Enjoy the new version. I haven't been able to test it on Live yet, but everything should be fixed for 4.2; in theory.

Don't install this update before 4.2 is live in your region! It won't work properly on 4.1.

One remark: If DOTS keep turning red and falling off with this version on 4.2, switch off 'Advanced Options > Spell Timer > Improve : Use dot ticks'. I noticed on the PTR that damage ticks were not always properly showing up in the combat log, but this may be fine on Live servers.
