I see that on my Gentoo systems (x86), Qt 5.9.4 has gone stable. I just wanted to verify as to whether that's OK for MythTV 29.1, or whether there are any known issues etc. One other question...and I should probably know this but I can recall...does an upgrade from Qt 5.7.1 to Qt 5.9.4 require a recompile of MythTV? Thanks! Tom
