+summary: The CloudNativePG community has released new updates for the 1.28 and 1.27 versions of the CloudNativePG operator.
+---
+
+The **CloudNativePG Community** is pleased to announce the release of
+**CloudNativePG Operator** versions 1.28.1 and 1.27.3.
+
+These releases deliver important bug fixes and stability improvements, ensuring
+your PostgreSQL clusters continue to run reliably in production environments.
+We recommend all users upgrade at their earliest convenience, particularly
+those using PgBouncer or managing replica clusters.
+
+Specifically, these updates address several critical scenarios that directly
+impact production reliability:
+
+- **Critical fix for PgBouncer upgrades**: We resolved an issue where stale TLS
+  status fields in the `Pooler` were not correctly cleared. This was
+  particularly disruptive for users upgrading to version 1.28, as it could cause
+  PgBouncer to use incorrect certificates, resulting in "unsupported certificate"
+  errors and blocking all application connectivity.
+
+- **Timeline protection during WAL restore**: Improved the WAL restore logic to
+  prevent replicas from downloading timeline history files with IDs greater
+  than the cluster's current timeline. This prevents recovery failures caused by
+  incomplete promotion attempts, where PostgreSQL creates history files for
+  timelines that the cluster never officially adopts.
+
+- **Timeline reset after major upgrades**: We addressed a critical issue in the
+  major version upgrade path. After a `pg_upgrade`, the operator now correctly
+  resets the `TimelineID` to 1. This prevents replicas from attempting to follow
+  an incompatible timeline from the previous major version, which formerly led to
+  fatal recovery errors.
