Apple is launching a tweaked version of iTunes today (version 7.2)… it doesn’t appear to contain any upgrades or changes to the podcasting platform, but since it is by far the most used podcatcher out there, it’s good to know there’s some changes coming down the pike! Apple says the main feature in iTunes 7.2 is the ability to buy the new DRM-free tracks from the iTunes Music Store… that’s worth the upgrade for a lot of people!
