I do not suggest updating until 2.7.1
Why is because when wordpress comes out with a major update, there are always issues. Those issues are most of the time worked out in the next small update.
Here is a video of the new wordpress 2.7
Oh how I’d love to play with this but I’d better hold off 
I figured it out Craig. Went into Cpanel and deleted the plug in file that caused the error message. I was trying to install feedburner-feedsmith when it happened. Now the error messages are gone after I’ve deleted the plug in off the server. Is Feedburner-Feedsmith a good plug in if you want to redirect your feeds to feedburner? Thanks for your help anyway. Many blessings
