+
+## Release Highlights
+
+This release continues to deliver Percona’s open source value-add components for enterprise use cases, see the full component list below for details.
+
+!!! note
+    To upgrade from earlier versions (e.g. Percona Distribution for PostgreSQL 15.x), follow the steps in [Upgrading Percona Distribution for PostgreSQL](../major-upgrade.md).
+
+### Ubuntu 26.04 LTS support added
+
+ Percona Distribution for PostgreSQL is available on Ubuntu 26.04 LTS (Noble Numbat's successor). Packages are provided for AMD64 and ARM64 architectures.
+
+### Added Quick Start guide
+
+Added a Quick Start Guide walking users through setting up Percona Distribution for PostgreSQL with minimal steps and linking to more advanced topics.
+
+### Tarball updates
+
+The binary tarballs for x86_64 and ARM64 architectures have been updated in this release. The following libraries and components have new versions:
+
+- postgres-common: 290
+- pgBouncer: 1.25.2
+- etcd: 3.5.30
+- pysyncobj: 0.3.15
+- haproxy: 2.8.23
+- patroni: 4.1.3
+- pgpool2: 4.7.1
+- postgis: 3.5.6
+- pg_gather: 33

+
+See [Install Percona Distribution for PostgreSQL from binary tarballs](../tarball.md) for the download links.
+
+### Addressed CVEs
+
+This release includes important security measures that address the following CVEs: CVE-2026-6479, CVE-2026-6473, CVE-2026-6474, CVE-2026-6472, CVE-2026-6478, CVE-2026-6477, CVE-2026-6475, CVE-2026-6637. For more details, see the PostgreSQL [16.14 release notes](https://www.postgresql.org/docs/16/release-16-14.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.
