- No engine version upgrade in this maintenance release.
Features
- PgBouncer updated from version 1.22 to 1.23. Admin console queries now include extra columns with this update.
- Citus 13.2 set as the default for PG16 and PG17 for all new Elastic Cluster provisions.
- Enabled the query store extension for PG18.
- pg_squeeze extension upgraded to version 1.9, resolving a critical bug in the
squeeze.squeeze_table()function that could lead to data corruption. - IP4R extension enabled.
- TimescaleDB extension upgraded to version 2.22.0.
Known issues fixed
- Fixed an issue that could leave a server in a failed state after a user attempts a Start operation multiple times in a region experiencing capacity constraints. The server is now deallocated in these situations, and a capacity-related error message is returned to the user. This fix now enables users to reattempt Start operations without the server entering a failed state.
