Aaron Brazell, co-author of the 10 things you should know about WordPress 2.0, has posted a similar article about the 2.1 release of WordPress.

Tomorrow, WordPress 2.1 will be released and it signifies the first major release since the 2.0 branch was launched. As is typical of major releases, they do not only address security/bugfixes but they release new functionality.

So in the spirit of the original article, I give you ten things you should know about WordPress 2.1.

It’s an extensive article, going into great detail about all the major changes & enhancements that are in the new release.  Looking forward to this release. The image uploads handling improvements will be worth the upgrade alone. I’ve found the popup menu on images has been the single most confusing part of the admin interface for users. Anything that will simplify this it a plus.
