The last months, in a rather large amount of effort, Håkon Vågsether has been able to port GNU Radio 3 from Qt5 to Qt6.
These are the kinds of changes a project *has* to do, whether it wants to or not, because if it doesn't, it will fall out of Linux distributions, it will become hard to install, and hence its core mission hurts. On the way, numerous bugs in the original code have been found, and worked around / fixed.
Thanks, Håkon!

And: This paves the way to a coming GNU Radio 3.11 release!
