In the Preferences panel, if you click the ‘Read in Browser’ button, to access Framework Setup Guide, the provided URL ( http://www.cocos.com/docs/creator/publish/setup-native-development.html ) is invalid.
That’s the only ‘bug’ I found so far, if we can call this a bug, but stay tuned, I will try to find more 
(I’m sure you already know, but just in case please note that slicing sprites issue with Firefox still occur with this version and is maybe worse than with 1.0-rc1, as some sprites that was rendering fine with 1.0-rc1, are not, now)
PS: I love the fact I can now have access to documentation and API in English, good job ‘guys’ !
