Episodic or Serial | Podcast Publication Type

There are two kind of publication for a podcast:

Episodic
The classic podcast format is where the latest episode always appears first in the feed. Optionally, episode numbers can be included, which some podcast apps display at the start of the episode title.

Serial
Allows you to organize your podcast into seasons.
⚠️ This setting cannot be changed once the podcast is published.
