+## 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.
+
+#### Breaking Changes
+
+- Reworked datasource plugin system. Plugins now need to implement a class with the macros in `datasource_plugin.hpp` ([#4291](https://github.com/mapnik/mapnik/pull/4291))
+- mapnik now has a global `mapnik::setup()` method which have to be called before any other functions of mapnik. Defined in `mapnik.hpp`. Currently there is a auto setup functionality. It can be disabled using the cmake option `DISABLE_MAPNIK_AUTOSETUP=ON`. Note: In order not to insert this change into every code base, it is currently still called during the dynamic initialisation time. However, if mapnik is compiled statically, this function must be called.  ([#4291](https://github.com/mapnik/mapnik/pull/4291))

 - Slightly improved `sql_utils::table_from_sql` ([2587bb3](https://github.com/mapnik/mapnik/commit/2587bb3a1d8db397acfa8dcc2d332da3a8a9399f))
 - Added wrappers for proper quoting in SQL query construction: `sql_utils::identifier`, `sql_utils::literal` ([7b21713](https://github.com/mapnik/mapnik/commit/7b217133e2749b82c2638551045c4edbece15086))
 - Added two-argument `sql_utils::unquote`, `sql_utils::unquote_copy` that also collapse inner quotes ([a4e8ea2](https://github.com/mapnik/mapnik/commit/a4e8ea21be297d89bbf36ba594d6c661a7a9ac81))
