+# Changelog
+
+## v2.1.2
+
+- Improved type deduplication algorithm (stdump v1.1 is included).
+- Improved logic for handling nested types and type conflicts.
+- The STABS analyzer will now only run once by default to prevent accidental corruption of files.
+
+## v2.1.1
+
+- Added support for Ghidra 10.2.3.
+
+## v2.1.0
+
+- A STABS symbol table analyzer is included which makes use a bundled copy of [stdump](https://github.com/chaoticgd/ccc) to extract information about data types, functions and global variables from ELF files with a .mdebug section.
+- Simplified the pcode implementation of the plzcw instruction.
+
+## v2.0.0
+
+- Support for Ghidra 10.2.2.
+- The VU macro and MMI instruction implementations have	been replaced with pcodeop stubs, improving decompilation.
+- Support for disassembling VU microcode has been removed. If you want to reverse a VU microprogram may I suggest having a look at [vutrace](https://github.com/chaoticgd/vutrace).

 # Ghidra Emotion Engine: Reloaded [![run tests](https://github.com/chaoticgd/ghidra-emotionengine-reloaded/actions/workflows/test.yml/badge.svg?branch=main)](https://github.com/chaoticgd/ghidra-emotionengine-reloaded/actions/workflows/test.yml)
 An extension for Ghidra that adds support for the PlayStation 2.
 
-The core MIPS/FPU/COP0 instruction are based off the MIPS32/64 processor included in Ghidra, with superfluous instructions stripped out and some instructions modified.
+This extension is based on the original [ghidra-emotionengine](https://github.com/beardypig/ghidra-emotionengine) project, with a number or changes.
 
-The following instuction sets are currently supported:
+## Features
 
- 1. The core MIPS instruction set
- 2. The EE core instruction set (MMI, etc)
- 3. COP0 (System control processor) instruction set
- 4. COP1 (FPU) instruction set
- 5. COP2 (VU0) macro instruction set
-
-This extension is based on the original [ghidra-emotionengine](https://github.com/beardypig/ghidra-emotionengine) project, with a number or changes:
+- Disassemble and decompile EE-specific instruction sets (MMI, VU0 macro mode, etc).
+- Recover data types, functions and global variables from ELF files with `.mdebug` sections with the included STABS Analyzer.
+- Import PCSX2 save states.
+- Fix references to global variables with the MIPS-R5900 Constant Reference Analyzer.
 - Support for Ghidra 10.2.3.
-- The VU macro and MMI instruction implementations have	been replaced with pcodeop stubs. This is a bit subjective, but I think it helps a lot.
-- Support for disassembling VU microcode has been removed. If you want to reverse a VU microprogram may I suggest having a look at [vutrace](https://github.com/chaoticgd/vutrace).
