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 Groonga?

A veteran full-text engine quietly growing embedding functions alongside its string toolkit.

Groonga ships small, precise releases roughly monthly, each documenting changes with runnable examples and crediting the reporter by name. The 16.0 line opened in February 2026 with an annual major release that deliberately carried no backward-incompatible changes. Recent work splits between conventional search functions — a new string_truncate(), vector support in between() — and a language model path where language_model_vectorize() consumes GGUF models from HuggingFace and TokenLanguageModelKNN handles query and passage prefixes. Contributor counts per release run to a handful of people.

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.

5.0

A veteran full-text engine quietly growing embedding functions alongside its string toolkit.

◆ Current state

Groonga ships small, precise releases roughly monthly, each documenting changes with runnable examples and crediting the reporter by name. The 16.0 line opened in February 2026 with an annual major release that deliberately carried no backward-incompatible changes. Recent work splits between conventional search functions — a new string_truncate(), vector support in between() — and a language model path where language_model_vectorize() consumes GGUF models from HuggingFace and TokenLanguageModelKNN handles query and passage prefixes. Contributor counts per release run to a handful of people.

◆ Where it's heading

The embedding functions are the notable thread. A search engine of this vintage adding model-backed vectorization as ordinary functions, callable from the same query language as everything else, is positioning for hybrid retrieval without a separate vector store in the stack. The rest of the cadence is characteristic of the project: careful compatibility work, Windows packaging problems chased across multiple releases, and build-system fixes contributed by downstream packagers.

◆ Prediction

Expect indexing support for the vector cases that currently work without an index — between() on vectors is explicitly flagged as unindexed — and further options on the language model functions. The project's no-breaking-changes stance on major releases suggests continuity rather than a rearchitecture.
