a problem, I just want to know if this is required.
ping for decision prior to 6.3 feature freeze.
With https://codereview.qt-project.org/c/qt/qtbase/+/378053 it's now
possible to turn off the package version check and to use moc of a
different Qt version. This requires that moc stays either compatible or
handles that /version argument outlined elsewhere in this thread.
Which is great, and is what I want, but we still need a decision on how long
the compatibility window will be and how we will inform the tools of what
version we're asking for.
A sliding window of two years has been proposed in this thread.
Assuming two minor version bumps per year, that's four minor versions.
Let's make that an odd number and we get the following
Proposal 1:
Qt 6.X should work with host tools of Qt 6.Y, where X-2 <= Y <= X+2
That's quite some commitment.
How about
Proposal 2:
Qt 6.X should work with host tools of Qt 6.Y, where X-1 <= Y <= X+1
That gives us less to test, and the sliding window is something like 1.5
years.
