+## Release 2.1.2
+
+_September 25, 2025_
+
+BUG FIXES:
+
+- Fixes a bug where the subscribe method was incorrectly intercepting initial configuration operations after a ServiceAccountToken rotation and signaling broadcast completion. [3905](https://github.com/nginx/nginx-gateway-fabric/pull/3905)
+- Fixes an issue where a failed configuration reload caused all HTTPRoutes to be marked as invalid (Accepted: false). This led to external-dns removing DNS records even though the configuration had been rolled back. Routes now retain their valid state during reload failures, preventing unnecessary DNS disruptions. [3936](https://github.com/nginx/nginx-gateway-fabric/pull/3936)
+- Adds NGINX image version validation during agent connections to prevent newer config being sent to pods running previous image versions during upgrades. [3928](https://github.com/nginx/nginx-gateway-fabric/pull/3928)
+
+NGINX AGENT BUG FIXES:
+
+- The NGINX Agent v3.3.1 update fixes connection reset issues during config apply by reusing existing connections, adds rollback on failures, and improves logging for more reliable configuration updates. [1261](https://github.com/nginx/agent/pull/1261)
+
