New this build: a new XML plugin (currently read-only), folder-organised condition/action dialog in the event sheet, JSON support for Arrays, and bug fixes for the new event features in r86. Note that the way OR blocks work has been changed to something more sane, which means existing documentation on how OR blocks work will change too.
This build should also fix Audio not working on PhoneGap. From time to time PhoneGap make breaking changes, and they don't really highlight them in their release notes, which is what caused the Audio problem - so please keep an eye out for anything else going funny with PhoneGap in future. (Also note PhoneGap recently renamed themselves to Cordova.)
