+== Release 8.0.3 (August 2026)
+
+Couchbase Server 8.0.3 was released in August 2026.
+This maintenance release contains fixes for issues listed below.
+
+=== Fixed Issues
+{empty}
+
+==== Cluster Manager
+
+link:https://jira.issues.couchbase.com/browse/MB-72097[MB-72097]::
+This fix prevents a critical bug where undefined bucket storage properties caused incorrect transitions to Magma during upgrades.
+The issue affected buckets created before version 5.0.0.
+
+link:https://jira.issues.couchbase.com/browse/MB-70951[MB-70951]::
+The `/metrics` REST API previously reported certain low cardinality statistics twice.
+This update ensures each statistic appears only once in the output.
+
+==== Data Service
+
+link:https://jira.issues.couchbase.com/browse/MB-70640[MB-70640]::
+This fix addresses a rebalance hang observed during node scaling and swap rebalance operations.
+The issue was related to socket receive buffer management on specific Linux kernels.
+
+==== Analytics Service
+
+link:https://jira.issues.couchbase.com/browse/MB-71453[MB-71453]::
+Queries combining LIMIT with index-nested-loop joins could return incorrect results.
+The fix ensures all filter conditions are evaluated before applying the limit.
+
+==== XDCR
+
+link:https://jira.issues.couchbase.com/browse/MB-72305[MB-72305]::
+Upgraded nodes now correctly handle rebalancing when replications or buckets were deleted and recreated.
+This prevents issues with stale manifests and incomplete backfills.
+
+link:https://jira.issues.couchbase.com/browse/MB-71586[MB-71586]::
+The new `forwardLocalOnly` setting allows XDCR to replicate only local mutations.
+This feature reduces data transfer by identifying mutations originating from source clusters.
+
+link:https://jira.issues.couchbase.com/browse/MB-71257[MB-71257]::
+A race condition causing deadlocks during replication pause or deletion has been resolved.
+The fix ensures goroutines exit properly during rollback operations.
+
+link:https://jira.issues.couchbase.com/browse/MB-71013[MB-71013]::
+XDCR now correctly handles conflict resolution for locked documents on target clusters.
+This fix prevents unnecessary skipping of mutations and potential data loss.
+
+==== Tools
+
+link:https://jira.issues.couchbase.com/browse/MB-70745[MB-70745]::
+Restore operations no longer fail when Cost-Based Optimizer statistics contain keys with double colons.
+This fix applies to indexes using specific string functions.
