[wp-docs] Upgrade info for sysops

[Michael E. Hancock]

Warning posted by Brion Vibber 9/27/2005 to upgrade MediWiki sites:
>>>>>>
In case some of you out there haven't got around to it, don't forget
that 1.4.10 (1.3.16 for 1.3 branch) fixes a serious data corruption bug
which is triggered by the requests a particular spambot uses.

I strongly urge anybody out there running a 1.3 or 1.4 MediaWiki to
upgrade or at least apply the fix patch described in the release
announcement:

http://mail.wikipedia.org/pipermail/mediawiki-announce/2005-September/000030.html

If your wiki gets hit by this corruption bug, you can only recover the
damaged data from a backup or extracting the original data from MySQL
binlogs, and that's a big pain in the butt.

1.5 wikis are not vulnerable to this problem.
