0.8.2

• Performance improvements.
• jest now uses chalk instead of its own colors implementation.

0.8.1

• --bail now reports with the proper error code.
• Fixed loading of the setup file when using jasmine2.
• Updated jsdom to 7.2.0.

0.8.0

• Added optional support for jasmine2 through the testRunner config option.
• Fixed mocking support for Map, WeakMap and Set.
• node was added to the defaults in moduleFileExtensions.
• Updated the list of node core modules that are properly being recognized by the module loader.

0.7.1

• Correctly map process.on into jsdom environments, fixes a bug introduced in jest 0.7.0.

0.7.0

• Fixed a memory leak with test contexts. Jest now properly cleans up test environments after each test. Added --logHeapUsage to log memory usage after each test. Note: this is option is meant for debugging memory leaks and might significantly slow down your test run.
• Removed mock-modules, node-haste and mocks virtual modules. This is a breaking change of undocumented public API. Usage of this API can safely be automatically updated through an automated codemod:
• Example: http://astexplorer.net/#/zrybZ6UvRA
• Codemod: https://github.com/cpojer/js-codemod/blob/master/transforms/jest-update.js
• jscodeshift: https://github.com/facebook/jscodeshift
• Removed navigator.onLine and mockSetReadOnlyProperty from the global jsdom environment. Use window.navigator.onLine = true; in your test setup and Object.defineProperty instead.

0.6.1

• Updated jsdom to 7.0.2.
• Use the current working directory as root when passing a jest config from the command line.
• Updated the React examples and getting started guide
• Modules now receive a module.parent field so unmocked modules don't assume they are run directly any longer.

0.6.0

• jest now reports the number of tests that were run instead of the number of test files.
• Added a --json option to print test results as JSON.
• Changed the preprocessor API. A preprocessor now receives the script, file and config. The cache key function receives the script, file and stringified config to be able to create consistent hashes.
• Removed node-worker-pool in favor of node-worker-farm (#540).
• toEqual now also checks the internal class name of an object. This fixes invalid tests like expect([]).toEqual({}) which were previously passing.
• Added the option to provide map modules to stub modules by providing the moduleNameMapper config option.
• Allow to specify a custom testRunner in the configuration (#531).
• Added a --no-cache option to make it easier to debug preprocessor scripts.
• Fix code coverage on windows (#499).

0.5.6

• Cache test run performance and run slowest tests first to maximize worker utilization
• Update to jsdom 6.5.0

0.5.5

• Improve failure stack traces.
• Fix syntax error reporting.
• Add --watch option (#472).

0.5.2
