Features

• Move @testing-library/dom and @types/react-dom to peer dependencies (#​1305) (a4744fa)

BREAKING CHANGES

• @testing-library/dom was moved to a peer dependency and needs to be explicitly installed. This reduces the chance of having conflicting versions of @testing-library/dom installed that frequently caused bugs when used with @testing-library/user-event. We will also be able to allow new versions of @testing-library/dom being used without a SemVer major release of @testing-library/react by just widening the peer dependency.
  @types/react-dom needs to be installed if you're typechecking files using @testing-library/react.
