Recommended : Update all of your out-dated system drivers in just 2 minutes
In less than a week after migrating to this self-hosted WordPress blog from my old Blogger blog ( with still a bunch of tweaking to do ) , now here come the new WordPress version 2.5. Probably a good news for all WordPress users out there but at least not for me because now I have to get my head around again. 
I have downloaded a copy of WordPress 2.5 ( If you haven’t , go here to download ) but at the time of writing, this blog is still using WordPress 2.3.3. I will upgrade to WordPress 2.5 shortly after. Good luck to me (and you)!
By the way, before upgrading , you may want to deactivate/delete any of these plugins ( if you have them ) because they are no longer needed in WordPress 2.5. Here are they.
- Full Text Feed
- OneClick plug-in
- Gravatars/Avatars related plugins ( cos WordPress 2.5 comes with Gravatars support )
- Any more?
You also may want to check out these non-working plugins, or have issues with WordPress 2.5 here.
Okay, I want upgrade to WordPress 2.5 now. Have a nice day! 
Updated : My Tech Quest has been successfully upgraded to WordPress 2.5.
Congrats! You are fast! I haven’t update my WordPress, probably will do it today. Before that, I would like to try out some new features in 2.5 in my localhost first. Oh, by the way, the Popularity Contest plugin is not compatible with WP 2.5.
I searched other blog too.. some of them seaid NextGEN gallery also doesn’t work on the lateset version of wordpress
