Previously failed tests are now always run first.
A new concurrent reporter shows currently running tests, a test summary, a progress bar and estimated remaining time if possible.
Improved CLI colors.
jest <pattern> is now case-insensitive.
Added it.only, it.skip, test.only, test.skip and xtest.
Added --testNamePattern=pattern or -t <pattern> to run individual tests in test files.
Jest now warns for duplicate mock files.
Pressing a, o, p, q or enter while tests are running in the watch mode, the test run will be interrupted.
--bail now works together with --watch.
Added test.concurrent for concurrent async tests.
Jest now automatically considers files and tests with the .jsx extension.
Added jest.clearAllMocks to clear all mocks manually.
Rewrote Jest's snapshot implementation. jest-snapshot can now be more easily integrated into other test runners and used in other projects.
This requires most snapshots to be updated when upgrading Jest.
Objects and Arrays in snapshots are now printed with a trailing comma.
Function names are not printed in snapshots any longer to reduce issues with code coverage instrumentation and different Node versions.
Snapshots are now sorted using natural sort order.
Snapshots are not marked as obsolete any longer when using fit or when an error is thrown in a test.
Finished migration of Jasmine matchers to the new Jest matchers.
Pretty print toHaveBeenLastCalledWith, toHaveBeenCalledWith, lastCalledWith and toBeCalledWith failure messages.
Added toBeInstanceOf matcher.
Added toContainEqual matcher.
Added toThrowErrorMatchingSnapshot matcher.
Improved moduleNameMapper resolution.
Module registry fixes.
Fixed invocation of the setupTestFrameworkScriptFile script to make it easier to use chai together with Jest.
Removed react-native special case in Jest's configuration.
Added --findRelatedTests <fileA> <fileB> cli option to run tests related to the specified files.
Added jest.deepUnmock to babel-plugin-jest-hoist.
Added jest.runTimersToTime which is useful together with fake timers.
Improved automated mocks for ES modules compiled with babel.

jest 15.0.0

See https://jestjs.io/blog/2016/09/01/jest-15
Jest by default now also recognizes files ending in .spec.js and .test.js as test files.
Completely replaced most Jasmine matchers with new Jest matchers.
Rewrote Jest's CLI output for test failures and summaries.
Added --env option to override the default test environment.
Disabled automocking, fake timers and resetting the module registry by default.
Added --watchAll, made --watch interactive and added the ability to update snapshots and select test patterns in watch mode.
Jest uses verbose mode when running a single test file.
Console messages are now buffered and printed along with the test results.
Fix testEnvironment resolution to prefer jest-environment-{name} instead of {name} only. This prevents a module collision when using jsdom as test environment.
moduleNameMapper now uses a resolution algorithm.
Improved performance for small test runs.
Improved API documentation.
Jest now works properly with directories that have special characters in them.
Improvements to Jest's own test infra by merging integration and unit tests. Code coverage is now collected for Jest.
Added global.global to the node environment.
Fixed babel-jest-plugin-hoist issues with functions called mock.
Improved jest-react-native preset with mocks for ListView, TextInput, ActivityIndicator and ScrollView.
Added collectCoverageFrom to collect code coverage from untested files.
Rewritten code coverage support.
