Possibly a stupid question, but... latest stable version (right now) is 1.34 according to the sidebar. The answer to the frequently asked question "How do I upgrade from a really old version? In one step, or in several steps?" is "It depends: If you are upgrading from MediaWiki 1.4 or older, you should upgrade to MediaWiki 1.5 first." These are the current alpha and beta versions of mediawiki, right? Would it be better to give instructions that make sense for the current stable release? Is it ok to upgrade from 1.30.2 to 1.34, for instance.

No. MediaWiki 1.4.0 came out on 2005-03-20. It is very much not the alpha branch of MediaWiki, which is MediaWiki 1.35.
Thanks for the quick reply! Your answer is smart and my question was dumb, as I suspected it would be.
There are no dumb questions, worry not. :-)
