BroodWar's Battle.snp:

Never seen this, not on BNLS doc - is it still around?

It's another status code that isn't ever used in the wild (Diablo II refers to this as downgrade required).

I wonder what would make the server decide to send it... when would you ever need to reinstall as opposed to just applying another patch? Patches don't enforce an earlier version, the updater will quite happily apply an old patch to a current version, so hmmm...

IIRC, the game just puts up an error messagebox and disconnects.  Because the patching system can already handle reverting to older versions (automatically), it's even more unlikely that this would ever be used.

Hmm, I do remember one time where my brother downloaded a patch on D2, and was forced to reinstall the game

IIRC, there were two D2 v1.09d versions; if you got the first version, you would have needed to reinstall.  However, the server simply reported a failed version check.  The time window for getting the bad v1.09d was fairly small (<1hour I believe).

Hmm, D2XP's Bnclient.dll, 1.10:

.text:6FF02C0C loc_6FF02C0C:                           ; CODE XREF: Parse0x51+AFj
.text:6FF02C0C                 cmp     esi, 102h
.text:6FF02C12                 jnz     loc_6FF02D46
.text:6FF02C18                 mov     ecx, 1
.text:6FF02C1D                 call    sub_6FF06580
.text:6FF02C22                 mov     dword_6FF1D2C4, ebx
.text:6FF02C28                 push    offset aUserMustRevert ; "User must revert to an older version"

If there was a connection mechanism to connect the D2 1.10 beta to Battle.net (there wasn't one provided in the user interface, but one may have been able to try to hack it), I presume something like this would have surfaced, as well.
