Sonic yanks two releases in a day, then ships faster ingest and new count commands.
A side-by-side editorial comparison of Mapnik and OpenAPI Generator — release velocity, themes, recent moves, and the top alternatives to consider.
Mapnik 4.3.2 is a performance release from one contributor, with line dash fixes.
Mapnik ships small point releases with a growing set of outside contributors. 4.3.2 on September 23 is mostly one contributor's work: more performance changes, cached rasterized SVG polygon patterns, a GeoJSON fix and line dash offsets honored in both the AGG and Cairo renderers. A marker-dimension fix was merged, reverted and merged again in a corrected form, the same pattern as the font fix in 4.3.1.
OpenAPI Generator keeps a 240-change release cadence across dozens of languages
OpenAPI Generator ships stable releases every few weeks to two months, each with 150 to 240 changes across generators for C#, C++, Go, Java, Kotlin, Dart and many more. 7.26.0 fixes nullable allOf handling in OpenAPI 3.1, exposes schema tracking in the Gradle plugin, adds .NET 10 support for aspnetcore and a Boost.Beast HTTP/1.1 server generator for C++. 7.25.0 before it added vendor override injection and splitOperationsByContentType.

Recent releases have turned from new data sources, such as remote PMTiles in 4.1.3, toward render speed and correctness. CI now runs on pull requests and forks, which makes outside contributions easier to land.
Expect another 4.3.x point release with further performance work; a 4.4 feature line is not visible in the entries.

The core keeps absorbing OpenAPI 3.1 semantics while each language generator takes fixes from its own maintainers. New generators and framework versions arrive steadily, and breaking changes ship with fallbacks.
OpenAPI 3.1 normalisation fixes have appeared in every recent release, so expect them in the next one too.
