• 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)

• 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)

• Importer. The MzLoader now populates the relocation table when relocations are performed. (GP-1160)
• Importer:ELF. Corrected dynamic GOT/PLT markup problem for images which do not contain section headers. In cases where image does not define symbols within the PLT, analysis may be relied upon for its disassembly. ELF Importer's goal is to migrate symbols which may be defined within the PLT to the External symbol space. (GP-1110, Issue #3198)
• Importer:Mach-O. The Mach-O importer now correctly interprets indirect symbols as references to symbols within another .dylib. (GP-1120)
• Importer:PE. Improved ControlFlowGuard markup and creation of functions (GP-1179, Issue #1547, #1565)
• Processors. Fixed bug in SuperH4 fmov.s pcode. (GP-1152)

The UI includes threads, timeline, modules, memory, registers, watches, etc., for examining and controlling debug targets. See Help -> Contents -> What's New for more details. (GP-986)
• 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)

Improvements

• 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)
• Demangler. Improved Demangler error checking and reporting to give underlying cause of failure. (GP-850)

• DWARF. Improved handling of zero-length structure components during DWARF processing. (GP-851, Issue #2191)
• Exporter. Made various improvements and bug fixes and to the IDA Pro exporter. (GP-831, Issue #1897, #2788, #2882, #2891)
• FileSystems. Added support for recognizing unencrypted DMG files. (GP-845)
• Framework. Added support for program-specific extensions to a compiler specification. Users can now define their own calling conventions and call-fixups to integrate into decompilation and other analysis (see help for Specification Extensions). (GP-653)
• 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 a distinct visual edge highlight beyond just a different color for graph edge selection. (GP-793, Issue #2953)
• Graphing. Added Display as Graph action to the Data Type Manager, allowing visualization of embedded and referenced types of the selected types. (GP-808)
• Graphing. Fixed function graph bug that prevented the satellite view from showing the primary view lens. Fixed a layout bug that allowed some vertices to get clipped when condensing the graph. (GP-940)

• 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 markup to ELF import for .note.gnu.build-id and .gnu_debuglink sections. (GP-468)
• 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)
• PDB. Improved Ghidra's ability to find and pull PDB files from symbol servers and symbol storage locations. (GP-42)
• Processors. Simplified PIC24 return instruction semantics. (GP-647)
• Processors. Added support for register alias specification within processor spec (*.pspec). Added WREG register aliases for PIC24 processor variants. (GP-901, Issue #2956)
• Processors. Fixed issue with the PPAGE register not being properly restored after CALL instructions in the HCS12 processor. (GP-920, Issue #1099)
• Processors. Fixed HCS12 IDX1 addressing with negative immediate values. (GP-937, Issue #3008)
• Processors. Fixed V850 multiply-by-immediate calculation that produced an incorrect value when the fifth bit was set. (GP-939, Issue #2970)
• References. Improved performance of reference management for special cases when large a number of references from the same address exist (e.g., entry point designation). (GP-696)
• Scripting. ExportImageScript now exports all images within a user-selected region to files within a user-selected folder. (GP-231)
• Scripting. Improved TableChooserDialog, allowing multiple rows to be processed at once. (GP-676)
• Scripting. Updated the TableChooserDialog to allow clients to set the default column sort. (GP-792)
• Scripting. Added Python script comment block support. (GP-843, Issue #1484, #2846)
• Scripting. Added ApplyClassFunctionSignatureUpdatesScript and ApplyClassFunctionDefinitionUpdatesScript fix-up scripts that can be applied if a user makes changes to a virtual function recovered by the RecoverClassesFromRTTIScript. Both scripts identify differences between Function Signatures in the Listing and Function Definitions in the Data Type Manager, but the first script fixes all changes to match the signature and the second to match the definition. (GP-973, Issue #3081)
• Sleigh. Debug info for Sleigh constructors now includes source file names. (GP-233)
• Sleigh. The Sleigh compiler now issues a warning if it generates a temporary varnode which might be large enough to overlap another temporary varnode. (GP-520)
• Sleigh. While register names should remain case-sensitive within a Sleigh spec during compilation/parse, register names must not duplicate in a case-insensitive manner since the Program API provides a case-insensitive register lookup by name. The Sleigh Compiler now enforces this. (GP-927)

Bugs

• Analysis. Fixed how managed code entry points in .NET binaries with CIL entry points are detected and labeled. (GP-319)
• Analysis. Can now process implementation-specific data structures for Microsoft CIL compilers. (GP-461)
• Analysis. Corrected processing for pointers, function pointers, custom modifiers, ValueTypes, static methods, MethodRefs, MethodDefs, and PInvokes found in .NET mixed binaries. (GP-656)

• 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)

• 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)

• 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)
