# Changelog

## 2.0.0

Breaking change — major bump, required by the backend environments release.
The module path gains the Go major-version suffix: import
`hub.rudder.build/rudder/rudder-go-sdk/v2` and pull it with
`go get hub.rudder.build/rudder/rudder-go-sdk/v2@latest`. Nothing else about
the import changes: the package is still `rudder`.

Admin keys are now per environment. A project has exactly two environments,
`staging` and `prod`, and each has its own Admin Key, so the key you configure
decides which environment every call reads and writes. There is no environment
option on the client or on any method, and there is nothing to migrate in code
— but the key itself changed: the old project Admin Key became the `prod` key
and a separate `staging` key was generated, both visible under project
Settings. Players are per environment too, so a player id from one environment
does not resolve in the other, and the same holds for wallets, inventory,
storage, counters, quests, runs, battle pass, purchases and leaderboard
entries.

Quests are addressed by slug, because ids differ between staging and prod
while slugs are stable. `PlayerQuestParameters.QuestID` is now
`PlayerQuestParameters.QuestSlug`, `PlayerQuestRef` carries `QuestSlug`
instead of `QuestID`, `PlayerQuest` reports `QuestSlug`, and `Quest`
(the catalog definition) gained `Slug` alongside its `ID`.
`Players.VerifyAuth` additionally returns `Environment`, which always matches
the admin key's environment.

Environment create, delete and merge, and project-level admin key
regeneration, were removed from the platform. This SDK never exposed them, so
nothing is gone from its surface.
