I want to show the change log of the last update in my app. Is there API or a way to get those changes that appear on the Appstore in "What's new" section?
I would prefer this way to rolling my own server code.
you can get the text shown on the App Store using the iTunes Search API
https://www.apple.com/itunes/affiliates/resources/documentation/itunes-store-web-service-search-api.html
note that the example focuses on music! check out the code & the returned json to get the fields
https://github.com/Daij-Djan/DDUtils/tree/master/DDUtils-Common/model/DDAppStoreInfo%20%5Bios%2Bosx%5D
note that the code is NOT complete. the search returns a lot more info than what I use. Just use the right attribute
the objC code is my own implementation but I post it here as it serves to answer the question
