v3.0.1

Welcome Jest 21.

If you want to migrate just make sure to remove config entry from your object, for example:

With gulp-jest v2 you did:

gulp.src('__tests__')
  .pipe(jest({
    config: {
      rootDir: process.cwd(),
      testEnvironment: 'node',
    }
  }))

now you do:

gulp.src('__tests__')
  .pipe(jest({
    rootDir: process.cwd(),
    testEnvironment: 'node',
  }))
