@@ -43,6 +43,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **BREAKING:** Standardize names of `AccountTrackerController` messenger action types ([#8164](https://github.com/MetaMask/core/pull/8164))
   - All existing types for messenger actions have been renamed so they include `Controller` (e.g. `AccountTrackerUpdateNativeBalancesAction` -> `AccountTrackerControllerUpdateNativeBalancesAction`). You will need to update imports appropriately.
   - This change only affects the types. The action type strings themselves have not changed, so you do not need to update the list of actions you pass when initializing `AccountTrackerController` messengers.
+- Remove hardcoded `supportedNftDetectionNetworks` chain allowlist from `NftDetectionController`; the NFT API now returns an empty array for unsupported chains instead of an error, so chain gating is no longer needed in the client ([#8180](https://github.com/MetaMask/core/pull/8180))
+- `NftDetectionController` now skips the NFT API call entirely when all provided chain IDs are non-EVM (decimal `0`), returning an empty result immediately ([#8180](https://github.com/MetaMask/core/pull/8180))
+- Update `ReservoirResponse.continuation` type from `string` to `string | null` to match the NFT API response shape ([#8180](https://github.com/MetaMask/core/pull/8180))
