+## Mapnik 4.0.3
 
-## UNRELEASED
+Released October 30th, 2024
+
+(Packaged from [05389e3c7](https://github.com/mapnik/mapnik/commit/05389e3c7))
+
+- Remove 'final' specifier from invalid_featureset implementation
+  (issues with dynamic_cast<> when building using Apple clang version 16.0.0 on darwin-arm64)
+- Rename invalid_featureset to empty_featureset
+- Upgrade to SCons v4.8.1
+- Fix unit tests e.g  #endif statement (via @bgardner-noggin)
+
+## Mapnik 4.0.2
+
+Released August 21st, 2024
+
+- CMake build - set `SOVERSION` to `${MAPNIK_MAJOR_VERSION}.${MAPNIK_MINOR_VERSION}`
+- Upgraded SCons build system to v4.8.0
+
+## Mapnik 4.0.1
+
+- Use CMAKE_INSTALL_LIBDIR for libdir in pkg-config files
+- Support gcc 14
+- Improved accuracy of bounding box re-projections. Automatic spliting at (0, 0) and merging results.
+- Fixes missing features when using WGS 84 / Arctic Polar Stereographic (`epsg:4326 <-> epsg:3995`)
+- Added `area_of_use` method to `mapnik::projection`
+
+## Mapnik 4.0.0
 
 #### Notice
 
-- Mapnik now requires C++14 compliant compiler (`-std=c++14`)
+- Mapnik now requires C++17 compliant compiler (`-std=c++17`)
 - Mapnik now supports CMake as a build system. See [#4191](https://github.com/mapnik/mapnik/pull/4191) and the [docs](https://github.com/mapnik/mapnik/blob/master/docs/cmake-usage.md) for more info.
