**Classic Profile Deprecation:** As new features are added in Xamarin.Mac we are starting to gradually deprecate features from the classic profile (xammac.dll). In this release the non-NRC (new-ref-count) option was removed. NRC has always been enabled for all unified applications (i.e. non-NRC was never an option) and has no known issues.
- The latest features and API requires Xcode 7.2 and the bundled macosx10.11 SDK;
- Apple Xcode 7.2 requires a Mac running OSX 10.10 (Yosemite) or 10.11 (El Capitan)
- NSAccessibility - NSAccessibility related protocols have been bound and existiting classes such as NSApplication and NSButton now expose them
- System.Runtime.Remoting has been added to the XM 4.5 target framework BCL
Preview released at Evolve 2016
