<H1 align="center">Ghidra 9.2 Change History (November 2020)</H1>
<blockquote><p><u>New Features</u></p>
<ul>
<li><I>Graphing</I>. A new graph service and implementation was created. The graph service provides basic graphing capabilities. It was also used to generate several different types of graphs including code block graphs, call graphs, and AST graphs. In addition, an export graph service was created that supports various formats. (GP-211)</li>
<li><I>PDB</I>. Added a new, prototype, platform-independent PDB analyzer that processes and applies data types and symbols to a program from a raw (non-XML-converted) PDB file, allowing users to more easily take advantage of PDB information. (GT-3112)</li>
<li><I>Processors</I>. Added M8C SLEIGH processor specification. (GT-3052)</li>
<li><I>Processors</I>. Added support for the RISC-V processor. (GT-3389, Issue #932)</li>
<li><I>Processors</I>. Added support for the Motorola 6809 processor. (GT-3390, Issue #1201)</li>
<li><I>Processors</I>. Added CP1600-series processor support. (GT-3426, Issue #1383)</li>

</ul>
</blockquote>
<blockquote><p><u>Improvements</u></p>
<ul>
<li><I>Analysis</I>. Increased the speed of the Embedded Media Analyzer, which was especially poor for large programs, by doing better checking and reducing the number of passes over the program. (GT-3258)</li>
<li><I>Analysis</I>. Improved the performance of the RTTI analyzer. (GT-3341, Issue #10)</li>
<li><I>Analysis</I>. Updated Auto-analysis to preserve work when encountering recoverable exceptions. (GT-3599)</li>
<li><I>Analysis</I>. Improved efficiency when creating or checking for functions and namespaces which overlap. (GP-21)</li>
<li><I>Analysis</I>. Added partial support of Clang for Windows. (GP-64)</li>
<li><I>Analysis</I>. RTTI structure processing speed has been improved with a faster technique for finding the root RTTI type descriptor. (GP-168, Issue #2075)</li>
<li><I>API</I>. The performance of adding large numbers of data types to the same category has been improved. (GT-3535)</li>
<li><I>API</I>. Added the BigIntegerNumberInputDialog that allows users to enter integer values larger than <code>Integer.MAX_VALUE</code> (2147483647). (GT-3607)</li>
<li><I>API</I>. Made JSON more available using GSON. (GP-89, Issue #1982)</li>
<li><I>Basic Infrastructure</I>. Introduced an extension point <code>priority</code> annotation so users can control extension point ordering. (GT-3350, Issue #1260)</li>
<li><I>Basic Infrastructure</I>. Changed file names in <B>launch.bat</B> to always run executables from System32. (GT-3614, Issue #1599)</li>
<li><I>Basic Infrastructure</I>. Unknown platforms now default to 64-bit. (GT-3615, Issue #1499)</li>
<li><I>Build</I>. Ghidra's native Windows binaries can now be built using Visual Studio 2019. (GT-3277, Issue #999)</li>
<li><I>Build</I>. Extension builds now exclude gradlew artifacts from zip file. (GT-3631, Issue #1763)</li>
<li><I>Build</I>. Reduced the number of duplicated help files among the build jar files. (GP-57, Issue #2144)</li>
<li><I>Build</I>. Git commit hash has been added to <B>application.properties</B> file for every build (not just releases). (GP-67)</li>
<li><I>Contrib</I>. Extensions are now installed to the user's settings directory, not the Ghidra installation directory. (GT-3639, Issue #1960)</li>
<li><I>Data Types</I>. Added mutability data settings (constant, volatile) for Enum datatype. (GT-3415)</li>
<li><I>Data Types</I>. Improved Structure Editor's <B>Edit Component</B> action to work on array pointers. (GP-205, Issue #1633)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. Improved Decompiler analysis of local variables with small data types, eliminating unnecessary casts and mask operations. (GT-3525)</li>
<li><I>Decompiler</I>. Documentation for the Decompiler, accessible from within the Code Browser, has been rewritten and extended. (GP-166)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. The Decompiler now respects the <B>Charset</B> and <B>Translate</B> settings for string literals it displays. (GP-237)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. Extended the Decompiler's support for analyzing class methods. The class data type is propagated through the <B>this</B> pointer even in cases where the full prototype of the method is not known. The methods <code>isThisPointer()</code> and <code>isHiddenReturn()</code> are now populated in HighSymbol objects and are accessible in Ghidra scripts. (GP-239, Issue #2151)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. 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)</li>
<li><I>Decompiler</I>. The Decompiler's <B>Auto Create Structure</B> command now incorporates into new structures data-type information from function prototypes. The <B>Auto Fill in Structure</B> variant of the command will override <B>undefined</B> and other more general data-types with discovered data-types if they are more specific. (GP-242)</li>
<li><I>Demangler</I>. Modified Microsoft Demangler (MDMang) to handle symbols represented by MD5 hash codes when their normal mangled length exceeds 4096. (GT-3409, Issue #1344)</li>
<li><I>Demangler</I>. 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)</li>
<li><I>Demangler</I>. 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)</li>
<li><I>Demangler</I>. Changed MDMang so cast operator names are complete within the qualified function name, effecting what is available from internal API. (GP-13)</li>
<li><I>Demangler</I>. Added additional MDMang Extended Types such as <code>char8_t</code>, <code>char16_t</code>, and <code>char32_t</code>. (GP-14)</li>
<li><I>Documentation</I>. Removed Eclipse BuildShip instructions from the DevGuide. (GT-3634, Issue #1735)</li>
<li><I>FID</I>. Regenerated FunctionID databases. Added support for Visual Studio versions 2017 and 2019. (GP-170)</li>
<li><I>Function Diff</I>. Users may now add functions ad-hoc to existing function comparison panels. (GT-2229)</li>
<li><I>Function Graph</I>. Added <B>Navigation History</B> Tool option for Function Graph to signal it to produce fewer navigation history entries. (GT-3233, Issue #1115)</li>
<li><I>GUI</I>. Users can now view the Function Tag window to see all functions associated with a tag, without having to inspect the Listing. (GT-3054)</li>
<li><I>GUI</I>. Updated the <B>Copy Special</B> action to work on the current address when there is no selection. (GT-3155, Issue #1000)</li>
<li><I>GUI</I>. Significantly improved the performance of filtering trees in the Ghidra GUI. (GT-3225)</li>
<li><I>GUI</I>. Added many optimizations to increase the speed of table sorting and filtering. (GT-3226, Issue #500)</li>
<li><I>GUI</I>. Improved performance of bit view component recently introduced to Structure Editor. (GT-3244, Issue #1141)</li>
<li><I>GUI</I>. Updated usage of timestamps in the UI to be consistent. (GT-3286)</li>
<li><I>GUI</I>. Added tool actions for navigating to the next/previous functions in the navigation history. (GT-3291, Issue #475)</li>

<li><I>GUI</I>. Updated the Ghidra File Chooser so that users can type text into the list and table views in order to quickly jump to a desired file. (GT-3396)</li>
<li><I>GUI</I>. Improved the performance of the Defined Strings table. (GT-3414, Issue #1259)</li>
<li><I>GUI</I>. Updated Ghidra to allow users to set a key binding to perform an equivalent operation to double-clicking the <code>XREF</code> field in the Listing. See the <B>Show Xrefs</B> action in the <B>Tool Options... Key Bindings</B> section. (GT-3446)</li>
<li><I>GUI</I>. Improved mouse wheel scrolling in Listing and Byte Viewers. (GT-3473)</li>
<li><I>GUI</I>. 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)</li>
<li><I>GUI</I>. Updated Ghidra tables to defer updating while analysis is running. (GT-3604)</li>
<li><I>GUI</I>. Updated Font Size options to allow the user to set any font size. (GT-3606, Issue #160, #1541)</li>

<li><I>Processors</I>. Added manual index file for the M6809 processor. (GT-3449, Issue #1414)</li>
<li><I>Processors</I>. 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: <code>resetContextOnUpgrade</code>. (GT-3531)</li>
<li><I>Processors</I>. Updated PIC24/PIC30 index file to match latest manual. Added support for dsPIC33C. (GT-3562)</li>
<li><I>Processors</I>. Updated AVR8 ATmega256 processor model to reflect correct memory layout specification. (GT-933)</li>

<blockquote><p><u>Bugs</u></p>
<ul>
<li><I>Analysis</I>. Fixed an issue where stored context is initializing the set of registers constantly. (GP-25)</li>
<li><I>Analysis</I>. Fixed an RTTI Analyzer regression when analyzing RTTI0 structures with no RTTI4 references to them. (GP-62, Issue #2153)</li>
<li><I>Analysis</I>. Fixed an issue where the RTTI analyzer was not filling out RTTI3 structures in some cases. (GP-111)</li>
<li><I>API</I>. Fixed NullPointerException when attempting to delete all bookmarks from a script. (GT-3405)</li>
<li><I>API</I>. Updated the Class Searcher so that Extension Points found in the <B>Ghidra/patch</B> directory get loaded. (GT-3547, Issue #1515)</li>
<li><I>Build</I>. Updated dependency fetch script to use HTTPS when downloading CDT. (GP-69, Issue #2173)</li>
<li><I>Build</I>. Fixed resource leak in Ghidra jar builder. (GP-342)</li>
<li><I>Byte Viewer</I>. Fixed Byte Viewer to correctly load the middle-mouse highlight color options change. (GT-3471, Issue #1464, #1465)</li>
<li><I>Data Types</I>. Fixed decoding of static strings that have a character set with a smaller character size than the platform's character size. (GT-3333, Issue #1255)</li>
<li><I>Data Types</I>. Correctly handle Java character sets that do not support the encoding operation. (GT-3407, Issue #1358)</li>
<li><I>Data Types</I>. Fixed bug that caused Data Type Manager Editor key bindings to get deleted. (GT-3411, Issue #1355)</li>
<li><I>Data Types</I>. Updated the DataTypeParser to handle data type names containing templates. (GT-3493, Issue #1417)</li>
<li><I>Data Types</I>. Corrected pointer data type <code>isEquivalent()</code> 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)</li>
<li><I>Data Types</I>. Improved composite conflict resolution performance and corrected composite merge issues when composite bitfields and/or flexible arrays are present. (GT-3571)</li>
<li><I>Data Types</I>. Corrected size of <code><B>long</B></code> for AARCH64 per LP64 standard. (GP-175)</li>
<li><I>Decompiler</I>. Fixed bug causing the Decompiler to miss symbol references when they are stored to the heap. (GT-3267)</li>
<li><I>Decompiler</I>. Fixed bug in the Decompiler that caused <code>Deleting op with descendants</code> exception. (GT-3506)</li>
<li><I>Decompiler</I>. Decompiler now correctly compensates for integer promotion on shift, division, and remainder operations. (GT-3572)</li>
<li><I>Decompiler</I>. Fixed handling of 64-bit implementations of alloca_probe in the Decompiler. (GT-3576)</li>
<li><I>Decompiler</I>. Default Decompiler options now minimize the risk of losing code when renaming or retyping variables. (GT-3577)</li>
<li><I>Decompiler</I>. The Decompiler no longer inherits a variable name from a subfunction if that variable incorporates additional data-flow unrelated to the subfunction. (GT-3580)</li>
<li><I>Decompiler</I>. Fixed the Decompiler <B>Override Signature</B> action to be enabled on the entire C-code statement. (GT-3636, Issue #1589)</li>
<li><I>Decompiler</I>. Fixed frequent ClassCast and IllegalArgument exceptions when performing <B>Auto Create Structure</B> or <B>Auto Create Class</B> actions in the Decompiler. (GP-119)</li>
<li><I>Decompiler</I>. Fixed a bug in the Decompiler that caused different variables to be assigned the same name in rare instances. (GP-243, Issue #1995)</li>
<li><I>Decompiler</I>. Fixed a bug in the Decompiler that caused <code>PTRSUB off of non-pointer type</code> exceptions. (GP-244, Issue #1826)</li>
<li><I>Decompiler</I>. Fixed a bug in the Decompiler that caused load operations from volatile memory to be removed as dead code. (GP-245, Issue #393, #1832)</li>
<li><I>Decompiler</I>. Fixed a bug causing the Decompiler to miss a stack alias if its offset was, itself, stored on the stack. (GP-246)</li>
<li><I>Decompiler</I>. Fixed a bug causing the Decompiler to lose Equate references to constants passed to functions that were called indirectly. (GP-247)</li>
<li><I>Decompiler</I>. 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 <code>forcing</code> if it wasn't already. A retyping action, although it is <code>forcing</code>, won't trigger alias blocking for atomic data-types (this is configurable). (GP-248, Issue #524, #873)</li>
<li><I>Decompiler</I>. Fixed decompiler memory issues reported by a community security researcher. (GP-267)</li>
<li><I>Demangler</I>. Fixed the GnuDemangler to parse the full namespace for <code>operator</code> symbols. (GT-3474, Issue #1441, #1448)</li>
<li><I>Demangler</I>. Fixed numerous GNU Demangler parsing issues. Most notable is the added support for C++ Lambda functions. (GT-3545, Issue #1457, #1569)</li>
<li><I>Demangler</I>. Updated the GNU Demangler to correctly parse and apply C++ strings using the <code>unnamed type</code> syntax. (GT-3645)</li>
<li><I>Demangler</I>. Fixed duplicate namespace entry returned from <code>getNamespaceString()</code> on DemangledVariable. (GT-3646, Issue #1729)</li>
<li><I>Demangler</I>. Fixed a GnuDemangler ClassCastException when parsing a <code>typeinfo</code> string containing <code>operator</code> text. (GP-160, Issue #1870, #2267)</li>
<li><I>Demangler</I>. Added <B>stdlib.h</B> include to the GNU Demangler to fix a build issue on some systems. (GP-187, Issue #2294)</li>
<li><I>DWARF</I>. Corrected DWARF relocation handling where the address image base adjustment was factored in twice. (GT-3330)</li>
<li><I>File Formats</I>. Fixed a potential divide-by-zero exception in the EXT4 file system. (GT-3400, Issue #1342)</li>
<li><I>File Formats</I>. Fixed date and time parsing of dates in cdrom <code>iso9660</code> image files. (GT-3451, Issue #1403)</li>
<li><I>Graphing</I>. Fixed a ClassCastException sometimes encountered when performing <B>Select -> Scoped Flow -> Forward Scoped Flow</B>. (GP-180)</li>
<li><I>GUI</I>. Fixed inconsistent behavior with the interactive python interpreter's key bindings. (GT-3282)</li>
<li><I>GUI</I>. Fixed Structure Editor bug that prevented the <B>F2 Edit</B> action from editing the correct table cell after using the arrow keys. (GT-3308, Issue #703)</li>
<li><I>GUI</I>. Updated the Structure Editor so the <B>Delete</B> action is put into a background task to prevent the UI from locking. (GT-3352)</li>
<li><I>GUI</I>. Fixed IndexOutOfBoundsException when invoking column filter on Key Bindings table. (GT-3445)</li>
<li><I>GUI</I>. Fixed the analysis log dialog to not consume all available screen space. (GT-3610)</li>
<li><I>GUI</I>. Fixed issue where <B>Location</B> column, when used in the column filters, resulted in extraneous dialogs popping up. (GT-3623)</li>
<li><I>GUI</I>. Fixed Data Type Preview <B>copy</B> action so that newlines are preserved; updated table export to CSV to escape quotes and commas. (GT-3624)</li>
<li><I>GUI</I>. Fixed tables in Ghidra to copy the text that is rendered. Some tables mistakenly copied the wrong value, such as the Functions Table's Function Signature Column. (GT-3629, Issue #1628)</li>
<li><I>GUI</I>. Structure editor name now updates in title bar and tab when structure is renamed. (GP-19)</li>
<li><I>GUI</I>. 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)</li>
<li><I>GUI</I>. 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)</li>

<li><I>GUI</I>. Fixed a bug that caused Call Tree nodes to go missing when showing more than one function with the same name. (GP-213, Issue #1682)</li>
<li><I>GUI:Project Window</I>. Fixed Front End <B>copy</B> action to allow for the copy of program names so that users can paste those names into external applications. (GT-3403, Issue #1257)</li>
<li><I>Headless</I>. Headless Ghidra now properly honors the <code><B>-processor</B></code> flag, even if the specified processor is not a valid <B>opinion</B>. (GT-3376, Issue #1311)</li>
