## [Unreleased]


## [0.8.5] - 2016-09-27

### Fixed
- Fixed all remaining issues resulting in Flow errors when `fbjs` is a dependency of a dependency.

### Removed
- Removed now extraneous `flow/lib/Promise.js`.

## [0.8.4] - 2016-08-19

### Changed
- Moved `try/catch` in `warning` module to helper function to prevent deopts.


## [0.8.3] - 2016-05-25

### Added
- `Deferred`: added `Deferred.prototype.catch` to avoid having to call this directly on the Promise.
- `UnicodeUtilsExtra`: added several methods for escaping strings.

### Changed
- More Flow annotations: `containsNode`, `emptyFunction`, `memoizeStringOnly`
- Added explicit `<any>` type arguments to in anticipation of a future Flow change requiring them.
- `Object.assign` calls now replaced with usage of `object-assign` module.

### Fixed

## [0.8.2] - 2016-05-05

### Removed
- Removed extraneous production dependency


## [0.8.1] - 2016-04-18

### Added
- We now include a `Promise` class definition in `flow/lib` to account for the changes in Flow v0.23 which removed non-spec methods. This will allow our code to continue typechecking while using these methods.


## [0.8.0] - 2016-04-04

### Added
- Several additional modules. Notably, a collection of Unicode utilities and many new `functional` helpers.
- `CSSCore`: added `matchesSelector` method

### Changed
- Copyright headers updated to reflect current boilerplate
- `@providesModule` headers removed from generated source code
- Flow files now contain relative requires, improving compatibility with Haste and CommonJS module systems

### Fixed
- `isEmpty`: Protect from breaking in environments without `Symbol` defined


## [0.7.2] - 2016-02-05

### Fixed
- `URI`: correctly store reference to value in constructor and return it when stringifying

### Removed
- Backed out rejection tracking for React Native `Promise` implementation. That code now lives in React Native.


## [0.7.1] - 2016-02-02

### Fixed

- Corrected require path issue for native `Promise` module


## [0.7.0] - 2016-01-27

### Added
- `Promise` for React Native with rejection tracking in `__DEV__` and a `finally` method
- `_shouldPolyfillES6Collection`: check if ES6 Collections need to be polyfilled.

### Removed
- `toArray`: removed in favor of using `Array.from` directly.

### Changed
- `ErrorUtils`: Re-uses any global instance that already exists
- `fetch`: Switched to `isomorphic-fetch` when a global implementation is missing
- `shallowEqual`: handles `NaN` values appropriately (as equal), now using `Object.is` semantics


## [0.6.1] - 2016-01-06

### Changed
- `getActiveElement`: no longer throws in non-browser environment (again)


## [0.6.0] - 2015-12-29

### Changed
- Flow: Original source files in `fbjs/flow/include` have been removed in favor of placing original files alongside compiled files in lib with a `.flow` suffix. This requires Flow version 0.19 or greater and a change to `.flowconfig` files to remove the include path.


## [0.5.1] - 2015-12-13

### Added
- `base62` module


## [0.5.0] - 2015-12-04

### Changed

- `getActiveElement`: No longer handles a non-existent `document`


## [0.4.0] - 2015-10-16

### Changed

- `invariant`: Message is no longer prefixed with "Invariant Violation: ".


## [0.3.2] - 2015-10-12

### Added
- Apply appropriate transform (`loose-envify`) when bundling with `browserify`


## [0.3.1] - 2015-10-01

### Fixed
- Ensure the build completes correctly before packaging


## [0.3.0] - 2015-10-01

### Added
- More modules: `memoizeStringOnly`, `joinClasses`
- `UserAgent`: Query information about current user agent

### Changed
- `fetchWithRetries`: Reject failure with an Error, not the response
- `getActiveElement`: no longer throws in non-browser environment
