Apple has introduced new podcast categories to its dedicated section on the iTunes Music Store. The company is asking podcast makers to review these categories and make changes to their podcast feeds where required.

Apple sent an email detailing the changes to podcast-makers this week.

"We're sending you this email to let you know how to change your podcast feed to accommodate these changes," the company's email (which is available on Apple's website) says.

"Please note that we will support the use of the old category names for the next few months, so there is no immediate deadline for making these changes," Apple adds.

Among other changes, the company has removed three categories: International, Talk Radio and Public Radio.

Full details on the new categories and sub-categories are available in the note linked to above.
