Faq-O-Matic Faq-O-Matic : Administrators' Guide : Upgrade : Version History : Changes in 2.635 from 2.634
	In my eagerness to untaint $PATH, I made it empty, which prevents the not-fully-pathed 'cp' command in Log.pm from working. $PATH is now set to '/bin' to untaint it. This might be a hack; the right way is probably to explicitly specify *all* paths to external commands using the installer. (The only consequence of this is that the unique hosts statistics count may not have been correctly updated.)
	Michael Gerdts (gerdtsATcaeDOTwiscDOTedu) sent a patch to fix a very uncommonly occuring uninitialized value error in maintenance.pm. Thanks, Michael!
	Boyd Lynn Gerber (gerberbATzenezDOTcom) reported a "Substitution loop" error occurs in his Perl when I do $text =~ s/^/> /mg to quote some text. So I have replaced that replacement regex with an alternate implementation.
	jon * (jonATclearinkDOTcom) reported an uninitialized value bug in Appearance.pm that temporarily prevented him from upgrading from 2.622 to 2.634; it has been corrected in 2.635.
