After the disaster of the Lightroom 6.2.x/CC 2015.2.x update, Adobe today released LR 6.3/2015.3. According to the release notes they've restored the old import dialog and fixed a number of other issues. For details see: http://blogs.adobe.com/lightroomjournal/2015/11/lightroom-cc-2015-3-6-3-now-available.html
For the moment I will wait with installing this update. Installing the previous update resulted in a lot of frustrations and finally rolling back to the previous version (CC 2015.1.x). I want to be sure if this update is stable enough.
