 # Changelog
 
+## 2.0.0
+
+Breaking change — major bump, required by the backend environments release.
+Every project now has exactly two environments, `staging` and `prod`, and the
+SDK key you configure decides which one the player belongs to. The environment
+never appears in the client API: it is resolved at login and carried inside the
+access and refresh tokens. Tokens issued before this release have no
+environment claim and are rejected with 401, so the first call after the
+backend upgrade refreshes, fails, clears the stored tokens and raises
+`AuthService.AuthStateChanged` with `RudderAuthState.SignedOut`. Log the player
+in again with `Auth.LoginWithDeviceAsync` / `LoginWithCustomAsync`.
+
+Quests, scenarios and offers are addressed by their slug instead of their id,
+because ids differ between staging and prod while slugs are stable. Renamed
+accordingly: `Quest.Id` is now `Quest.Slug`, `QuestsService.ClaimAsync` takes a
+quest slug, `ReportProgressAsync` returns the slugs of the completed quests
+(`ReportQuestProgressResponse.CompletedQuestSlugs`), `StoresService.PurchaseAsync`
+takes an offer slug and `Offer` carries a `Slug`, `QuestMetrics.PurchaseOffer`
+builds its metric from the offer slug, and every scenario-scoped type exposes
+`ScenarioSlug` instead of `ScenarioId` — `PendingEffect`, the effect objects,
+`ScenarioCompletedEffect`, `ScenarioFailedEffect`, the battle pass requests and
+`BattlePassService.GetProgressAsync`. Leaderboards, items and stores already
+used slugs and are unchanged.
+
+Also shipped here, previously committed but never published: the effects client
+reconciles against every `GET /sdk/v1/scenarios/pending` response, so a run that
+disappears server-side (finished elsewhere, expired after a promote) now emits
+`OnScenarioCompleted` instead of lingering; and `run_not_active` joins
+`unknown_run` and `run_expired` as a terminal rejection that drops the run and
+emits `OnScenarioFailed`.
+

+## Environments
+
+A project has two environments, `staging` and `prod`. The SDK key configured
+in `RudderClientOptions.ProjectKey` belongs to one of them, so the environment
+is resolved at login and carried inside the access and refresh tokens; nothing
+in the client API takes an environment argument, and a player created in one
+environment is invisible in the other. Content released only to `staging` is
+empty for a `prod` key and vice versa.

+Tokens issued before SDK 2.0.0 carry no environment claim and are rejected with
+401. The refresh pipeline then fails, clears the store and fires
+`AuthStateChanged(SignedOut)` — log the player in again.
