https://github.com/munki/munki/releases/tag/v3.6.0
This is the official release of Munki 3.6, an important new release of the Munki tools.
The primary new feature of Munki 3.6 is new versions of Managed Software Center.app and MunkiStatus.app, rewritten in Swift. These new applications are intended to behave nearly the same as the PyObjC-based applications they replace, with some speed and reliability improvements.
Munki 3.6 will install (and is supported) on macOS 10.10+. Older macOS versions are no longer supported.
