+# pg_tde 2.0 ({{date.2.0}})
+
+The `pg_tde` by Percona extension brings in [Transparent Data Encryption (TDE)](../index/index.md) to PostgreSQL and enables you to keep sensitive data safe and secure.
+
+[Get Started](../install.md){.md-button}
+
+## Release Highlights
+
+* **WAL encryption is still in Beta**
+
+The WAL encryption feature is currently still in beta and is not effective unless explicitly enabled. **It is not yet production ready.** Do **not** enable this feature in production environments.
+
+## Known issues
+
+* The default `mlock` limit on Rocky Linux 8 for ARM64-based architectures equals the memory page size and is 64 Kb. This results in the child process with `pg_tde` failing to allocate another memory page because the max memory limit is reached by the parent process.
+
+To prevent this, you can change the `mlock` limit to be at least twice bigger than the memory page size:
+
+* temporarily for the current session using the `ulimit -l <value>` command.
+* set a new hard limit in the `/etc/security/limits.conf` file. To do so, you require the superuser privileges.
+
+Adjust the limits with caution since it affects other processes running in your system.
