- Update to 3.1.1:
* Source distribution packaging issue ([392]). Thanks yurivict@GitHub.
* Fixed RREL lookup in case of multi-meta models (some special cases were not
handled correctly; [#379]).
* Fixed test suite invocation to use `pytest` over `py.test` that stopped
working in pytest-7.2.0. ([#389]). Thanks mgorny@GitHub.
* Changed separator in obj. rule refs from `|` to `:`. Old separator
will still be allowed until version 4.0. ([#385], [#384])
* Removed the dependency on `future` package ([#388]). Thanks mgorny@GitHub.
* Removed vendored `six` library. We don't need 2.x support anymore. Thanks
davidchall@GitHub for reporting the issue ([#390]).
