## [Unreleased]

## [4.1.0]
### Changed
- Update `@metamask/utils` to `^6.2.0` ([#1514](https://github.com/MetaMask/core/pull/1514))

## [4.0.1]
### Fixed
- Fix permissions RPC method types ([#1464](https://github.com/MetaMask/core/pull/1464))
  - The RPC method handlers were mistakenly typed as an array rather than a tuple

## [4.0.0]
### Changed
- **BREAKING:** Bump to Node 16 ([#1262](https://github.com/MetaMask/core/pull/1262))
- **BREAKING:** Update `@metamask/approval-controller` dependency and peer dependency
- The export `permissionRpcMethods` has a slightly different type; the second generic type variable of the `getPermissions` handler is now `undefined` rather than `void` ([#1372](https://github.com/MetaMask/core/pull/1372))
- Add `@metamask/utils` dependency ([#1275](https://github.com/MetaMask/core/pull/1275))
- Remove `@metamask/types` dependency ([#1372](https://github.com/MetaMask/core/pull/1372))
- Change type of constructor parameter `unrestrictedMethods` to be readonly ([#1395](https://github.com/MetaMask/core/pull/1395))

### Removed
- **BREAKING**: Remove namespaced permissions ([#1337](https://github.com/MetaMask/core/pull/1337))
  - Namespaced permissions are no longer supported. Consumers should replace namespaced permissions with equivalent caveat-based implementations.
- **BREAKING**: Remove `targetKey` concept ([#1337](https://github.com/MetaMask/core/pull/1337))
  - The target key/name distinction only existed to support namespaced permissions, which are removed as of this release. Henceforth, permissions only have "names".
  - The `targetKey` property of permission specifications has been renamed to `targetName`.

## [3.2.0]
### Added
- Allow restricting permissions by subject type ([#1233](https://github.com/MetaMask/core/pull/1233))

### Changed
- Move `SubjectMetadataController` to permission-controller package ([#1234](https://github.com/MetaMask/core/pull/1234))
- Update minimum `eth-rpc-errors` version from `4.0.0` to `4.0.2` ([#1215](https://github.com/MetaMask/core/pull/1215))

## [3.1.0]
### Added
- Add side-effects to permissions ([#1069](https://github.com/MetaMask/core/pull/1069))

## [3.0.0]
### Removed
- **BREAKING:** Remove `isomorphic-fetch` ([#1106](https://github.com/MetaMask/controllers/pull/1106))
  - Consumers must now import `isomorphic-fetch` or another polyfill themselves if they are running in an environment without `fetch`

## [2.0.0]
### Added
- Add `updateCaveat` action ([#1071](https://github.com/MetaMask/core/pull/1071))

### Changed
- **BREAKING:** Update `@metamask/network-controller` peer dependency to v3 ([#1041](https://github.com/MetaMask/controllers/pull/1041))
- Rename this repository to `core` ([#1031](https://github.com/MetaMask/controllers/pull/1031))
- Update `@metamask/controller-utils` package ([#1041](https://github.com/MetaMask/controllers/pull/1041))

## [1.0.2]
### Fixed
- This package will now warn if a required package is not present ([#1003](https://github.com/MetaMask/core/pull/1003))

## [1.0.1]
### Changed
- Relax dependencies on `@metamask/approval-controller`, `@metamask/base-controller` and `@metamask/controller-utils` (use `^` instead of `~`) ([#998](https://github.com/MetaMask/core/pull/998))

## [1.0.0]
### Added
- Initial release
  - As a result of converting our shared controllers repo into a monorepo ([#831](https://github.com/MetaMask/core/pull/831)), we've created this package from select parts of [`@metamask/controllers` v33.0.0](https://github.com/MetaMask/core/tree/v33.0.0), namely:
    - Everything in `src/permissions`

    All changes listed after this point were applied to this package following the monorepo conversion.
