What is Groonga?
A new minor line opens on nothing but a crash fix.
Groonga releases every few weeks, alternating between small additions to its query-language surface and packaging repair. The functional work in this window is narrow and concrete: a string_truncate() function with omission-mark handling, between() accepting vector values though without index support, and a prefix option on language_model_vectorize(). The rest is distribution upkeep — Ubuntu 26.04 support, an ODR fix that unblocks LTO builds, and two attempts at restoring a missing Windows runtime DLL.
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.

Groonga
5.0DEVOPS
A new minor line opens on nothing but a crash fix.
◆ Current state
Groonga releases every few weeks, alternating between small additions to its query-language surface and packaging repair. The functional work in this window is narrow and concrete: a string_truncate() function with omission-mark handling, between() accepting vector values though without index support, and a prefix option on language_model_vectorize(). The rest is distribution upkeep — Ubuntu 26.04 support, an ODR fix that unblocks LTO builds, and two attempts at restoring a missing Windows runtime DLL.
◆ Where it's heading
Two tracks run in parallel: incremental function additions for query authors, and the unglamorous work of keeping binaries correct across platforms. The one thread pointing beyond classic full-text search is language_model_vectorize(), but it moved once and only to gain an option. The jump to 16.1.0 carrying only a fix suggests the version number tracks branch policy rather than the size of the change.
◆ Prediction
Expect point releases along the 16.1.x line, with the next functional change most likely another scalar or vector function refinement. Nothing in these entries supports predicting a shift in Groonga's indexing architecture.
Rivet
7.5DEVOPS
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.
