Drupal 4.6 was released yesterday and anybody interested in "podcasting" will be happy to note that one of the new features that it provides is native support for RSS 2.0. In other words, the first file that is attached to nodes will be referenced in enclosures included in any/all relevant RSS feeds that are generated.

Another interesting development for the podcasting community is that there has also been a "CreativeCommons" module developed for Drupal recently. While this is still in the CVS tree, I have tried it out and it totally rocks.

Lastly, I'll mention that a new "media" module makes it easy to setup websites that allow users to build and then stream playlists based on uploaded content.

I can't help imagine some of the alternative broadcasting platforms that are made possible by these improvements alone, not to mention all of the other great community-building modules that already exist for Drupal.
