP-5381, Issue #7503)
* _Debugger:LLDB_. Fixed an issue with local-lldb.bat. (GP-5347, Issue #4977)

The Swift Demangler now demangles the `Swift.Int` type to `__int64` (or `__int32` on 32-bit programs) to avoid conflicts with non-Swift structures and functions that may be found in the program. (GP-5182, Issue #6784)
* _Eclipse Integration_. GhidraDev 5.0.0 has been released which supports creating and launching new Ghidra module and scripting projects with PyGhidra support (using the PyDev Eclipse plugin). (GP-5138)
* _FileSystems_. Updated to dex2jar-2.4.24 and asm-9.7.1 libraries. (GP-5220)
* _Function_. Now prevent function auto-storage assignment for DEFAULT (`undefined`) datatype.  Changed Demangler to produce undefined-typedef in place of a DWORD-typedef when producing a default-named datatype.  Demangler will still create an empty named Structure in many cases.  Decompiler will no longer assign the `undefined` datatype to variables. (GP-4886)
* _Graphing_. Added an action to toggle between the Listing and Function Graph views (`Ctrl-Space`). (GP-4947)
* _Graphing_. Added options for which corner the Function Graph Satellite view is docked within the main Graph window. (GP-4996)

### Notable API Changes
* _Debugger:Agents_. (GP-1978) The entirety of `DebuggerObjectModel` and most of its related paraphernalia have been removed. Other parts have been refactored into other components. `DebuggerObjectModel` / `TraceRecorder` is replaced by `TraceRmi` / `Target`. `TargetObject` is replaced by `TraceObject`. Some `TargetObject` interfaces, e.g., `TargetDeletable`, do not have replacement `TraceObject` interfaces. Instead, they are implied by applicable `RemoteMethods`. Others, e.g., `TargetAccessConditioned`, are removed without replacement.  `DataType`- and `Symbol`-related objects are removed. They have not been used. If needed later, the intent is to provide rmi-based access to the trace's symbol table and data type manager. `TargetObjectSchema` is replaced by `TraceObjectSchema`. `TraceObjectKeyPath` is renamed `KeyPath`. `PathUtils` and many uses of `List<String>` have been replaced by `KeyPath`. `AnnotatedSchemaContext` and related are removed. `SshPtyFactory` and related are removed.
* _Emulator_. (GP-4643) Added `JitPcodeEmulator` and many, many related classes. `PcodeArithmetic`: changed `modBeforeStore` and `modAfterLoad` to include `AddressSpace` and `PcodeOp` parameters.  `SleighInstructionDecoder.decodeInstruction` now returns a `PseudoInstruction`. PcodeExecutor: added `getIntConst`, `getLoadStoreSpace`, `getLoadStoreOffset`, `getStoreValue`, `getBranchTarget`, `getConditionalBranchPredicate`, `getIndirectBranchTarget`, `getUseropName`, `getCallotherOpNumber`.
* _BSim_. (GP-5167) Changed BSim API to convey non-default username via the `BSimServerInfo` class or the `userinfo` field of postgres/elastic BSim URLs.  The user argument has been dropped to the `FunctionDatabase.changePassword` method which will always change the password for the connected user.   Renamed `FunctionDatabase.Error` class to `FunctionDatabase.BSimError` to avoid naming conflict with `java.lang.Error`.
* _Data Types_. (GP-3625) Added `FileDataTypeManager` static methods for creating a Data Type Archive with a specific processor and compiler specification.  Improved `CParserUtils` parse methods to separate the cases where parsing into an existing Data Type Manager versus parsing into a new Data Type Archive where a processor and compiler specification may specified.
* _Debugger:Listing_. (GP-5134) `DebuggerListingProvider#setAutoReadMemorySpec` and related no longer accept `LoadEmulatorAutoReadMemorySpec`. Added `AutoReadMemorySpec#getEffective`.
* _Decompiler_. (GP-5085) Updated `DecompileOptions` to remove the `getFunctionColor()` method. There is no replacement for this method as the function color is now being set in the Listing Settings menu and is coordinated across the Listing and Decompile panes.
* _Demangler_. (GP-4898) Within the `Demangler` interface, Ghidra 9.2-deprecated methods were removed, Ghidra 11.3-deprecations were set on other methods, and  new methods were created.  The new methods and much of the Demangler fabric now makes use of a `MangledContext` in place of a `String`.  This allows greater flexibility in controlling how symbols get demangled.  These changes have been reflected in abstract and non-abstract methods in `AbstractDemanglerAnalzyer`.  Users of deprecated methods within `Demangler` and `DemanglerUtil` should migrate to newer methods (see javadoc).
* _GUI_. (GP-5007) Added a new widget, the `docking.KeyEntryPanel`, as a drop-in replacement for clients using the `docking.KeyEntryTextField`.  This is not a required change.
* _GUI_. (GP-5196) The static method `evaluateToLong(String s)` in `AddressEvaluator` has been moved to a new class called `ExpressionEvaluator`. Also, the `AddressInput` field component has been changed to accept Programs instead of just an AddressFactory (which is still supported) so that any dialog using an `AddressInput` component can now accept symbol names, memory block names, and mathematical expressions.
* _Importer_. (GP-5208) GFileSystems now need to implement `lookup(path, comparator)`.   Classes that fail to provide an implementation will fall back to using `lookup(path)`, and an error will be logged.
* _Search_. (GP-4911) The API script method `findBytes()` no longer supports finding matches that span gaps in the memory blocks. The internal classes for performing memory searches were completely re-written in Ghidra release 11.2. In release 11.3, the old classes were removed and uses of them in the `findBytes()` method were replaced with the new memory search code. The new search API currently does not support matches that span non-contiguous memory and it isn't clear if that is actually useful; so for now, that method was deprecated and no longer finds matches in gaps even if the boolean is true. In the unlikely event someone actually uses this, please contact the Ghidra team.
* _Assembler_. (GP-5288) Added `AssemblyResolvedPatterns.withContext`.  Added `ContextCommit.getWordIndex` and `getMask`.
* _BSim_. (GP-1830) Dropped use of `json-simple` library in favor of `gson`.
* _Debugger_. (GP-5271) Added `TraceBreakpoint.isAlive(long snap)`.  Deprecated `TraceBreakpoint.getLifespan()`.  Added `TraceObject.isAlive(long snap)`.
* _Debugger:Listing_. (GP-5266) Renamed `DebuggerCoordinates.equalsIgnoreRecorderAndView` to `equalsIgnoreTargetAndView`.  Added `DebuggerCoordinates.differsOnlyByPatch`.  Added `TraceSchedule.differsOnlyByPatch`.  Added `Sequence.differsOnlyByPatch`.
* _Debugger:Memory_. (GP-5164) Renamed `DebuggerAddRegionDialog#setName` to `setPath`.

This will allow an idle connection to be disconnected without the need to exit Ghidra or removing a server entry, which, in the case of a local H2 database, will allow another process to use it. (GP-4867, Issue #6703)
* _Byte Viewer_. Extended HexInteger to other integral data types. (GP-4709, Issue #6658, #6659)
* _CodeCompare_. Added ability to add functions to the last function comparison window. (GP-4634)

### Notable API Changes
* _Search_. (GP-4559)
The MemorySearchService has been changed. This had been a very specific service API created to support just one plugin and was not generally useful. The three existing methods have been consolidated into one method. The old service has been marked as deprecated and may be removed in future releases. If, in the unlikely event that anyone is using this service, please contact the Ghidra team to discuss your use case.
* _Data Types_. (GP-4949)
Added API method `Structure.setLength(int length)` which allows the size of a non-packed structure to be set.
* _Debugger:Agents_. (GP-4847)
`LaunchConfigurator.configureLauncher()` is changed such that `arguments` now requires `ValStr<?>` instead of just `?` for its values. This affects both the new Trace-RMI launchers and the deprecated object-model launchers.

* _Analysis_. Fixed issues related to analysis flag and how it affects asking the user to analyze a new program. (GP-3282)
* _Analysis_. By default, pointer-to-pointer analysis is turned off for ARM binaries in the Operand and Data Reference analyzers. This can result in fewer references created, and can be turned back on if your binaries use pointer data in memory instead of offset values from the current PC. (GP-3335)
* _API_. Fixed bug on pinned symbols when changing image base. (GP-3178, Issue #4290)
* _API_. Revised `ApplyFunctionSignatureCmd` to allow use where function should not get renamed when signature applied. (GP-3350)

* _CParser_. Fixed parsing of Windows `wdm.h` header file with multi-line strings passed as arguments to a macro. (GP-2809, Issue #4690)
* _CParser_. `CParser.parse(String)` method no longer throws an exception, and, when parsing a structure as a string, the return type will be the structure--not the last member of the structure. (GP-3183, Issue #4903)
* _CParser_. Removed `wchar_t` as a keyword when parsing header files. `wchar_t` will always use the built-in `wchar_t` datatype even if defined with a `typedef` within a header file. (GP-3215, Issue #5108)
* _CParser_. Fixed issue with CParser creating `#define` enum values if unsigned long is specified with parentheses around the value; for example, `#define X (4ul)`. (GP-3216, Issue #5069)
* _CParser_. Pressing __Cancel__ during parsing of header files is now more responsive. (GP-3284, Issue #5181)

* _CParser_. Fixed expansion of `#define` statements embedded in `#include` files and parsing of constants with `UL`/`LL` size specifications. (GP-3310, Issue #5207)
* _CParser_. Fixed CParser issues with forward-declared Enums and typedefs used within the body of functions. (GP-3371, Issue #3526, #5271)
* _CParser_. `Enum` sizes are now set to the size of an `int` for the processor (formerly 4), and `enum`s from `#define`s are set to the the smallest `enum` size that will fit the number (formerly 8). Future change will add packed `enum` sizes. (GP-3385)
* _Data_. Corrected handling of zero-length components in the form of Listing DataComponent CodeUnits. These were incorrectly reporting a length of 0 instead 1; all Listing Data, including DataComponents, must report a positive non-zero length. (GP-3314)
* _Data Types_. Automatically created class structures now respect the __Preferred Root Namespace Category__ property. (GP-1123, Issue #3196)
* _Data Types_. Added support for floating-point data types to parse decimal string representation. A significant refactor of FloatFormat and BigFloat was completed. BigFloat is now used as the value class for all float data types. Introduced `DataType.getAlignedLength()` method which was needed to differentiate between the _raw_ encoding size and the _aligned_ (i.e., padded) size used by a compiler when allocating storage (i.e., `sizeof`). Example: for x86-32 gcc, 80-bit float has an aligned-length of 12-bytes which reflects compiler's `sizeof(long double)`. (GP-1379)
* _Data Types_. Corrected 80-bit floating point support to include decode, encode, and computation via the FloatFormat and BigFloat support classes. (GP-3022, Issue #4853)

Removed 4 unnecessary classes in emulator: `RequireHasKnownTraceCachedWriteBytesPcodeExecutorState`, `RequireHasKnownTraceCachedWriteBytesPcodeExecutorStatePiece`, `RequireIsKnownTraceCachedWriteBytesPcodeExecutorState`, and `RequireIsKnownTraceCachedWriteBytesPcodeExecutorStatePiece`. (GP-3280)

* _Debugger:Mappings_. __Map Identically__ and __Map Manually__ actions will now refuse to overwrite existing mappings. (GP-3086)
* _Debugger:Trace_. Fixed a bug that allowed the user to undo a trace's initial transaction. This would lead to a subsequent `NullPointerException`. (GP-3213)
* _Debugger:Trace_. Fixed issue with __Undo__ not being effective immediately. (GP-3358)
* _Decompiler_. Fixed a Decompiler decoding error that occurred when a pre-comment contained a null character. (GP-3002, Issue #4836)
* _Decompiler_. Line breaks in Decompiler output can no longer disable a comment annotation. (GP-3029)
* _Demangler_. Fixed missing use of `wchar_t`, `wchar16`, and `wchar32` primitives in Demanglers. (GP-3184, Issue #5080)

* _Exporter_. For programs imported with the PE and ELF loaders, new exporters are available that write back to the original file layout. Any file-backed bytes that were modified by the user in the program database will be reflected in the written file (except on relocations). Writing back a modified Memory Map is not supported. (GP-786, Issue #1501, #1505, #19)
* _Graphing_. Added Graph -> Data  actions to the Code Browser, allowing visualization of specified pointer relationships in a graph. (GP-194)
* _Scripting_. Added prototype RecoverClassesFromRTTIScript and that uses RTTI information to enhance Ghidra's knowledge of class hierarchy, class member function types (constructors, destructors, deleting destructors, clones) and class member data. The script will label and put member functions into correct class namespace and apply new class structures created either using PDB information, if available, or Decompiler pcode information. (GP-339)
* _Scripting_. Added an example script, LocateMemoryAddressForFileOffset, to demonstrate mapping of a location in the original imported file to the program memory address. Useful for cases where the original file offset is known; for example, a YARA rule match. (GP-782)
* _Scripting_. Created a script to allow users to search for image base offsets to the current cursor location in 32-bit and 64-bit programs. (GP-863)

* _Analysis_. Ghidra analysis is now aware of more PE/Windows non-returning functions. (GP-733, Issue #2111)
* _Analysis_. `ResolveX86orX64LinuxSyscallsScript` now properly marks non-returning syscalls. (GP-868, Issue #2761)
* _API_. Revised Structure and Union API, and associated editor, to eliminate the use of the terms Unaligned/Aligned in favor of a packing enablement designation. Also corrected various change notification issues which may improve archive synchronization and merge behavior. (GP-862, Issue #2681)
* _API_. Renamed `Datatype.isDynamicallySized()` to `DataType.hasLanguageDependantLength()` to avoid confusion. This method is used internally to differentiate between fixed-length types and those whose length is determined by the compiler specification's data organization (e.g., pointers). (GP-932)
* _Basic Infrastructure_. Improved error reporting when trying to launch Ghidra from the git repo without Eclipse having compiled it. (GP-815, Issue #2872)
* _Build_. Command `gradle -I gradle/support/fetchDependencies.gradle init` now downloads the Function ID datasets from the ghidra-data GitHub repository so they will be automatically included in development mode and custom builds. (GP-678, Issue #1007)
* _Build_. Performing a `gradle clean` no longer deletes downloaded dependencies. The top-level flatRepo directory has been replaced with the dependencies directory. (GP-811, Issue #1663)

* _Decompiler_. Added the Max Instructions per Function Decompiler tool option, specifying the maximum number of instructions the Decompiler will decode in a single function before throwing an exception. Previously, this had been a hard-coded limit. (GP-767, Issue #2557)
* _Decompiler_. The Decompiler now propagates datatypes across signed comparison operations, so constant integer and enum values display correctly. (GP-802, Issue #2565)
* _Demangler_. Updated the GNU Demangler Analyzer options to provide a list of available formats from which to choose. (GP-94, Issue #2214)
* _Demangler_. Updated the GNU Demangler's Namespace-building to improve analysis performance. (GP-706, Issue #2509)

* _Graphing_. Added capability to collapse and expand nodes in the default graph display. (GP-371)
* _Graphing_. Upgraded jungrapht to version 1.1. (GP-377)
* _Graphing_. Refactored graph exporters into a more extensible framework. (GP-440)
* _Graphing_. Graph layout algorithms can now be chosen programmatically. (GP-551)
* _Graphing_. Created additional modified versions of the MinCross layout algorithms, all named to start with Vertical Hierarchical Min-Cross, so that they accept a favoredEdge predicate. When an edge is favored, a pass though the graph layers attempts to align those edges vertically. (GP-625)
* _Graphing_. Added an option to change the background color of the Function Graph window. (GP-760, Issue #1324)
* _Graphing_. Updated Function Graph edge routing when applying the Use Condensed Layout option to reduce edges being clipped by vertices. (GP-768)
* _Graphing_. Added option to disable the lightening of edges in the Function Graph. (GP-769, Issue #1106)

* _Graphing_. Added Vertex and Edge attributes to GraphML export format. (GP-957, Issue #2958)
* _GUI_. Added new Copy Special actions: Python Byte String, Python List, and C Array. (GP-210, Issue #744)
* _GUI_. Updated the Listing to allow structure members to display Plate Comments. (GP-421, Issue #2091)
* _GUI_. Copy/Pasting and Dragging data types now uses a progress monitor. (GP-422, Issue #2379)
* _GUI_. Added right-click menu Data -> Save Image action to allow user to export embedded graphic resource images. (GP-426)
* _GUI_. Changed Symbol Comment Annotation to use the existing symbol when available. This allows for the direct navigation of that symbol's address instead of using the search feature of the Go To Service. (GP-675)
* _GUI_. Added the Shift-F10 keybinding to allow users to show the popup context menu over the currently focused item. The Menu Key can also be used on supporting keyboards. (GP-732, Issue #2790)
* _GUI_. Fixed/Improved the behavior of global menu items and toolbar items with respect to which windows they appear in. These actions can now easily be configured to be either 1) only in menu bar and tool bar of the main window, 2) in the menu bar and tool bar of all windows, or 3) only in the windows that have components that generate the type of context that the action consumes. Added methods to the ActionBuilder class to support these three options. Also, updated numerous actions to make sure they appear in the appropriate windows. (GP-759)
* _GUI_. Improved overall UI responsiveness when performing analysis with the Symbol Table open. (GP-788)

* _Importer:ELF_. Added ELF import support for SHN_MIPS_TEXT and SHN_MIPS_DATA symbol section index values and provided ability for other processor-specific ELF extensions to resolve ELF symbol memory addresses. (GP-664)
* _Importer:ELF_. Changed various ELF relocations to detect and mark unsupported data relocations which refer to the EXTERNAL block. Applied EXTERNAL data relocations, which have a non-zero offset from the external symbol, will still be incorrect but will have an error bookmark to flag the condition. The relocation addend will not be applied in this case to avoid references to a completely irrelevant symbol in the EXTERNAL block. (GP-1029)
* _Importer:Mach-O_. Improved support for Mach-O object files. (GP-700)
* _Importer:PE_. CustomAttrib blobs in CLI/.NET metadata are now decoded. (GP-414)
* _Importer:PE_. Created proper external references for PE Delay Load Imports. (GP-674, Issue #2554, #2623)
* _Importer:PE_. PeLoader can now read and interpret the `.pdata` section of PE files that include exception handling data. (GP-729)
* _Importer:PE_. Added .exports XML files for the mfc71.dll and mfc71u.dll libraries. Having them allows Ghidra to translate ordinal imports from applications compiled against MFC 7.1 (from Visual Studio .NET 2003) to class and function names with parameters. (GP-1010, Issue #3051)
* _Listing_. Improved Listing view performance, especially noticeable on functions with excessively large stack frames. (GP-268, Issue #109, #2351)
* _Listing_. Added a tool option to hide function auto-comments that appear, trailing a function call in the Listing. (GP-752)

* _Decompiler_. The Decompiler's analysis of array accesses is much improved. It can detect more and varied access patterns produced by optimized code, even if the base offset is not contained in the array. Multi-dimensional arrays are detected as well. (GP-238, Issue #461, #1348)
* _Decompiler_. Extended the Decompiler's support for analyzing class methods. The class data type is propagated through the this pointer even in cases where the full prototype of the method is not known. The methods `isThisPointer()` and `isHiddenReturn()` are now populated in HighSymbol objects and are accessible in Ghidra scripts. (GP-239, Issue #2151)
* _Decompiler_. The Decompiler will now infer a string pointer from a constant that addresses the interior of a string, not just the beginning. (GP-240, Issue #1502)
* _Decompiler_. The Decompiler now always prints the full precision of floating-point values, using the minimal number of characters in either fixed point or scientific notation. (GP-241, Issue #778)
* _Decompiler_. The Decompiler's Auto Create Structure command now incorporates into new structures data-type information from function prototypes. The Auto Fill in Structure variant of the command will override undefined and other more general data-types with discovered data-types if they are more specific. (GP-242)
* _Demangler_. Modified Microsoft Demangler (MDMang) to handle symbols represented by MD5 hash codes when their normal mangled length exceeds 4096. (GT-3409, Issue #1344)
* _Demangler_. Upgraded the GNU Demangler to version 2.33.1. Added support for the now-deprecated GNU Demangler version 2.24 to be used as a fallback option for demangling. (GT-3481, Issue #1195, #1308, #1451, #1454)
* _Demangler_. The Demangler now more carefully applies information if generic changes have been made. Previously if the function signature had changed in any way from default, the demangler would not attempt to apply any information including the function name. (GP-12)
* _Demangler_. Changed MDMang so cast operator names are complete within the qualified function name, effecting what is available from internal API. (GP-13)
* _Demangler_. Added additional MDMang Extended Types such as `char8_t`, `char16_t`, and `char32_t`. (GP-14)
* _Documentation_. Removed Eclipse BuildShip instructions from the DevGuide. (GT-3634, Issue #1735)

* _GUI_. Updated Ghidra to allow users to set a key binding to perform an equivalent operation to double-clicking the `XREF` field in the Listing. See the Show Xrefs action in the Tool Options... Key Bindings section. (GT-3446)
* _GUI_. Improved mouse wheel scrolling in Listing and Byte Viewers. (GT-3473)
* _GUI_. Ghidra's action context mechanism was changed so that actions that modify the program are not accidentally invoked in the wrong context, thus possibly modifying the program in ways the user did not want or without the user knowing that it happened. This also fixed an issue where the navigation history drop-down menu did not represent the locations that would be used if the next/previous buttons were pressed. (GT-3485)
* _GUI_. Updated Ghidra tables to defer updating while analysis is running. (GT-3604)
* _GUI_. Updated Font Size options to allow the user to set any font size. (GT-3606, Issue #160, #1541)

* _Jython_. Upgraded Jython to version 2.7.2. (GP-109)
* _Listing_. In the PCode field of the Listing, accesses of varnodes in the `unique` space are now always shown with the size of the access. Fixed bug which would cause the PCode emulator to reject valid pcode in rare instances. (GP-196)
* _Listing:Data_. Improved handling and display of character sequences embedded in operands or integer values. (GT-3347, Issue #1241)
* _Multi-User:Ghidra Server_. Added ability to specify initial Ghidra Server user password (`-a0` mode only) for the svrAdmin add and reset commands. (GT-3640, Issue #321)

* _Processors_. Improved x86 breakpoint disassembly. (GT-3421, Issue #872)
* _Processors_. Added manual index file for the M6809 processor. (GT-3449, Issue #1414)
* _Processors_. Corrected issues related to retained instruction context during a language upgrade. In some rare cases this retained context could interfere with the instruction re-disassembly. This context-clearing mechanism is controlled by a new pspec property: `resetContextOnUpgrade`. (GT-3531)
* _Processors_. Updated PIC24/PIC30 index file to match latest manual. Added support for dsPIC33C. (GT-3562)
* _Processors_. Added missing call-fixup to handle call side-effects for 32 bit GCC programs for `get_pc_thunk.ax/si`. (GP-10)

### Bugs
* _Analysis_. Function start patterns found at 0x0, function signatures applied from the Data Type Manager at 0x0, and DWARF debug symbols applied at 0x0 will no longer cause stack traces. In addition, DWARF symbols with zero length address range no longer stack trace. (GT-2817, Issue #386, #1560)
* _Analysis_. Constant propagation will treat an OR with zero (0) as a simple copy. (GT-3548, Issue #1531)
* _Analysis_. Corrected Create Structure from Selection, which failed to use proper data organization during the construction process. This could result in improperly sized components such as pointers and primitive types. (GT-3587)
* _Analysis_. Fixed an issue where stored context is initializing the set of registers constantly. (GP-25)
* _Analysis_. Fixed an RTTI Analyzer regression when analyzing RTTI0 structures with no RTTI4 references to them. (GP-62, Issue #2153)

* _Data Types_. Fixed bug that caused Data Type Manager Editor key bindings to get deleted. (GT-3411, Issue #1355)
* _Data Types_. Updated the DataTypeParser to handle data type names containing templates. (GT-3493, Issue #1417)
* _Data Types_. Corrected pointer data type `isEquivalent()` method to properly check the equivalence of the base data type. The old implementation could cause a pointer to be replaced by a conflicting pointer with the same name whose base datatype is not equivalent. This change has a negative performance impact associated with it and can cause additional conflict datatypes due to the rigid datatype relationships. (GT-3557)
* _Data Types_. Improved composite conflict resolution performance and corrected composite merge issues when composite bitfields and/or flexible arrays are present. (GT-3571)
* _Data Types_. Fixed bug in SymbolPathParser naive parse method that caused a less-than-adequate fall-back parse when angle bracket immediately followed the namespace delimiter. (GT-3620)

* _Decompiler_. Fixed a bug in the Decompiler that caused load operations from volatile memory to be removed as dead code. (GP-245, Issue #393, #1832)
* _Decompiler_. Fixed a bug causing the Decompiler to miss a stack alias if its offset was, itself, stored on the stack. (GP-246)
* _Decompiler_. Fixed a bug causing the Decompiler to lose Equate references to constants passed to functions that were called indirectly. (GP-247)
* _Decompiler_. Addressed various situations where the Decompiler unexpectedly removes active instructions as dead code after renaming or retyping a stack location. If the location was really an array element or structure field, renaming forced the Decompiler to treat the location as a distinct variable. Subsequently, the Decompiler thought that indirect references based before the location could not alias any following stack locations, which could then by considered dead. As of the 9.2 release, the Decompiler's renaming action no longer switches an annotation to `forcing` if it wasn't already. A retyping action, although it is `forcing`, won't trigger alias blocking for atomic data-types (this is configurable). (GP-248, Issue #524, #873)
* _Decompiler_. Fixed decompiler memory issues reported by a community security researcher. (GP-267)
* _Decompiler_. Fix for Decompiler error: `Pcode: XML comms: Missing symref attribute in <high> tag`. (GP-352, Issue #2360)

* _GUI_. Structure editor name now updates in title bar and tab when structure is renamed. (GP-19)
* _GUI_. Fixed an issue where drag-and-drop import locks the Windows File Explorer source window until the import dialog is closed by the user. (GP-27)
* _GUI_. Fixed an issue in GTreeModel where fireNodeChanged had no effect. This could result in stale node information and truncation of the text associated with a node in a GTree. (GP-30)
