OS X Server 5.1

Apple has released OS X Server 5.1, which has been updated for compatibility with OS X 10.11.4 El Capitan (see “OS X 10.11.4 Improves Notes, iBooks, and Live Photo Support,” 21 March 2016). In fact, OS X Server 5.1 now requires 10.11.4 El Capitan, and previous versions of OS X Server won’t work on 10.11.4 El Capitan, so you’ll need to make sure to install both updates. The release also adds support for TLS (Transport Layer Security) 1.2, adds support for the new education features in iOS 9.3 (see “iOS 9.3 Works the Night Shift, Protects Notes, and
,” 21 March 2016), adds new restrictions to the Profile Manager, and offers performance optimizations for iCloud data caching. According to this Apple security note, the update also addresses an issue in Time Machine Server that neglected to warn administrators if permissions were ignored when performing a server backup and patches a file access issue that existed in Apache with .DS_Store and .htaccess files. ($19.99 new, free update, 186 MB, release notes, 10.11.4+)
