# Percona Distribution for PostgreSQL 17.5.3 ({{date.17_5_3}})

--8<-- "release-notes-intro.md"

This release of Percona Distribution for PostgreSQL is based on Percona Server for PostgreSQL 17.5.3 - a binary compatible, open source drop in replacement of [PostgreSQL Community 17.5](https://www.postgresql.org/docs/17/release-17-5.html).

## Release Highlights

### `pg_tde` 2.0 - WAL encryption now generally available

Percona Distribution for PostgreSQL includes the 2.0 release of `pg_tde`.
This version introduces several enhancements, most notably the general availability of WAL encryption.
See the [`pg_tde` release notes :octicons-link-external-16:](https://docs.percona.com/pg-tde/release-notes/release-notes-v2.0.html) for more details.

### Major documentation update in Percona Distribution for PostgreSQL

* Expanded and improved the [High Availability](../solutions/high-availability.md) topic with more information and example deployments.
* Updated the [PostGIS installation commands via yum](../yum.md#for-postgis) topic.
* Updated the [Telemetry](../telemetry.md) topic with revised steps and commands.
* Added new [FAQ](../faq.md) and [Versioning](../versioning.md) topics.
