+<!-- more -->
+
+[`pg_tde` :octicons-link-external-16:](https://docs.percona.com/pg-tde/index.html){:target="_blank"} is an open source extension for PostgreSQL that brings native data-at-rest encryption, now with production-ready WAL encryption.
+
+Try it out using the [installation guidelines :octicons-link-external-16:](https://docs.percona.com/pg-tde/install.html){:target="_blank"}.
+
+## Added support for PostgreSQL 18.1
+
+`pg_tde` is fully supported with the Postgres 18.1 version.
+
+## `pg_tde` packaging changes
+
+Starting with PostgreSQL 18, `pg_tde` is distributed as a **standalone package** and is no longer bundled with the server package.
+
+For more information on the availability by PostgreSQL version, please see the [Install pg_tde](https://docs.percona.com/pg-tde/install.html) topic.
+
+## Added support for AIO
+
+Added support for **asynchronous I/O (AIO)** which is now the default I/O mechanism.
+
+### Repository split for multi-version PostgreSQL support
+
+Reorganized the project into a multi-repository structure to support several PostgreSQL versions more efficiently.
