This was realy an update from Qt4.5

it's compatible QDevelop with the new Qt? maybe realy need update D:

As for me QDevelop works with Qt 4.5. But! Qt 4.5 is VERY unstable and has a lot of serious troubles with rendering and performance. I wouldn't recommend anyone to use it until it stabilize. Is it what you wanted?

;D yeah thx! i only hope don't have much problems in development for works in my university!

As to our company we stay on Qt 4.4.3 until the situation changes.
