WordPress 2.0 Beta 1 was quietly released early Saturday morning. So quietly that this is probably the first post about it anywhere.
Previously known as 1.6, lead developer Matt Mullenweg decided that the changes to WordPress were extensive enough to warrant a major version number change.
I’ve been running it at Make Stupidity History for some time, and while there are certainly still a few bugs to iron out, it’s probably almost ready for prime time.
It is certainly ready for plugin authors to start working with and updating their plugins. Many plugin authors will find that their plugins are broken in 2.0 and need to be updated, due to the extensive internal changes.
If you need help with it, post in the Beta forum.
