Mapnik 4.3.2 is a performance release from one contributor, with line dash fixes.

map-renderingperformancevector-tilescppgeospatial
◆Current state
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.
◆Where it's heading
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.
◆Prediction
Expect another 4.3.x point release with further performance work; a 4.4 feature line is not visible in the entries.

    Mapnik 4.3.2: faster rendering, SVG pattern cache, dash offset fix

    Further performance changes, cached SVG polygon patterns and correct line dash offsets in both renderers make 4.3.2 a speed and correctness release. It continues the post-4.3.0 cleanup, again with a revert-and-redo on one fix.

    Mapnik 4.3.1 reworks font fallback and enables NDEBUG by default

    A corrective point release: 4.3.0's multi-font Unicode fix was patched, the patch reverted, and a separate font-fallback change landed in its place. NDEBUG on by default strips assertions from stock builds, which together with the unspecified performance work makes this a speed-and-text-rendering release.

    Mapnik 4.3.0 fixes PostGIS pool churn and multi-font Unicode runs

    The release 4.3.1 corrects. Brought PostGIS async connection pooling under control, added an unbuffered bbox variable, finished the boost::optional removal, and made the first attempt at shaping complex Unicode across a fontset. Three first-time contributors landed here.

    Mapnik 4.2.1 makes the plug-in infrastructure more flexible

    Part of the generalization of the datasource layer, loosening how input plugins are registered and combined so tile sources can sit beside the established PostGIS and GDAL inputs.

    Mapnik 4.2.0 combines the input plugins

    Consolidated the separate input plugins into a combined build, the structural step that the later plugin-infrastructure work builds on.
