+# Percona Distribution for PostgreSQL 16.4 ({{date.16_4}})
+
+[Installation](installing.md){.md-button}
+
+--8<-- "release-notes-intro.md"
+
+This release of Percona Distribution for PostgreSQL is based on [PostgreSQL 16.4](https://www.postgresql.org/docs/16/release-16-4.html). 
+
+## Release Highlights
+
+* This release of Percona Distribution for PostgreSQL fixes security vulnerability [CVE-2024-7348](https://nvd.nist.gov/vuln/detail/CVE-2024-7348). 
+
+* Percona Distribution for PostgreSQL packages and tarballs are now also available for ARM64 architectures. Thus, users can not only run Percona Distribution for PostgreSQL in Docker containers on ARM-based workstations but also install the packages on those workstations. The ARM64 packages are available for the following operating systems:
+
+    * Red Hat Enterprise Linux 8 and compatible derivatives
+    * Red Hat Enterprise Linux 9 and compatible derivatives
+    * Ubuntu 20.04 (Focal Fossa)
+    * Ubuntu 22.04 (Jammy Jellyfish)
+    * Ubuntu 24.04 (Noble Numbat)
+    * Debian 11
+    * Debian 12
+
+* Percona Distribution for PostgreSQL includes the enhanced telemetry feature and provides comprehensive information about how telemetry works, its components and metrics as well as updated methods how to disable telemetry. Read more in [Telemetry and data collection](telemetry.md)
+
+* Percona Distribution for PostgreSQL includes `pg_stat_monitor` 2.1.0 that provides the ability to [disable the application name tracking for a query](https://docs.percona.com/pg-stat-monitor/configuration.html#pg_stat_monitorpgsm_track_application_names). This way you can optimize query execution performance.  
+
