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 Liquidsoap?

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

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.

L6.3

Liquidsoap opens its 2.5 line with subtitles as a first-class content type and a streaming server of its own

◆ Current state

The 2.5.x rolling release carries the accumulated 2.5.0 changelog, and it is the largest body of work Liquidsoap has staged in over a year. Subtitles become a dedicated content type alongside audio and video, with native SRT decoding, FFmpeg subtitle encode and decode, bitmap passthrough, callbacks, transformations and dynamic insertion. An Icecast-compatible server ships as icecast.server, with source authentication, mount points, relay and per-listener encoding. Underneath, the source composition model was rewritten: switch, fallback, rotate and random drop their parallel list parameters for per-source methods, and switching now fades by default.

◆ Where it's heading

Liquidsoap is expanding on two axes at once. It is broadening what a stream can carry - subtitles are a third content modality in a system that has understood two - and it is moving up the stack from a source that feeds Icecast into something that can be the Icecast. The language work points the same way: a source(_) type for unknown content, callback release semantics, and effect-scoped clocks are the kind of changes made when scripts are getting large enough that lifetime and typing errors cost real production time.

◆ Prediction

The 2.5.0 final should follow the rolling branch within a release cycle, and the migration guide already shipped for the composition parameter changes suggests the breaking surface is considered settled. Watch whether subtitle support reaches the harbor and Icecast server paths, which the current notes do not say.
