On February 16th Adobe has released an unplanned update of crobat DC to version 15.010.20059. There is only an update for subscribers of the Document Cloud (continuous track). Users with a perpetual license (classic track) get nothing.
One could think that the subscribers get new features and the users with a perpetual license not. But in the release notes of the new version only two bug fixes (PDF Library and Webcapture) are mentioned.
