We will be updating WordPress when the new release comes out but this may create some bugs in third-party plugins installed. Note that if this happens there may be a charge in addressing the third-party issues.

"Release candidate 2 of WordPress 3.8 is now available for download. This is the last pre-release, and we expect it to be effectively identical to what’s officially released to the public on Thursday.
This means if you are a plugin or theme developer, start your engines! (If they’re not going already.) Lots of admin code has changed so it’s especially important to see if your plugin works well within the new admin design and layout, and update the “Tested up to:” part of your plugin readme.txt.
If there is something in your plugin that you’re unable to fix, or if you think you’ve found a bug, join us in #wordpress-dev in IRC, especially if you’re able to join during the dev chat on Wednesday, or post in the alpha/beta forum. The developers and designers who worked on this release are happy to help anyone update their code before the 3.8 release."
