Fiber vs Mapnik: at a glance
What is Fiber?
Fiber marks its v2 module deprecated in favour of v3
Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.
What is Mapnik?
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.

Fiber marks its v2 module deprecated in favour of v3
◆ Current state
Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.
◆ Where it's heading
The deprecation notice tells v2 users to plan their move. With v2 patches shrinking to one or two pull requests, active development sits entirely on v3.
◆ Prediction
Further v2 releases are likely to be security fixes only; the feed does not show v3's current state past rc.3.
Mapnik
0.0DEVOPS
Mapnik 4.3.2 is a performance release from one contributor, with line dash fixes.
◆ 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.
