Apple has released macOS Server 5.2 (previously called OS X Server), which adds support for macOS 10.12 Sierra, as one might expect, and for migrating Server data from a volume with El Capitan 10.11.6 and OS X Server 5.1.7 or Yosemite 10.10.5 and OS X Server 5.0.15. The release adds integration with Apple School Manager, enables you to skip the Siri Setup Assistant pane in Sierra, provides enhanced control over peer replication, improves security by requiring SMB connections to be signed by default, and adds support for the Xsan 5 file system. macOS Server 5.2 now requires a minimum of OS X 10.11.6. ($19.99 new, free update, 199 MB, release notes, 10.11.6+)
