Description: 

The default display in Views was previously referred to as both the "Default" and the "Master" display.
These have now been unified as the "Default" display.

Existing views config will not be affected, only new views. This will affect views created during tests, update your assertions if you have any referring to "Master".

Additionally, the ui.show.master_display setting of Views is now ui.show.default_display.
This has an update hook.
