### Added

- Add Tempo Mainnet (`4217`/`0x1079`) and Tempo Moderato Testnet (`42431`/`0xa5bf`) support ([#8258](https://github.com/MetaMask/core/pull/8258))

- Add `0x1079` and `0xa5bf` to `SPOT_PRICES_SUPPORT_INFO` in `codefi-v2.ts`
- Add `0x1079` and `0xa5bf` to `chainIdToNativeTokenAddress` in `codefi-v2.ts`
- Add `0xa5bf` (only Tempo Testnet) to `MULTICALL_CONTRACT_BY_CHAINID` in `multicall.ts`

- `TokenBalancesController` batches rapid `updateBalances` calls: multiple requests within a short timeframe are coalesced and processed once, reducing redundant balance fetches ([#8246](https://github.com/MetaMask/core/pull/8246))

### Changed

- **BREAKING:** `AssetListState` type now requires a top-level `selectedAccountGroup` property, matching the updated `AccountTreeControllerState` shape where `selectedAccountGroup` was moved out of `accountTree` ([#8245](https://github.com/MetaMask/core/pull/8245))
