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 Rivet?

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

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.

7.5

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆ Current state

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

◆ Where it's heading

Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.

◆ Prediction

Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
