As described by Libsyn, the Podcasts Connect portal lets users submit new podcasts and manage existing podcasts using their Apple IDs. Uploading a podcast is as simple as entering an RSS feed URL and there are new features that make it easier for podcasters to update their content.
Refreshing an RSS feed via the portal will allow for quick fixes and changes to be synced to iTunes, and there are tools for hiding podcasts and deleting them from the iTunes podcast directory. The portal will also give podcasters information on the current status of their uploaded podcasts.
Apple has been sending emails to customers who upload podcasts to let them know about the new Podcasts Connect tool, which is also accompanied by improved support resources for podcast providers and HTTPS support for the podcast metadata, cover art, and episode files.
