## [23.1.0]

### Added

- Add prototype pollution validation for `signTypedData` methods (V1, V3, V4) to block dangerous properties (`__proto__`, `constructor`, `prototype`, etc.) in message data. ([#7732](https://github.com/MetaMask/core/pull/7732))

### Changed

- Bump `@metamask/json-rpc-engine` from `^10.2.0` to `^10.2.1` ([#7642](https://github.com/MetaMask/core/pull/7642))

## [23.0.0]

### Added

- Support for `wallet_getSupportedExecutionPermissions` and `wallet_getGrantedExecutionPermissions` RPC methods ([#7603](https://github.com/MetaMask/core/pull/7603))

### Changed

- Upgrade `@metamask/utils` from `^11.8.1` to `^11.9.0` ([#7511](https://github.com/MetaMask/core/pull/7511))
- **BREAKING:** Changed `wallet_requestExecutionPermissions` to comply with 7715 spec revisions.

## [22.0.1]

### Fixed

- Include `WalletContext` in EIP-7715 requests ([#7331](https://github.com/MetaMask/core/pull/7331))

## [22.0.0]

### Added

- Add new function `providerAsMiddlewareV2` for converting an `InternalProvider` into a `JsonRpcEngine` v2-compatible middleware ([#7138](https://github.com/MetaMask/core/pull/7138))

### Changed

- **BREAKING:** Migrate all middleware from `JsonRpcEngine` to `JsonRpcEngineV2` ([#7065](https://github.com/MetaMask/core/pull/7065))
  - To continue using this package with the legacy `JsonRpcEngine`, use the `asLegacyMiddleware` backwards compatibility function.
- **BREAKING:** Change the signatures of hooks for `createWalletMiddleware` ([#7065](https://github.com/MetaMask/core/pull/7065))
  - To wit:
    - `getAccounts` takes an origin argument (`string`) instead of a `JsonRpcRequest`
    - `processDecryptMessage` and `processEncryptionPublicKey` take a `MessageRequest` from `@metamask/message-manager` instead of `JsonRpcRequest`
    - `processPersonalMessage`, `processTransaction`, `processSignTransaction`, `processTypedMessage`, `processTypedMessageV3` and `processTypedMessageV4` take a `context` as the third argument, before any other arguments
  - Be advised that request objects are now deeply frozen, and cannot be mutated.
- **BREAKING:** Use `InternalProvider` instead of `SafeEventEmitterProvider` ([#6796](https://github.com/MetaMask/core/pull/6796))
  - Wherever a `SafeEventEmitterProvider` was expected, an `InternalProvider` is now expected instead.
- **BREAKING:** Stop retrying `undefined` results for methods that include a block tag parameter ([#7001](https://github.com/MetaMask/core/pull/7001))
  - The `retryOnEmpty` middleware will now throw an error if it encounters an `undefined` result when dispatching
    a request with a later block number than the originally requested block number.
  - In practice, this should happen rarely if ever.
- **BREAKING:** Migrate all uses of `interface` to `type` ([#6885](https://github.com/MetaMask/core/pull/6885))
- Bump `@metamask/message-manager` from `^14.0.0` to `^14.1.0` ([#7202](https://github.com/MetaMask/core/pull/7202))
- Bump `@metamask/json-rpc-engine` from `^10.1.1` to `^10.2.0` ([#7202](https://github.com/MetaMask/core/pull/7202))
- Bump `@metamask/eth-json-rpc-provider` from `^5.0.1` to `^6.0.0` ([#7202](https://github.com/MetaMask/core/pull/7202))
- Bump `@metamask/eth-block-tracker` from `^14.0.0` to `^15.0.0` ([#7202](https://github.com/MetaMask/core/pull/7202))

## [21.0.0]

### Changed

- **BREAKING:** Increase minimum Node.js version from `^18.16` to `^18.18` ([#6866](https://github.com/MetaMask/core/pull/6866))
- Bump `@metamask/eth-block-tracker` from `^12.2.1` to `^14.0.0` ([#6866](https://github.com/MetaMask/core/pull/6866), [#6883](https://github.com/MetaMask/core/pull/6883))
- Bump `@metamask/network-controller` from `^24.2.2` to `^24.3.0` ([#6883](https://github.com/MetaMask/core/pull/6883))
- This package was migrated from `MetaMask/eth-json-rpc-middleware` to the
  `MetaMask/core` monorepo.
