I rebased Deere's wine builds onto 7.0.1-rc1 and the it looks good to me! Only thing missing was that `wine --version` still called itself 7.0, not 7.0.1-rc1, because PACKAGE_VERSION in configure wasn't changed. But that seems consistent with how older tags (like 6.0.1-rc1) were made; only the actually-final tags changed configure. So I assume that's intentional.
I did hit a very weird double-free crash on aarch64 (somehow involving CoUnintialize, but I didn't get a very usable backtrace). But after some digging it seems to be a rare threading race in our app code, not wine's fault. I was eventually able to provoke the same crash running on 7.0 as well, so it hasn't got anything to do with 7.0.1-rc1, we just have a bug in our app and it picked the run where I was testing 7.0.1 to finally show itself...
