What is GRASS GIS?

GRASS dropped the GIS from its name and gave Python users a real API.

GRASS 8.5.0 landed in May 2026 with more than 2,570 changes since 8.4.2, a rebrand from GRASS GIS to GRASS with a new logo, and documentation rewritten in Markdown under MkDocs. The headline technical change is grass.tools, a Python API that calls GRASS tools as functions with direct NumPy array and raster pack I/O. Parallelisation was extended across r.mapcalc, r.texture, r.horizon and v.surf.rst, and JSON output now covers dozens of tools.

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.

GRASS dropped the GIS from its name and gave Python users a real API.

◆ Current state

GRASS 8.5.0 landed in May 2026 with more than 2,570 changes since 8.4.2, a rebrand from GRASS GIS to GRASS with a new logo, and documentation rewritten in Markdown under MkDocs. The headline technical change is grass.tools, a Python API that calls GRASS tools as functions with direct NumPy array and raster pack I/O. Parallelisation was extended across r.mapcalc, r.texture, r.horizon and v.surf.rst, and JSON output now covers dozens of tools.

◆ Where it's heading

GRASS has spent three releases making itself scriptable from outside its own shell. 8.4.0 renamed location to project and started the JSON output push; 8.4.1 and 8.4.2 broadened it; 8.5.0 finished the job with a first-class Python entry point and expanded grass.jupyter with interactive region updates and parallelised time-series maps. A forty-year-old command-line GIS is repositioning as a library that Python data workflows import.

◆ Prediction

With grass.tools established, expect the next cycle to extend JSON output and direct array I/O to the tools that still require file round-trips.

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.
