Contrib. Extensions are now installed to the user's settings directory, not the Ghidra installation directory. (GT-3639, Issue #1960)

Data Types. Added mutability data settings (constant, volatile) for Enum datatype. (GT-3415)

Data Types. Improved Structure Editor's Edit Component action to work on array pointers. (GP-205, Issue #1633)

Decompiler. Added Secondary Highlights to the Decompiler. This feature allows the user to create a highlight for a token to show all occurrences of that token. Further, multiple secondary highlights are allowed at the same time, each using a unique color. See the Decompiler help for more information. (GT-3292, Issue #784)

Decompiler. Added heuristics to the Decompiler to better distinguish whether a constant pointer refers to something in the CODE or DATA address space, for Harvard architectures. (GT-3468)

Decompiler. Improved Decompiler analysis of local variables with small data types, eliminating unnecessary casts and mask operations. (GT-3525)

Decompiler. Documentation for the Decompiler, accessible from within the Code Browser, has been rewritten and extended. (GP-166)

Decompiler. The Decompiler can now display the namespace path (or part of it) of symbols it renders. With the default display configuration, the minimal number of path elements necessary are printed to fully resolve the symbol within the current scope. (GP-236)

Decompiler. The Decompiler now respects the Charset and Translate settings for string literals it displays. (GP-237)

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)

FID. Regenerated FunctionID databases. Added support for Visual Studio versions 2017 and 2019. (GP-170)

GUI. Improved the performance of the Defined Strings table. (GT-3414, Issue #1259)

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)

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. Default Decompiler options now minimize the risk of losing code when renaming or retyping variables. (GT-3577)

Decompiler. The Decompiler no longer inherits a variable name from a subfunction if that variable incorporates additional data-flow unrelated to the subfunction. (GT-3580)

Decompiler. Fixed the Decompiler Override Signature action to be enabled on the entire C-code statement. (GT-3636, Issue #1589)

Decompiler. Fixed frequent ClassCast and IllegalArgument exceptions when performing Auto Create Structure or Auto Create Class actions in the Decompiler. (GP-119)

Decompiler. Fixed a bug in the Decompiler that caused PTRSUB off of non-pointer type exceptions. (GP-244, Issue #1826)

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)

Decompiler. Fixed bug preventing the Decompiler from seeing Equates attached to compare instructions. (GP-369, Issue #2386)

Demangler. Fixed the GnuDemangler to parse the full namespace for operator symbols. (GT-3474, Issue #1441, #1448)

Demangler. Fixed numerous GNU Demangler parsing issues. Most notable is the added support for C++ Lambda functions. (GT-3545, Issue #1457, #1569)

Demangler. Updated the GNU Demangler to correctly parse and apply C++ strings using the unnamed type syntax. (GT-3645)

Demangler. Fixed duplicate namespace entry returned from getNamespaceString() on DemangledVariable. (GT-3646, Issue #1729)

Demangler. Fixed a GnuDemangler ClassCastException when parsing a typeinfo string containing operator text. (GP-160, Issue #1870, #2267)

Demangler. Added stdlib.h include to the GNU Demangler to fix a build issue on some systems. (GP-187, Issue #2294)
