Apple recently released a new version of the upcoming OS X 3.1 Server update with changes limited to general bug fixes and performance improvements. According to people who have tested the latest OS X 3.1 Preview build 13S4122, the beta is similar to the last release, which brought bug fixes and Profile Manager.

As for Profile Manager, the latest build brings a new “My Devices” portal access restriction and device enrollment restriction available on Users and Groups, as well as a feature that automatically retrieves an Activation Lock Bypass Code on enrollment of supervised devices.

The updates additional settings looks to be aimed at integration with Apple’s new mass iOS device deployment management program, which the company revealed in an update to its website at the end of February. Issues that were known include where Profile Manager would stop working after an upgrade or migration from OS X Server 2.x. According to Apple, the problem doesn’t affect upgrades or migration from OS X Server or 3.0 or later.

Developers who are interested can download OS X Server 3.1 Preview build 13S4122 via Software Update or Apple’s developer webpage. To test the software, developers must be running OS X Mavericks 10.9.2, which was released last week.
