Spidermonkey changes since 1.8.5

Miles Thornton
Several months ago I upgraded our embedding of Spidermonkey to 1.8.5 (which I believe is the latest standalone source code release version roughly corresponding to the engine in Firefox 4).
It seems that Firefox is being developed at quite a pace. I'm currently running version 9...
Does anybody know if there are any significant changes in Spidermonkey between version 1.8.5 and the current version?
i.e. are there any compelling reasons to get a newer version such as increased performance or reduced memory footprint etc?
If there are any differences then are they documented anywhere?

Also, I'm not quite sure if this is the place to ask or not, but we embed Spidermonkey into our own software to give a scripting capability. It is very popular and so we are now fairly committed to maintaining this! I've officially been given permission from my employers to use a *small* portion of my time to get involved with/help with Spidermonkey development. I'm not sure what skills I can offer but I'm sure that there is something I could help with. I'm based in the UK. Can anyone point me in the right direction?

Thanks

There are.  Type Inference is a big one.

Memory use has gone down, too, although not enough for typical embeddings
to notice.

Not explicitly, but there is information and developer.mozilla.org in the
docs, different features are tagged with different version numbers.

I am in the same boat.  It's a great way to get involved with the Mozilla
project.

bugzilla.mozilla.org  (yes, it's a firehose)
developer.mozilla.org
The place you *really* want to be is irc.mozilla.org, channel #jsapi,
especially during GMT-0800 business hours.
