We're overdue for a stable release but there turned out to be a few more new changes to make. If this release goes smoothly we'll make r90 a stable update.
New this build: Export to CocoonJS! CocoonJS by Ludei provides a hardware-accelerated engine to accelerate HTML5 games to native-like performance, then publish them as Android apps. Hopefully this will solve performance issues on Android. We're also working to support directCanvas, a similar technology by appMobi for iOS as well. CocoonJS support in Construct 2 should be considered early beta, since both Ludei and us need to work on it further to get it working smoothly. However as always our policy is to release early and often. So if you want to try it out: install the 'CocoonJS Launcher' app, register, zip the exported files and upload the zip (e.g. to Dropbox), enter the URL to the zip in the launcher app, and try running. Please note this feature is not available in the free edition. There are lots more details to work out such as the publishing workflow, but for now you can try out the technology from Construct 2.
