API Tools 3.5M2 New and Noteworthy

API compatibility options have been simplified: the number of options has been reduced, options have been re-grouped, and descriptions have been improved. For example, compatibility options related to type parameters are now in their own group rather being duplicated in the settings for classes, interfaces, methods, and so on.

A large regression test suite (with over 1600 tests) has been developed to validate API use, compatibility, and version management scenarios.
