[Mediawiki-l] Upgrading: what happens to extensions

It depends on the extension and what it does. Those which alter the
database, for instance, will need to be upgraded as the wiki is, to
ensure that the schema available is as expected; the prominent example
of this would be the transition from 1.4 to 1.5 or above, where the
schema has been altered to make it more efficient, meaning that data
is no longer in cur / old tables.
I would recommend checking the documentation (if it exists) for the
extensions being used, and see what minimum versions are required.
Upgrading within a branch, however, should not alter the base code to
the point where an extension won't work.
It's a point that those authoring extensions need to consider; how is
their code affected by MediaWiki's? I, for example, write and test
extensions against the 1.5 release code and the 1.6 alpha code; but
those aren't compatible with older versions. Conversely, I've seen
extensions which continue to be released past 1.5 release dates, which
still assume the old schema.
