NATS

DEVOPS
Velocity5.0

High-performance messaging system for distributed applications

nats.io ↗

NATS keeps two release lines in lockstep while slowly widening multi-tenant routing controls.

messagingjetstreammulti-tenancysecurity-patchesrelease-maintenance
◆Current state
NATS maintains 2.14 and 2.15 in parallel, shipping matching patch and RC releases on both. The latest RCs add account-hash subject mapping functions and a new TLS verification option, while the October patches were mostly Go toolchain bumps carrying a certificate-trust CVE mitigation.
◆Where it's heading
The project is in a stabilization phase: JetStream placement limits, gateway compatibility and security patches dominate. The new account-hash mapping functions are the only feature thread, aimed at operators running many isolated accounts and leafnodes.
◆Prediction
Expect 2.15.3 and 2.14.10 to go final with the account-hash mapping functions, followed by more JetStream placement and limit fixes.
