Hi Dean, Thanks for doing the heavy lifting in getting kivy/2.1.0-1 ready for upload! I'm currently going through all of the packages that I (co-)maintain in preparation for the upcoming freeze, and you've saved me a ton of work here! I've pushed a few very minor changes to the packaging, but otherwise I think this is ready for upload; if Jeroen isn't planning on uploading kivy in the next day or so, I'd be happy to do so myself. I also invite you to add yourself as an Uploader in d/control if you anticipate maintaining kivy in the future.
One thing I wanted to bring up before actually uploading kivy is that you've added a new (emacs-specific) binary package, and adding a new binary package will force kivy to take a round-trip through the NEW queue. While that's not usually a problem, since we're so close to the freeze, there's a risk that ftpmasters may not be able to review it in time before the freeze takes effect. Would you consider either merging the contents of elpa-kivy-mode into python3-kivy, or defer adding the new package for a subsequent upload? Thanks! Regards, Vincent
