> "now available in version 6 with much less restricted licenses"... that's quite a weak praise given that it is available as LGPL, GPL or commercial non FOSS licensing.

I was already writing UI applications with an LGPL licensed Qt 4.x, so the version 6 hasn't changed in that regard, just like version 5 didn't change either. And I'm sure Qt was already FOSS in earlier versions, but 4 and 5 are the ones I can confirm having FOSS licenses.




From memory version 2 is the one that moved to gpl and this happened before 2001.

So this is reheating a 20 year old talking point.


IIRC Qt now requires registration to download their releases. And some drama around how frequently OSS releases would get updates.

not if you use it throuh vcpkg or https://pypi.org/project/aqtinstall/ or your distro's package manager or mingw or...


Aren't these all downstream sources, and therefore may lag or fork?

IME it used to be possible to anonymously get binaries and sources from Qt themselves.


aqt uses the upstream qt repos


Qt3 was GPL (or commercial); with Qt4 LGPL option was added.
