The past 3 months we’ve been working feverishly on the next version of WordPress, 2.3. Today we’re releasing the first beta of 2.3 and we’re hoping the more adventurous and savvy among you will help us test it.
Some of the features of 2.3 include plugin and core update notification, built-in tags support, faster javascript, and SEO-friendly URL redirection.
However all of the new functionality is still very rough, so only test the beta if you are comfortable troubleshooting PHP issues, filing tickets, and backing up your data religiously. If you’re interested you can join the wp-testers mailing list and download the beta here.
