About NATS
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
