What is Argo CD?
Argo CD is on RC4 of v3.4 while patching three live minor branches in parallel — disciplined maintenance posture.
Argo CD's recent activity is a textbook mature-OSS release pattern: v3.4.0 advancing through release candidates (RC1 mid-March, RC4 by March 27) while v3.1, v3.2, and v3.3 receive simultaneous patch releases. The 3.3.6, 3.3.5, and 3.3.4 patches are predominantly cherry-pick bug fixes from main — controller diff-detection corrections, cache installation-id fixes. v3.4.0-rc1 introduced real feature work (e.g., a Health field on ApplicationSet status); subsequent RCs are stabilization passes.
What is Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

Argo CD
0.0DEVOPS
Argo CD is on RC4 of v3.4 while patching three live minor branches in parallel — disciplined maintenance posture.
◆ Current state
Argo CD's recent activity is a textbook mature-OSS release pattern: v3.4.0 advancing through release candidates (RC1 mid-March, RC4 by March 27) while v3.1, v3.2, and v3.3 receive simultaneous patch releases. The 3.3.6, 3.3.5, and 3.3.4 patches are predominantly cherry-pick bug fixes from main — controller diff-detection corrections, cache installation-id fixes. v3.4.0-rc1 introduced real feature work (e.g., a Health field on ApplicationSet status); subsequent RCs are stabilization passes.
◆ Where it's heading
Argo CD is steady-stating as the de-facto Kubernetes GitOps controller with the disciplined release cadence of a CNCF graduated project. Multi-branch maintenance signals strong enterprise install-base support — operators pin to specific minors and won't accept being forced onto a new line. The 3.4.0 RC progression (RC1 → RC4 in two weeks) suggests careful enterprise-quality stabilization rather than feature scope-creep.
◆ Prediction
v3.4.0 GA likely lands within 2-4 weeks based on the RC cadence and lack of major late-cycle changes visible. Expect the 3.3.x line to keep receiving security and bug backports for several months after 3.4 GA, while 3.1.x continues as the longest-tail patch line.
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
