QtCreator build mode: Profile

Question

I've just upgraded to the latest QtCreator IDE and found out that among old two build modes {release, debug} there is a third one: Profile. Could someone point me to the explanation of difference between this new mode and the old ones?
I guess it should be related to Valgrind function profiler that usually takes Release builds only.

From Qt Documentation.

A profile configuration is an optimized release build that is delivered with separate debug information. It is best suited for analyzing applications.

On Windows. It will create pdb alone with release version exe. Run faster and can still debug with symbols using Just-In-Time Debugger
