This build fixes some more bugs (notably with PhoneGap, OR blocks and Else) and has a few usability tweaks to make life a little easier in some places.
If you were wondering why it's been a long time (2 whole weeks between releases!!111), I went to a conference and also had some time off to relax. We've been working pretty hard for a long time! However we're back to work now and will still be aiming for weekly beta and monthly stable updates. If this release proves solid I would be looking to make the next release a stable update, since it's a little over a month since r84. Happy testing!
