## [Unreleased]

## [10.3.0]
### Changed
- Simplify `rpcService` parameter type of `createInfuraMiddleware` ([#127](https://github.com/MetaMask/eth-json-rpc-infura/pull/127))
- Bump `@metamask/eth-json-rpc-provider` from `^4.1.7` to `^5.0.0` ([#126](https://github.com/MetaMask/eth-json-rpc-infura/pull/126))
- Bump `@metamask/json-rpc-engine` from `^10.0.2` to `^10.1.0` ([#126](https://github.com/MetaMask/eth-json-rpc-infura/pull/126))

## [10.2.0]
### Added
- Add `sei-mainnet` and `sei-testnet` as Infura supported network ([#117](https://github.com/MetaMask/eth-json-rpc-infura/pull/117))

## [10.1.1]
### Fixed
- Fix middleware so that non-standard JSON-RPC error responses are no longer treated as successful responses ([#123](https://github.com/MetaMask/eth-json-rpc-infura/pull/123))
  - A "non-standard" error response is one with an `error` field but where there are more properties in the error object than expected

## [10.1.0]
### Added
- Add a way to pass an RPC service to `createInfuraMiddleware` ([#116](https://github.com/MetaMask/eth-json-rpc-infura/pull/116))
  - The new, recommended function signature is now `createInfuraMiddleware({ rpcService: AbstractRpcService; options?: { source?: string; headers?: HeadersInit } })`, where `AbstractRpcService` matches the same interface from `@metamask/network-controller`
  - This allows us to support automatic failover to a secondary node when the network goes down

### Changed
- Bump dependencies to remove pre-11.x versions of `@metamask/utils` from dependency tree ([#118](https://github.com/MetaMask/eth-json-rpc-infura/pull/118))
  - Bump `@metamask/eth-json-rpc-provider` from `^4.1.5` to `^4.1.7`
  - Bump `@metamask/json-rpc-engine` from `^10.0.0` to `^10.0.2`
  - Bump `@metamask/rpc-errors` from `^7.0.0` to `^7.0.2`
  - Bump `@metamask/utils` from `^9.1.0` to `^11.1.0`

### Deprecated
- Deprecate passing an RPC endpoint to `createInfuraMiddleware` ([#116](https://github.com/MetaMask/eth-json-rpc-infura/pull/116))
  - See recommended function signature above
  - The existing signature `createInfuraMiddleware({ network?: InfuraJsonRpcSupportedNetwork; maxAttempts?: number; source?: string; projectId: string; headers?: Record<string, string>; })` will be removed in a future major version

## [10.0.0]
### Changed
- **BREAKING**: `@metamask/json-rpc-engine` from `^7.1.1` to `^10.0.0` ([#112](https://github.com/MetaMask/eth-json-rpc-infura/pull/112))
