May 2024: Remove deprecated APIs for August 2024 update

[kamranayub]

Fixes #32

As part of our migration from a 1:many to a many:many relationship between games and series (collections), we have migrated the data that used to be in the old collection field into the new collections field in the games endpoint. From collections, this can be found through the existing games filed. For the next 6 months (until August 2024) we will serve the data in both locations, then we will deprecate the collection field in the games endpoint

Discord: Furthermore, unrelated with the collections above, the field follows in the Game object is now deprecated and will be going away in future relapses. The main reason is that those data are not maintained anymore and would not produce accurate insights.

BREAKING CHANGES

• Remove Game.Collection property
• Remove Game.Follows property
• Change Platform.Category to a nullable (e.g. Steam VR)

Notes

• Confirmed that games will be available on Collection.Games field, so undid removal
