(I sent once, but never saw it appear, so resending... apologies if you see
Qt-5.6.1 updates have been submitted to -testing:
and is in kde-testing repos (was in kde-unstable previously).
FYI, blockers/regressions being tracked here,
One known issue is a crash regression with using kmix,
Hopefully that can be fixed soon, or we can finally use this to move
everyone to plasma-pa, now that plasma-pa-5.7.x releases has reached feature
parity. We could even consider releasing plasma-pa-5.7.x update prior to
the rest of plasma-5.7.x (it has no hard plasma-5.7-specific dependencies
that I'm aware of).
