New this build: support for exporting to Blackberry 10! Like Windows 8 and Firefox OS, Blackberry 10 allows for making native apps directly with HTML5, supported with a high-performance browser with broad HTML5 feature support, including WebGL!
Support for BB10 is experimental at this stage. Additional documentation should be forthcoming, and we may go in to more details on our blog in the near future. However if you have a BB10 device, you should be able to get an app on to your device once you've installed Web Works and requested signing keys. If it works you can submit to the App World (there's also a tutorial video covering the submission process). Since BB10 is a relatively new platform there's a good opportunity to get in before the competition increases. Blackberry may also be providing an additional BB10 plugin to access platform-specific features in future as well.
We also now support packaged apps (useful for Firefox OS), and we've updated to node-webkit 0.5 and jQuery 2.0. There's also the usual bunch of tweaks and fixes. Happy testing and be sure to let us know of any issues!
