Since I've upgraded to Version 3.0 It's been an awful experience writing new posts. I've also tried rolling back version 2.92, but when I sign back on it tells me I HAVE to upgrade. I'll be honest and say I hate it so far. So I'm stuck with it.
Tags- I can't add tags to posts. Come on guys really?!
Pics- The last version used to have a pop up window where you upload and add your pics as a thumbnail, not called featured post.. Now you go to a new page where it is all done with no link back to the article or dashboard or article what so ever.
Custom Fields- If you add a custom field the entire page refreshed, and if you haven't saved all of your work as a draft you will lose it.
WPEzinearticles- I also submit my blog articles for EzineArticles. The plugin no long works. Some aspects of it do. like being able to choose a category, but, you're not able to submit the article nor edit keywords or the summary.
CyStats My stats are now all out of whack. Makes it very difficult to accurately monitor traffic.
Upgrades are great, but not at the expense of users who use WordPress to make life easier. I think more time should've been given before it's release, and a roll back option should be given for those who wish to wait while all of the kinks are hashed out. I didn't sign up to be a tester or guinea pig at the expense of my blog.
That's all I have for now. But I'll definitely be back.
