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