-This release of Percona Distribution for PostgreSQL is based on Percona Server for PostgreSQL 18.1.1 - a binary compatible, open source drop in replacement of [PostgreSQL Community 18.1](https://www.postgresql.org/docs/18/release-18.html).
+This release of Percona Distribution for PostgreSQL is based on Percona Server for PostgreSQL 18.1.1 - a binary compatible, open source drop in replacement of [PostgreSQL Community 18.1](https://www.postgresql.org/docs/18/release-18-1.html).
+
+It introduces several major enhancements, such as: 
+
+- **Parallel logical replication** for improved throughput during initial data synchronization
+- **Faster in-place upgrades** via `pg_upgrade` performance improvements
+- **Enhanced monitoring** with new statistics views for `pg_stat_io` and background writer activity
+- **Security improvements**, including expanded SSL/TLS configuration options
+- **Performance optimizations** for query execution and index management 
+- Added support for **asynchronous I/O (AIO)** with PostgreSQL 18.1.1 which is now the default I/O mechanism.
+
+These features make PostgreSQL 18 a major step forward in scalability, observability, and operational efficiency.
 
 ## Release Highlights
 
-### SBOMs available for download
+This release continues to deliver Percona’s open source value-add components for enterprise use cases, including `pg_stat_monitor` 2.3.1 for advanced query-level observability, `pg_tde` 2.1 for Transparent Data Encryption and more. See the full component list below for details.
+
+!!! note
+  To upgrade from earlier versions (e.g. Percona Distribution for PostgreSQL 17.x), follow the steps in [Upgrading Percona Distribution for PostgreSQL](../major-upgrade.md).
+
+### `pg_tde` is now a standalone package
 
-Percona now provides Software Bill of Materials (SBOMs) to support compliance and security audits. SBOM files are available for tarball builds.
+Starting with PostgreSQL 18, `pg_tde` is no longer shipped with the server package. If your cluster relies on `pg_tde`, you must install the package manually.
 
-See [Software Bill of Materials (SBOMs)](../sboms.md) for the full list.
+For more information on installing `pg_tde`, see [Install pg_tde :octicons-link-external-16:](https://docs.percona.com/pg-tde/install.html).
