I’m sure many Flash/Flex developers noticed that now, with Flex Builder 3 Beta 2 we got only one SWF file after compilation. Previous versions made two or even three files (name_debug.swf, name_profile.swf).

This mess with files was annoying, because testing non-debug version you could only get only error code. Or, running debug-version not in a debug mode every time caused a new window with debugger port connect request (did you ever use that?).

It is is really important when you have dozens of swf-libraries, loading when neсessary.

In a second beta you don’t have to worry about all that anymore — we got only one SWF, which smoothly run in usual player (showing error class and string number), and it runs on debug player too. In my honour opinion, this is the best of all improvements. It is strange, I don’t see any celebrations on blogs and forums :) Have you noticed the improvement?
