Breaking Change: Added a version for snapshots.
Breaking Change: Removed the mocksPattern configuration option, it never worked correctly.
Breaking Change: Renamed testPathDirs to roots to avoid confusion when configuring Jest.
Breaking Change: Updated printing of React elements to cause fewer changes when props change.
Breaking Change: Updated snapshot format to properly escape data.
Fixed --color to be recognized correctly again.

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.
