material

Breaking changes:

• snack-bar: matSnackBarHarness.getRole() replaced with .getAriaLive() due to using aria-live
  rather than the alert and status roles.
• Deprecated month constants from @angular/material/core have been
  removed. These have been accidentally published in the past while they
  were only intended for internal consumption in tests.
