+### Breaking Changes
+- **Binary Renaming**: Renamed all binaries from `privatebinapi.*` to `libprivatebin.*`
+  - `privatebinapi.dll` → `libprivatebin.dll`
+  - `privatebinapi.lib` → `libprivatebin.lib`
+  - `privatebinapi.exp` → `libprivatebin.exp`
+- **Header Renaming**: Renamed main header file from `privatebinapi.h` to `libprivatebin.h`
+- **Source Renaming**: Renamed main source file from `privatebinapi.cpp` to `libprivatebin.cpp`
+
+### Project Restructuring
+- **Project Name**: Changed from `PrivateBinAPI` to `LibPrivateBin`
+- **Target Names**: Updated all CMake targets to use `libprivatebin` naming convention
+- **Include Paths**: Updated all include statements throughout the codebase
+- **Build Scripts**: Updated all build and release scripts to reference new binary names
+
+### Technical Improvements
+- **Consistent Naming**: Unified naming convention across all project components
+- **Build System**: Updated CMakeLists.txt files in main project, examples, and tests
+- **Script Updates**: All PowerShell scripts updated to handle new binary names
+- **Documentation**: Updated README.md examples with new include paths
+
+### Compatibility Notes
+- **API Compatibility**: No functional changes to the API - only naming changes
+- **Source Code**: Existing code using the old names will need to be updated
