In case anyone else has recently frozen up to the latest rails edge and gets this ‘config.breakpoint_server’ notice:
I actually found the solution to this at http://dev.rubyonrails.org/browser/trun … v=7183#L56 if anyone else is interested. Just remove the ‘config.breakpoint_server = true’ on line 12 of environments\development.rb and the deprecated error is no longer displayed when you migrate, run WEBrick, etc.
