Apple seeds new OS X Server 4.0 preview for testing ahead of OS X Yosemite launch

Apple on Wednesday released to developers a new version of OS X Server 4.0 carrying improvements to previously announced features, including SMB3 file sharing and new management options for devices running iOS 8 and OS X Yosemite.

According to the seed notes, Apple's latest OS X Server 4.0 build 14S323 brings a number of improvements to built-in systems like the server app, File Sharing and Profile Manager, all of which are designed to work with the upcoming OS X 10.10 Yosemite release.

Of note to enterprise users are Profile Manager features specific to Apple's recently released iOS 8 mobile operating system. With OS X Server 4.0, administrators have access to new payload settings and Mobile Device Management rules pertaining to cross-platform Continuity features introduced with iOS 8 and the forthcoming Yosemite. Along with tools offered in Apple Configurator 1.7, the new features offer more granular control over issued devices running the latest Apple software.

Apple requests developers to test upgrade and migration from OS X Snow Leopard and higher, as well as Xsan functionality.

Today's update comes one day after Apple issued the second OS X 10.10 Yosemite golden master build to developers, suggesting that the next-generation Mac OS will soon see public release.

Developers can download the latest OS X Server 4.0 release via Apple's Mac Dev Center.
