You should see in the wp updater that there is a newer version available and should be able to use that.
The core, plugins and themes will all update individually. The normal download packages from our site are arranged the same way.

The sitemaps plugin is broken? No – I didn’t know. Where did you discover this please?

Ok, I’ll try the WP updater.

On sitemaps, see this WP thread.  You will see numerous reports on the WP forum.  I reported it to Ipstenu the other night on Twitter.  My specific report was that beta 7 of the plugin is broken under multisite.  I also tested all of the other betas under multisite and they are broken too.  The “development” version is actually older than the betas; it’s just the current stable release.  That current stable release can’t be activated on multisite so I haven’t gotten around to testing it.

The error isn’t obvious.  You have to look at your sitemap.xml, and you’ll see the error at the top of the URL.  If you check in Google Webmaster Tools, you’ll see that the sitemap wasn’t read.  If you look at the debug link on the sitemap plugin, you’ll see (at least in beta 7) in 1 place that it was expecting a string but got an array.  I can’t say this broke it, because I never had reason to look at the debug data before now. 

I also didn’t check the current stable release on a stand-alone WP 3.3 installation.  The repository says it works, but I’m not sure if that is accurate in light of the fact that the error isn’t obvious.

If you have a fix, many will consider you a hero.

it “seems” to be working for standard wp installs…  but thats only a cursory glance – dont notice any errors in sitemap and no issues at google webmasters for multiple site…

I checked, and for single site installs with version 3.2.6 (the latest stable release), it does seem to work.

But none of the betas work on multisite.  The stable release will activate on multisite, but it says it does nothing.  The betas produce different errors.  Beta 7 does this:

Warning: Invalid argument supplied for foreach() in ../wp-includes/query.php on line 2746

That’s when attempting to view the sitemap.xml. Did you have different results on multisite? Using which beta?

when I said multiple site (sic), I mean on multiple different sites running sp and google xml sitemaps…  not wp multisite…  I dont have any live or test sites running the two together…

Updating from within WP 3.3 didn’t work.  It said my installation was up to date, even though it is clearly not, since it is just the alpha version.  Off to grab the download.

odd. the update has been tweaked/improved a bit during later part of alpha and in beta… but has been working for alpha (and beta) folks unless you were a bit out of date…
