As of my last update in September 2021, Ubuntu Server 22.04 LTS had not been released. However, it is likely that it would be the next long-term support (LTS) release of Ubuntu Server following Ubuntu 20.04 LTS, which was released in April 2020.

Ubuntu Server 22.04 LTS is expected to continue the Ubuntu tradition of providing a stable, secure, and reliable server operating system, suitable for various server applications, cloud deployments, and data centers.

Please note that specific details about Ubuntu Server 22.04 LTS, including its features and improvements, would be available closer to its actual release date. For the most up-to-date information, I recommend checking the official Ubuntu website or relevant community sources for announcements and release notes when Ubuntu Server 22.04 LTS becomes available.
