I missed this discussion previously, so sorry for bumping, but I thought
it was worth noting Firefox's process for this:


As far as I know, that's all done automatically. It'd be awesome to try
and do this for WordPress as well. The easiest way I can think of doing
it is to search for any APIs we've changed in the plugin files. If we
detect that a plugin uses those APIs, we can either mark it as
incompatible straight away, or do some better API compatibility
checking. The latter would be preferable, but I'm not sure how easy it
would be (most likely, we're going to have to run the plugin, or do
complicated stuff with the tokenizer, and neither of those sound
appealing to me).

Automatic updates are something I'm planning to try in my own software,
so I'll see how that goes.
