+# Percona Distribution for PostgreSQL 15.16 ({{date.15_16}})
+
+[Installation](installing.md){.md-button}
+
+--8<-- "release-notes-intro.md"
+
+This release of Percona Distribution for PostgreSQL is based on [PostgreSQL 15.16](https://www.postgresql.org/docs/current/release-15-16.html).
+
+!!! important PostgreSQL RPMs rebuilt to disable debug assertions
+
+ The Percona Server for PostgreSQL (PSP) and Percona Distribution for PostgreSQL (PPG) RPM packages for **PostgreSQL versions 13 through 18 released as part of the Q3 and Q4 quarterly release** were built with debug assertions enabled (`--enable-cassert`).
+
+ If you installed or updated PostgreSQL RPMs within the last four months, you may suffer performance degradation: 18.1, 17.6, 17.7, 16.10, 16.11, 15.14, 15.15, 14.19, 14.20, 13.22, 13.23.
+
+ These packages have been rebuilt, and all users running RPM-based installations of the affected releases are **strongly advised** to update to the latest available packages.
+
+ To verify, run `pg_config --configure`. If the output includes `--enable-cassert`, then your installation is affected.
+
+## Release Highlights
+
+### Percona Telemetry Extension for PostgreSQL Deprecated
+
+The `percona_pg_telemetry` extension has been deprecated and replaced with a backwards compatibility stub to avoid breaking existing installations.
+
+No telemetry data will be gathered, it will not be maintained going forward and it should not be used in new deployments.
+
+### Tarball updates
+
+The [installation preconditions for tarballs](tarball.md) now include an extra step for RHEL, Rocky Linux, or Oracle Linux 10: installing the `acl` package.
+
+The binary tarballs for x86_64 and ARM64 architectures have been updated in this release. The following libraries and components have new versions:
+
+- pgbouncer: 1.25.0
+- pgpool2: 4.6.3
+- etcd: 3.5.24
+- PostGIS: 3.5.4
+- set_user: 4.2.0
+- pg_repack: 1.5.3
+- pg_stat_monitor: 2.3.1
+- pgBackRest: 2.57.0
+- Patroni: 4.1.0
+- HAProxy: 2.8.16
+- pgvector: 0.8.1
+- libxml2: 2.12.10
+
+See [Install Percona Distribution for PostgreSQL from binary tarballs](tarball.md) for the download links.
+
+The [installation preconditions for tarballs](tarball.md) now include an extra step for RHEL, Rocky Linux, or Oracle Linux 10: installing the `acl` package.
+
+### Addressed CVEs
+
+This release includes important security measures that address the following CVEs: CVE-2025-12817, CVE-2025-12818. For more details, see the PostgreSQL [15.15 release notes](https://www.postgresql.org/docs/15/release-15-16.html).
+
+## Known Issue
+
+### For minor & major upgrades (RHEL only)
+
+During an upgrade on RHEL, you may encounter the following error:
+
+```
+Unknown Error occurred: Transaction test error:
+ file /usr/share/postgresql-common/server/postgresql.mk from install of percona-postgresql-common conflicts with file from package percona-postgresql-common-dev
+ file /usr/share/postgresql-common/t/040_upgrade.t from install of percona-postgresql-common conflicts with file from package percona-postgresql-common-dev
+```
+
+To resolve this, remove the `percona-postgresql-common-dev` package and reinstall it with the new intended upgraded PPG/PSP server.
