Please update now.
What am I speaking of?? The version update feature that is packaged in the new 2.3.+ version of WordPress. I heard about it in the buzz about the new version in the weeks prior to it being released. Now that WordPress 2.3.1 is out - I’m seeing it in my WordPress Dashboard and it looks like this:

This nifty feature tells you when your WordPress software is out of date and a new version has been released. This is really nice, especially for those who don’t keep updated on such information on a regular basis.
Now, there are some folks who are concerned about the privacy issues surrounding this particular feature. In order for this feature to work - there is a bit of code in the core WordPress files that need to ‘call home’ to the WordPress servers. It makes sense - in order for your WordPress Dashboard to notify you that you’re out of date with your version - there needs to be a call to a central server at WordPress.org - - it sends information like your version, your domain and your blog name - and returns the message back that you’re out of date.
Likewise, there is another update notification system in place for your WordPress plugins. It’s a nice feature you’ll see under the Plugins tab that will tell you if you are using an old version of a particular plugin - - it’s really nice to know if there is a new version of your favorite plugin, isn’t it? That notifcation looks something like this:

Same type of call home - - same privacy concerns, for some.
Due to privacy concerns surrounding this (some people just aren’t comfortable with that call back to WordPress.org) - there have been some plugins developed to disable this feature. Just know - if you use any of these plugins, you will need to keep yourself informed about WordPress update releases as they come out! Here’s a few plugins to disable the software and plugin update notification feature in WordPress:

Anonymous WordPress Plugin Updates by Hannes Hofmann (this plugin allows the updates but anonymizes the plugin update checking system)
