Provisioning: New nodes automatically synchronize when added to the cluster.

Encryption: The pxc-encrypt-cluster-traffic variable enables automatic SSL encryption configuration for cluster traffic.
Compatibility: PXC 8.4 is fully compatible with MySQL Server Community Edition 8.4 and Percona Server for MySQL 8.4.
Application changes: Applications using the cluster require no changes or minimal changes, according to the product documentation.
