What is Apache OpenNLP?

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

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.

Apache OpenNLP vs Mapnik: editorial side-by-side

A5.0

Apache OpenNLP ships 3.0.0 final, closing a milestone track that ran since spring.

◆ Current state

Apache OpenNLP runs three release lines: 1.9.x for Lucene and Solr 8 users, 2.5.x as the stable line, and the 3.0 track that went through six milestones. On 12 November the project tagged 3.0.0 final alongside a 2.5.13 patch, again shipping both lines on the same day. The tags carry no release notes in the feed, so what changed since 3.0.0-M6 is not visible here.

◆ Where it's heading

The 3.0 milestones combined security hardening (deserialization and XXE fixes, model-loading allowlists) with new text tooling such as the Unicode normalization engine and a SymSpell spell checker, while 2.5.x added RoBERTa inference through ONNX Runtime. With 3.0.0 out, the 2.5 line is likely to move to backports only, and new work should land on 3.x.

◆ Prediction

Expect a 3.0.1 patch and continued 2.5.x security backports; whether 1.9.x gets further releases is unclear from these entries.

0.0

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.
