Podcasts have come a long way from the days when they represented a novel way to fill up your iPod. There are now shows with seasons (like Serial), teasers and other trappings that you'd normally expect from TV. Simply speaking, podcast apps need to evolve to keep pace with listening habits... and Apple knows it. The company has detailed changes to the specs for iOS 11's Podcasts app that will make it easier to listen to shows as intended. The spec now supports seasons, and you'll have the option of downloading an entire season in one go if you're catching up. Creators can specify that a show is meant to be heard in chronological order, and they can tag podcasts as bonuses or teasers. And that's not all -- Apple is also helping podcasters make a better living through ads.
