If you're a developer of Qt (which you are), then the latest dev branch of 
every module or the latest 6.0 branch of every module works. If there are 
issues, you need to fix them and contribute.

If you're not a developer of Qt, then use a release.

Like I said above, the latest tip of the branch for every single module. This 
recipe has worked for me for 10 years.

For my direct work, only qtbase.

For running Qt Creator, well, almost all of them.

I didn't know that.
