 ### Fixes
 
+- `[jest-cli]` Pass `globalConfig` as a parameter to `globalSetup` and `globalTeardown` functions ([#6486](https://github.com/facebook/jest/pull/6486))
 - `[jest-config]` Add missing options to the `defaults` object ([#6428](https://github.com/facebook/jest/pull/6428))
 - `[expect]` Using symbolic property names in arrays no longer causes the `toEqual` matcher to fail ([#6391](https://github.com/facebook/jest/pull/6391))
 - `[expect]` `toEqual` no longer tries to compare non-enumerable symbolic properties, to be consistent with non-symbolic properties. ([#6398](https://github.com/facebook/jest/pull/6398))
