 ## [Unreleased]
 
+## [3.0.0]
+
+### Added
+
+- Add key Multichain API methods ([#4813](https://github.com/MetaMask/core/pull/4813))
+  - Adds `getInternalScopesObject` and `getSessionScopes` helpers for transforming between `NormalizedScopesObject` and `InternalScopesObject`.
+  - Adds handlers for `wallet_getSession`, `wallet_invokeMethod`, and `wallet_revokeSession` methods.
+  - Adds `multichainMethodCallValidatorMiddleware` for validating Multichain API method params as defined in @metamask/api-specs.
+  - Adds `MultichainMiddlewareManager` to multiplex a request to other middleware based on requested scope.
+  - Adds `MultichainSubscriptionManager` to handle concurrent subscriptions across multiple scopes.
+  - Adds `bucketScopes` which groups the scopes in a `NormalizedScopesObject` based on if the scopes are already supported, could be supported, or are not supportable.
+  - Adds `getSupportedScopeObjects` helper for getting only the supported methods and notifications from each `NormalizedScopeObject` in a `NormalizedScopesObject`.
+
