Just tried to cut the 3.4.3 RC0 so I could say we did it in 2025, but it's failed, at least on the arm side YARN-11712: Yarn-ui build fails in ARM docker looking for python2.
x86 build is off on a vm somewhere in us-west-2 so I"ll see what it does, though by tomorrow all the date values will be obsolete. I'll revisit the system in an hour or so to see if it has built the x86 binaries and maven artifacts, and if so I'll announce it as a "preview" RC. We need that arm build now.
