ColdFusion Builder 3 update 2 released last week had a bug because of which colorization used to break in cfscript code when it was edited around comments. This bug has been fixed in the update 3 that is released today. Update 3 does not contain any other bug fixes.
Note-1/23/2015 (Krishna) :
We had refreshed the update 2 just fixing the bugs arised out of Update 2. Ram has blogged it as Update 3 mistakenly. It should have been blogged as Refreshed build for Update 2. Our apologies for the confusion with regard to the update number.
