> - 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)
> - Processors. The ARM instruction semantics for the mulitple-single-element forms of the `vld1`/`vst1` vector instructions have been corrected. (GP-1167)
> - Sleigh. Fixed a string formatting error in the sleigh compiler. (GP-1124, Issue #3168)

# Ghidra 10.0.1 Change History (July 2021)

> New Features

> - Decompiler. The Decompiler now supports conversion (hex, dec, bin, oct, char) and equate actions directly on constant tokens in the Decompiler window. To the extent possible, these actions also affect matching scalar operands in the listing. (GP-1053, Issue #21)

> Improvements

> - Basic Infrastructure. Ghidra now gracefully fails to launch when its path contains an exclamation point. (GP-1057, Issue #1817)
> - FileSystems. Can now handle multi-level Ext4 extent nodes when reading a file. (GP-1070)

> Bugs

> - Build. No longer building and distributing the Debugger native test binaries. (GP-1080, Issue #3160, #3177)

> - Decompiler. Fixed a bug in the Decompiler causing `Overriding symbol with different type size` exceptions. (GP-1041)
> - Exporter. PE and ELF exporters no longer error out when processing non-file-backed relocations. (GP-1091)
> - FileSystems. Corrected problem mounting Ext4 file systems when the container file is larger than the file system. (GP-1067)
> - Importer:ELF. Corrected ELF relocation error reporting, including error bookmarks, when relocation handler extension is missing. (GP-1097)
> - Jython. Added `__file__ attribute` support in Jython scripts. (GP-1099, Issue #3181)

> - Processors. Added ELF Relocation handler for SuperH processors. Only a few common relocation types have been added. (GP-1090)
> - Scripting. Fixed a potential NullPointerException that could occur when trying to run a script that doesn't exist. (GP-1074, Issue #2742)
> - Scripting. Improved graphing of class hierarchy in RecoverClassesFromRTTIScript and the GraphClassesScript to handle duplicate class names, class namespace delimiters, and to make better vertex descriptions. (GP-1095)
> - Scripting. Fixed a flaw in the RecoverClassesFromRTTIScript that was not using PDB information to create data member names in class data structures. (GP-1101)

# Ghidra 10.0 Change History (June 2021)

> New Features

> - Debugger. Introduced the Debugger, along with GDB and dbgeng.dll connectors for debugging user-mode applications on Linux and Windows, respectively. 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. Function signatures, including return types and argument data types, are now decoded from CLI Metadata for .NET binaries. (GP-327)
> - Analysis. Switched #Strings table processing from ASCII to UTF-8 for CIL binaries. (GP-330, Issue #423)
> - Analysis. Added Constant, Assembly, and AssemblyRef blob processing for CIL binaries. (GP-465)
> - Analysis. Added the Variadic Function Signature Override analyzer, which identifies functions that take a format string as a parameter and applies the correct signature override at each call site. (GP-516)
> - Analysis. Added ability to save and easily reuse analysis options in customer-defined configurations. (GP-544, Issue #2182, #312)
> - 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)
> - Build. Ghidra now requires Gradle 6.0 or later to build. Gradle 7.x is now supported. (GP-849, Issue #2949)
> - Build. Made changes to gradle code to remove warnings. (GP-993, Issue #3039)
> - Data Types. Added support for hexadecimal byte offset display within composite bitfield view. (GP-910, Issue #2959)
> - Decompiler. Decompiler analysis now automatically identifies and displays loop variables using standard for-loop syntax. When a loop variable is discovered, a condition, iteration, and optional initializer statement are displayed at the top of the loop. (GP-565)
> - 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)
> - Documentation. Added basic instructions on how to install, build, and develop Ghidra to README.md. (GP-847)
> - DWARF. Improved speed and memory usage when importing large DWARF binaries. (GP-419)
> - DWARF. Added M68000/SVR4 DWARF register mappings. (GP-556, Issue #1610)
> - 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 graph API method to set descriptions (tooltips) on vertices and edges. (GP-949)
> - 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)
> - GUI. Updated the Function Tags table column so that it may be used in most Ghidra tables. (GP-816, Issue #2873)
> - GUI. Updated the Defined Strings view to reload less frequently during auto-analysis. (GP-835, Issue #2889)
> - GUI. Updated function hovering in the Decompiler to find the correct function tooltip when multiple functions exist with the same name. (GP-959, Issue #2604)
> - 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)
> - Analysis. Improved constant analysis speed when processing large binaries with a large amount of code not in defined functions, such as exception handlers. (GP-746, Issue #2509)
> - Analysis. When OverlayAddressSpace was refactored and Decompiler made aware of it for Ghidra 9.2, the VarnodeContext was not aware of the overlays. This was fixed and should eliminate the NullPointerException caused when the Symbolic Propagator calls the Varnode constructor. (GP-751, Issue #2785, #2787)
> - Assembler. Fixed assembler issue with delay-slotted instructions. (GP-587)
> - Assembler. Fixed assemble Patch Instruction action to work on listings other than the primary static listing. (GP-623)
> - Assembler. Modified assembler Patch Instruction action to ignore external symbols which produced bad offsets for instructions. (GP-645)
> - Basic Infrastructure. Fixed an issue with Ghidra and its supporting launch scripts not being able to run correctly on Windows when an ampersand was in the path. Also fixed an issue with svrAdmin.bat and buildGhidraJar.bat not working if the Ghidra path contained a space. (GP-693, Issue #1726, #1728)
> - Basic Infrastructure. Corrected "LaunchSupport expected 2 to 4 arguments but got 1" error when starting Ghidra on Windows. (GP-1050, Issue #2176, #3122)

> - Build. Corrected an issue with `gradle prepDev` when the Ghidra repository is on a different drive than the user's home directory on Windows OS. (GP-970, Issue #3047, #3062)
> - Build. Fixed a bug that prevented Ghidra from launching in Single Jar Mode when its path contained a space. (GP-1039)
> - C Parsing. The C-Parser bitfield parsing has been relaxed to allow declared bitfield sizes to exceed the base datatype size. The effective bitfield size may be clamped based upon the current data organization while preserving the declared size. (GP-558)
> - Data Types. Fixed a NullPointerException that occurred when trying to edit a function datatype in a datatype archive when there was no open program in the tool. (GP-356, Issue #2407)
> - Data Types. Corrected the retention of datatype archive search paths, which did not properly remember disabled paths. (GP-639)
> - Data Types. Fixed potential deadlock encountered when working with the DataTypes tree. (GP-774, Issue #2832)
> - Decompiler. Fixed endianess issue for joined, two-register returns of `longlong` values for MIPS 32-bit little endian variants. (GP-513)
> - Decompiler. The Decompiler no longer emits comments in the middle of conditional expressions. (GP-621, Issue #1670)
> - Decompiler. Fixed `Redefinition of structure...` exceptions in the Decompiler caused by a PNG Image and other opaque datatypes. (GP-820, Issue #2734)
> - Decompiler. Fixed infinite loop in the Decompiler when analyzing return values. (GP-821, Issue #2851)
> - Decompiler. Fixed bug in the Decompiler's handling of enumerated datatypes causing `Shared type id` exceptions. (GP-895, Issue #2909)

Memory block GUI has also been changed eliminate the duplicate block name restriction. (GP-420, Issue #2465)
> - Build. Eliminated the need for installation of bison and flex when performing source-based gradle build of Ghidra or the Decompiler module. The generated files are now included with source files and maintained in source control. A separate `gradle Decompiler:generateParsers` task, which still requires bison and flex, must be used, explicitly, when changes are made to lex/yacc source files. (GP-467)
> - Graphing. Fixed issue with exporting graphs to DOT format due to invalid vertex IDs. (GP-280)
> - Graphing. Improved graphing where it did not navigate when clicking on external function nodes. Now it will navigate to the fake function location in the program, which is the location of the pointer to the external function. (GP-493)
> - Listing:Symbols. Removed restriction for naming labels that resemble default label names. (GT-3185, Issue #1057)
> - PDB. Crafted PDB type ID records `0x1608` and `0x1609` with presumed class and struct types and follow-on application of these types. Also fixed up some fall-back data type logic and improved some warning messages to reflect the cause of the conditions. (GP-474, Issue #2523)

> - 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'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)

> - 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)

> - 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)
