How urgent would it be to upgrade a WordPress 2.7 to 3.0.1?
The reason I'm asking is because one of my clients has 2.7 and I did encorage him to upgrade to 3.0.1. He would like to wait a bit before to upgrade. I'd like to advise him how long he can keep the site in 2.7.
Whether if it's a year or it's a MUST update now.
If anyone can help that would be appreciated. Thanks.
