What is NATS?
NATS second release candidates add a config reload check and faster redelivery queues.
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.
What is Rivet?
Rivet's Rust SDK for Actors is generally available.
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
NATS vs Rivet: editorial side-by-side
NATS
5.0DEVOPS
NATS second release candidates add a config reload check and faster redelivery queues.
◆ Current state
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.
◆ Where it's heading
The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.
◆ Prediction
Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
Rivet
6.3DEVOPS
Rivet's Rust SDK for Actors is generally available.
◆ Current state
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
◆ Where it's heading
Rivet is widening who can build on its actor model while 3.0 matures: a Rust SDK GA lets performance-sensitive teams use it without a TypeScript layer. The platform direction remains S3-only infrastructure for stateful workloads.
◆ Prediction
Expect 3.0 to move toward a stable release and more SDK languages. The entries don't show a 3.0 GA date.
