Is it worth delaying the release?

Is it worth delaying the release until after the 3.9 upgrade and the VMMaker upgrade? I've just started moving to a 3.9 image. There are 24 failing tests, most are because 3.9 produces different bytecodes than 3.8 for some things. This seems to be due to block processing but I haven't fully investigated.

There are a few other failures including one due to a bug in 3.9.

Is it more useful for me to release as is. A solid release on 3.8 before moving to 3.9 or to upgrade everything now. I'm going to upgrade next anyway. I'm not going to maintain different tests for both releases so once I fix them for 3.9 they will fail in 3.8.
