This build is a stable release update so everyone is recommended to upgrade to it. This is following the last stable release r80.2 by about a month, and I think weekly beta updates and approximately monthly stable updates is a good schedule to follow.
There are only minor tweaks in this build over the r83 beta. However, if you're upgrading from r80.2, you are encouraged to review the intervening beta release changelogs:
- r81 which introduced experimental support for building Windows 8 Metro apps and fixed audio on PhoneGap
- r82 which introduced a prototype translations engine
- r83 which introduced a new icon set throughout the editor
See the release links for the full changelogs. There was one breaking change in r83 involving the 'Is visible' condition.
Note this is the first unchecked build. This means you will not see any 'check failure' dialogs - they've been compiled out. The checks will be included in all future beta releases, though.
