This build mainly fixes up some bugs in Physics and adds some missing features that were requested. However, there's a new 'pixel rounding' option that retro style games might find useful.
I've fixed an issue with the way sprite animations are saved to disk in this release. Hopefully it will also fix a rare issue with projects becoming unopenable. However, if I made a mistake, it could cause unopenable projects! So please back up your existing projects before opening them with r59. Construct 2 is beta software so you ought to be making regular backups anyway, but this one has changes in important saving code, and mistakes there can be serious.
That aside, don't forget to check the Examples directory if you haven't already! Click 'Browse all examples' on the welcome screen to see them. They cover a lot of useful features and common techniques!
Also, we're on holiday next week! Scirra will be away from 1st to 8th October. We'll try and get back on top of things as soon as possible when we get back, but we won't be answering emails, making forum posts or doing bug fixes/new releases during that time. Hopefully nothing will go horribly wrong while we're away! :) Things will be back to normal after 8th October.
