+# pg_tde technical preview release notes (2024-03-28)
+
+`pg_tde` extension brings in [Transparent Data Encryption (TDE)](tde.md) to PostgreSQL and enables you to keep sensitive data safe and secure.
+
+[Get started](../install.md){.md-button}
+
+## Release Highlights
+
+The technical preview of the extension introduces the following key features:
+
+* You can now rotate master keys used for data encryption. This reduces the risk of long-term exposure to potential attacks and helps you comply with security standards such as GDPR, HIPAA, and PCI DSS.
+
+* You can now configure encryption differently for each database. For example, encrypt specific tables in some databases with different encryption keys while keeping others non-encrypted.
+
+* Keyring configuration has undergone several improvements, namely:
+
+    * You can define separate keyring configuration for each database
+    * You can change keyring configuration dynamically, without having to restart the server
+    * The keyring configuration is now stored in a catalog separately for each database, instead of a configuration file
+    * Avoid storing secrets in the unencrypted catalog by configuring keyring parameters to be read from external sources (file, http(s) request).
+
+## Improvements 
+
+* Renamed the repository and Docker image from `postgres-tde-ext` to `pg_tde`. The extension name remains unchanged.
+* Changed the Initialization Vector (IV) calculation of both the data and internal keys
+
+## Bugs fixed
+
+* Fixed toast related crashes
+* Fixed a crash with the DELETE statement 
+* Fixed performance-related issues
+* Fixed a bug where `pg_tde` sent many 404 requests to the Vault server
+* Fixed сompatibility issues with old OpenSSL versions
+* Fixed сompatibility with old Curl versions
