0.9.0 (2022-11-17)
==================
Features
--------
- A new reporter hook ``rejecting_candidate`` is added, replacing ``backtracking``.
The hook is called every time the resolver rejects a conflicting candidate before
trying out the next one in line.
Bug Fixes
---------
- Some valid states that were previously rejected are now accepted. This affects
states where multiple candidates for the same dependency conflict with each
other. The ``information`` argument passed to
``AbstractProvider.get_preference`` may now contain empty iterators. This has
always been allowed by the method definition but it was previously not possible
in practice.
