Well, I know we now have 2.1.43 ;D so this is less important.
BUT … I just double-checked the version in Snapshot and did an fc command against my previously-downloaded copy of build 483: no differences encountered (!). So, I think that the version in Snapshot really is build 483, though as I said, that doesn’t really matter now!
I’ve also just downloaded 2.1.43 and I’m about to go and try it.
