The WordPress development team has just announced the immediate availability of WordPress version 2.9. You can upgrade easily from within your Dashboard by going to Tools > Upgrade, or you can download from WordPress.org directly.

This version is a major release and so they have prepared a short video summarizing some of the cool things about the new WordPress 2.9.

Here is a list of some of the major additions from a user point of view.

• Global undo/”trash” feature, which means that if you accidentally delete a post or comment you can bring it back from the grave (i.e., the Trash). This also eliminates those annoying “are you sure” messages we used to have on every delete.
• Built-in image editor allows you to crop, edit, rotate, flip, and scale your images to show them who’s boss. This is the first wave of our many planned media-handling improvements.
• Batch plugin update and compatibility checking, which means you can update 10 plugins at once, versus having to do multiple clicks for each one.
• Easier video embeds that allow you to just paste a URL on its own line and have it magically turn it into the proper embed code, with Oembed support for YouTube, Daily Motion, Blip.tv, Flickr, Hulu, Viddler, Qik, Revision3, Scribd, Google Video, Photobucket, PollDaddy, and WordPress.tv (and more in the next release).

Remember you can  download the new WordPress 2.9  from the WordPress.org website.

Have fun
