+# Features
+
+We provide `pg_tde` in two versions for both PostgreSQL Community and [Percona Server for PostgreSQL](https://docs.percona.com/postgresql/17/). The difference between the versions is in the set of included features which in its turn depends on the Storage Manager API. While PostgreSQL Community uses the default Storage Manager API, Percona Server for PostgreSQL extends the Storage Manager API enabling to integrate custom storage managers.
+
+The following table provides features available for each version:

 ## What's encrypted:
 
-`pg_tde` encrypts the following:
-
 * User data in tables, including TOAST tables, that are created using the extension. Metadata of those tables is not encrypted. 
 * Temporary tables created during the database operation for data tables created using the extension
 * Write-Ahead Log (WAL) data for the entire database cluster. This includes WAL data in encrypted and non-encrypted tables
 * Indexes on encrypted tables 
 * Logical replication on encrypted tables

+## Beta 2 (2024-12-16)
+
+With this release, `pg_tde` extension offers two database specific versions:
+
+*  PostgreSQL Community version provides only the `tde_heap_basic` access method using which you can introduce table encryption and WAL encryption for data in the encrypted tables. Index data remains unencrypted.
+* Version for Percona Server for PostgreSQL provides the `tde_heap`access method. using this method you can encrypt index data in encrypted tables thus increasing the safety of your sensitive data. For backward compatibility, the `tde_heap_basic` method is available in this version too. 
+
+The Beta 2 version introduces the following features and improvements:
+
+### New Features
+
+* Added the `tde_heap` access method with which you can now enable index encryption for encrypted tables and global WAL data encryption. To use this access method, you must install Percona Server for PostgreSQL. Check the [installation guide](../install.md)
+* Added event triggers to identify index creation operations on encrypted tables and store those in a custom storage. 
+* Added support for secure transfer of keys using the [OASIS Key Management Interoperability Protocol (KMIP)](https://docs.oasis-open.org/kmip/kmip-spec/v2.0/os/kmip-spec-v2.0-os.html). The KMIP implementation was tested with the PyKMIP server and the HashiCorp Vault Enterprise KMIP Secrets Engine. 
+
+
+### Improvements
+
+* WAL encryption improvements:
+
+   * Added a global key to encrypt WAL data in global space
+   * Added WAL key management
+
+* Keyring improvements:
+
+    * Renamed functions to point their usage for principal key management
+    * Improved keyring provider management across databases and the global space.
+    * Keyring configuration now uses common JSON API. This simplifies code handling and enables frontend tools like `pg_waldump` to read the code thus improving debugging.
+
+* The `pg_tde_is_encrypted` function now supports custom schemas in the format of `pg_tde_is_encrypted('schema.table');`
+* Changed the location of internal TDE files: instead of the database directory, now all files are stored in ` $PGDATA/pg_tde`
+* Improved error reporting when `pg_tde` is not added to the `shared_preload_libraries`
+* Improved memory usage of `tde_heap_basic `during sequential reads
+* Improved `tde_heap_basic` for select statements
+* Added encryption support for (some) command line utilities
+
+### Bugs fixed
+
+* Fixed multiple bugs with `tde_heap_basic` and TOAST records
+* Fixed various memory leaks
+
 ## Beta (2024-06-30)
 
 With this version, the access method for `pg_tde` extension is renamed `tde_heap_basic`. Use this access method name to create tables. Find guidelines in [Test TDE](../test.md) tutorial.
