New examples; Compatibility updates; Bug fixes.
1. The new minifier should work the same as the old one, and that includes full support for savegames.
2. The new minifier doesn't achieve quite as small sizes as the old one, which is a known difference, but it has much better support for modern JavaScript so we have to switch to it anyway to be able to keep making further improvements to Construct. It should still be highly effective at protecting projects against reverse-engineering as it still makes the code very difficult to read.
Thanks for answering!
