## [Unreleased]

## [3.2.0]
### Changed
- When deriving state, skip properties with invalid metadata  ([#1529](https://github.com/MetaMask/core/pull/1529))
  - The previous behavior was to throw an error
  - An error is thrown in a timeout handler so that it can still be captured in the console, and by global unhandled error handlers.
- Update `@metamask/utils` to `^6.2.0` ([#1514](https://github.com/MetaMask/core/pull/1514))

## [3.1.0]
### Changed
- Prevent event publish from throwing error ([#1475](https://github.com/MetaMask/core/pull/1475))
  - The controller messenger will no longer throw when an event subscriber throws an error. Calls to `publish` (either within controllers or on a messenger instance directly) will no longer throw errors.
  - Errors are thrown in a timeout handler so that they can still be logged and captured.

## [3.0.0]
### Changed
- **BREAKING:** Bump to Node 16 ([#1262](https://github.com/MetaMask/core/pull/1262))
- Replace `@metamask/controller-utils` dependency with `@metamask/utils` ([#1370](https://github.com/MetaMask/core/pull/1370))

## [2.0.0]
### 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`

## [1.1.2]
### Changed
- 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)) 

## [1.1.1]
### Changed
- Relax dependency on `@metamask/controller-utils` (use `^` instead of `~`) ([#998](https://github.com/MetaMask/core/pull/998))

## [1.1.0]
### Added
- Add `applyPatches` function to BaseControllerV2 ([#980](https://github.com/MetaMask/core/pull/980))

### Changed
- Action and event handler types are now exported ([#987](https://github.com/MetaMask/core/pull/987))
- Update `update` function to expose patches ([#980](https://github.com/MetaMask/core/pull/980))

## [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:
    - `src/BaseController.ts`
    - `src/BaseController.test.ts`
    - `src/BaseControllerV2.ts`
    - `src/BaseControllerV2.test.ts`
    - `src/ComposableController.ts`
    - `src/ComposableController.test.ts`
    - `src/ControllerMessenger.ts`
    - `src/ControllerMessenger.test.ts`

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