Battlesnake API Version 1 was released in May 2020 and is the new standard which all Battlesnakes should be implemented with. At this point, new feature development on play.battlesnake.com now depends on API Version 1 features in order to work.
Starting on October 12th, 2020 we will begin phasing out support for Version 0 of the Battlesnake API on play.battlesnake.com. All developers should upgrade their Battlesnakes to Version 1 of the API in order to keep accessing all the features of the site. We have provided a Migrating to API Version 1 guide to assist you with the upgrade.
Games created with API Version 0 Battlesnakes will no longer show user defined customizations such as head, tail and color selections. Instead, the default head and tail will be used and a randomized color will be provided.
API Version 0 Battlesnakes can no longer be used to attempt challenges and cannot be entered into competition division or arenas.
API Version 0 Battlesnakes will be removed from the Global arena and can no longer be entered into the ranked arena.
Support for Version 0 of the Battlesnake API will be removed from the engine. Users will no longer be able to create games using Version 0 Battlesnakes on play.battlesnake.com.
