@@ -5,6 +5,29 @@ All notable changes to mcilspy will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Calendar Versioning](https://calver.org/) for major releases.
 
+## [0.4.0] - 2026-02-11
+
+### Added
+- **PDB Generation** (`generate_pdb` flag) - Generate portable PDB files from decompiled assemblies for IDE debugging
+- **PDB Variable Names** (`use_pdb_variable_names` flag) - Use original variable names from existing PDB files for improved readability
+- **`dump_package` tool** - Extract all assemblies from NuGet package folder structures for bulk analysis
+
+### Changed
+- `decompile_assembly` now exposes all ilspycmd CLI options - mcilspy has 100% feature coverage
+- Updated documentation with new tool and parameter descriptions
+- Tool count increased from 14 to 15
+
+## [0.3.0] - 2026-02-10
+
+### Fixed
+- **Type parsing regex** - Fixed `list_types` returning empty results (regex expected "Class:" but ilspycmd outputs "Class ")
+- **UserStringHeap data access** - Fixed Python name mangling issue in `search_strings` causing crash
+- **Decompile stdout mode** - Added `_decompile_to_stdout()` method for simple decompilation without output directory
+
+### Changed
+- Merged comprehensive code review fixes from parallel taskmaster branches (security, architecture, performance, testing)
+- All 165 tests passing
+
