"""Deprecation messages and bits of code used elsewhere in the codebase that
is planned to be removed in the next pytest release.

Keeping it in a central location makes it easy to track what is deprecated and should
be removed when the time comes.

All constants defined in this module should be either instances of
:class:`PytestWarning`, or :class:`UnformattedWarning`
in case of warnings which need to format their messages.
