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.
What is SimpleSAMLphp?
Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.
SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both whenever a fix lands. The August sequence is representative: a 2.4.9 bugfix, a coordinated 2.5.3 security drop re-tagged hours later as 2.5.3.1, and now a 2.4.10 bugfix closing the month on the older branch. Release bodies carry no changelog text at all, just a download link, an upgrade-notes pointer and SHA256 checksums, so the feed tells operators when to patch but never what changed.

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.
SimpleSAMLphp
5.0DEVOPS
Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.
◆ Current state
SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both whenever a fix lands. The August sequence is representative: a 2.4.9 bugfix, a coordinated 2.5.3 security drop re-tagged hours later as 2.5.3.1, and now a 2.4.10 bugfix closing the month on the older branch. Release bodies carry no changelog text at all, just a download link, an upgrade-notes pointer and SHA256 checksums, so the feed tells operators when to patch but never what changed.
◆ Where it's heading
This is maintenance cadence, not product development, and the shape of it is stable enough to predict. Security issues get simultaneous twin tags across both supported branches; everything else lands as a branch-local bugfix point, alternating between 2.4 and 2.5 every few weeks. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories — the exception that shows the notes could carry detail and normally do not.
◆ Prediction
Expect the alternation to continue, with the next paired 2.4.x and 2.5.x tags arriving together whenever an advisory lands and content again deferred to the external changelog.
