It is a major release containing the following new features and improvements:

• Rocky Linux 8 and Alma Linux 8 support have been added
• CentOS Linux 8 support is removed
• Support for the libfabric/tcp provider is added. It replaces libfabric/sockets
• UCX support has been added (Technology Preview)
• Interoperability of DAOS 2.2 with DAOS 2.0
• Intel VMD devices are now supported in the control plane
• POSIX containers (DFS) now support file modification time (mtime)
