By now I probably sound like a broken record, but for now I suggest that WishList Member users not upgrade to WordPress 3.1 right now.
I have not heard of any specific issues, but WishList is a mission critical application in your business and it is best to wait until the WishList team has had an opportunity to give it a thorough test.
I’ve been testing the beta versions on my development sites and will be spending the weekend testing the final release. But that’s not the real world. Also I will be on a call with other developers this afternoon to learn what they are experiencing.
If you want to follow the chatter at WordPress visit their Installation Forum.
Please leave a comment of send us an e-mail if you had any problems or positive experiences.
I’ll write another post and e-mail our list when the coast is clear.
Have a great weekend.
