By being a little carefree here. And yes, I acknowledge that this is a
silly mistake entirely of my own making that shouldn't really have ever
been happened. Just that now it has.
I've always installed by checking out master, doing a git pull, checking
out the release tag I want (which puts Git to a "detached head" state),
and then ./configure && make && sudo make install.
Now, I've clearly forgotten to check out the right release tag before
running configure and then furthermore also forgotten to check what
version actually got compiled. It's not like configure or make is
actually shouting out loudly the version being compiled.
And because you can't do git pull in a detached head state, you'll have
to temporarily check out some branch for that anyway. But in retrospect,
it would've made far more sense to use one of the stable branches
instead of the master branch; this mistake would still have been
possible, but the resulting version wouldn't have been that far away
from a tag release, causing less trouble.

So you think that the DB should still be OK after downgrading to 4.3.0,
without any other action? OK, I'll give it a try (but I'll still use Git).
After reading the Git logs between
1fcad53d7ca1be619bbc9572100b38886114dee7 and not finding anything that
looked like a DB change I would have most likely done that anyway, but I
just wanted a secondary opinion. Thanks!
