+The PostgreSQL Global Development Group has released an update to all supported
+versions of PostgreSQL, including 17.2, 16.6, 15.10, 14.15, and 13.18.
+Additionally, due to the nature of one of the issues in the
+[previous update release](https://www.postgresql.org/about/news/out-of-cycle-release-scheduled-for-november-21-2024-2958/),
+the PostgreSQL GLobal Development Group is also releasing a 12.22 release for
+PostgreSQL 12. PostgreSQL 12 is now EOL and will not receive more fixes.
+
+For the full list of changes, please review the
+[release notes](https://www.postgresql.org/docs/release/).
+
+PostgreSQL 12 EOL Notice
+------------------------
+
+**This is the final release of PostgreSQL 12**. PostgreSQL 12 is now end-of-life
+and will no longer receive security and bug fixes. If you are
+running PostgreSQL 12 in a production environment, we suggest that you make
+plans to upgrade to a newer, supported version of PostgreSQL. Please see our
+[versioning policy](https://www.postgresql.org/support/versioning/) for more
+information.
+
+Bug Fixes and Improvements
+--------------------------
+ 
+The issues listed below affect PostgreSQL 17. Some of these issues may also
+affect other supported versions of PostgreSQL.
+
+* Restore functionality of [`ALTER ROLE .. SET ROLE`](https://www.postgresql.org/docs/current/sql-alterrole.html)
+and [`ALTER DATABASE .. SET ROLE`](https://www.postgresql.org/docs/current/sql-alterdatabase.html).
+The fix for [CVE-2024-10978](https://www.postgresql.org/support/security/CVE-2024-10978/)
+accidentally caused settings for role to not be applied if they came from
+non-interactive sources, including previous `ALTER {ROLE|DATABASE}` commands and
+the [`PGOPTIONS`](https://www.postgresql.org/docs/current/libpq-envars.html)
+environment variable.
+* Repair ABI break for extensions that work with `struct ResultRelInfo`,
+such as `timescaledb`. This fix restores the affected structure to its previous
+size, so that such extensions don't need to be rebuilt.
+* Fix cases where a logical replication slot's `restart_lsn` could go backwards.
+* Avoid deleting still-needed WAL files during
+[`pg_rewind`](https://www.postgresql.org/docs/current/app-pgrewind.html).
+* Fix race conditions associated with dropping shared statistics entries, which
+could lead to loss of statistics data.
+* Fix crash with `ALTER TABLE` when checking to see if an index's opclass
+options have changed if the table has an index with a non-default operator
+class.
+
+Updating
+--------
+
+All PostgreSQL update releases are cumulative. As with other minor releases,
+users are not required to dump and reload their database or use `pg_upgrade` in
+order to apply this update release; you may simply shutdown PostgreSQL and
+update its binaries.
+
+Users who have skipped one or more update releases may need to run additional
+post-update steps; please see the release notes from earlier versions for
+details.
+
+For more details, please see the
+[release notes](https://www.postgresql.org/docs/release/).
