- update to 1.0.1:
* Fix calls to opaque objects and use provider interface calls
instead. `#126
* Implement backjumping to significantly speed up the
resolution process by skipping over irrelevant parts of the
resolution search space. `#113
* 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.
* 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.
* edges that lead to the detected conflicts.
* Provide type stubs for most classes.

* A new reporter hook ``resolving_conflicts`` is added. The resolver triggers
* this hook when it detects conflicts in the dependency tree, and before it
* attempts to fix them. The hook accepts one single argument ``causes``, which
* is a list of ``(requirement, parent)`` 2-tuples that represents all the
* edges that lead to the detected conflicts.

- update to 0.8.0:
* Add ``backtrack_causes`` to ``get_preference``, which contains information
about the requirements involved in the most recent backtrack. This allows
the provider to utilise this information to tweak the ordering as well as
for recording/reporting conflicts.
* When merging a candidate's dependencies, make sure the merge target is
up-to-date within the loop, so the merge does not lose information when a
candidate returns multiple dependency specifications under one identifier
(e.g. specifyiung two dependencies ``a>1`` and ``a<2``, instead of one single
``a>1,<2`` dependency). `#80 <https://github.com/sarugaku/resolvelib/issues/80>`_
* Redesign ``get_preference()`` to include resolution state on dependencies
other than the currently working one, to allow the provider to better take
account of the global resolver knowledge and determine the best strategy. The
provider now can, for example, correctly calculate how far a dependency is
from the root node in the graph. `#74 <https://github.com/sarugaku/resolvelib/issues/74>`_
* A new argument ``incompatibilities`` is now passed to the ``find_matches()``
hook, which the provider must use to exclude matches from the return value.
* Redesign ``find_matches()`` to include resolution state on dependencies other
than the currently working one, to handle usages that need to return candidates
based on non-local states. One such example is PEP 508 direct URLs specified
on a package, which need to be available to the same package specified with
extras (which would have a different identifier).
* The resolver no longer relies on implicit candidate equality to detect
incompatibilities. This is done by an additional ``find_matches()`` argument;
see the *Features* section to learn more.
* Provide type stubs for most classes.
* Fix a state management bug that causes the resolver to enter an infinite loop
in certain backtracking cases.
* Fix a performance regression if ``find_matches()`` returns a non-built-in sequence instance.
* ``find_matches()`` now may return a ``Callable[[], Iterator[Candidate]]`` to

- Update to 0.3.0
* Provide both the requirements and their parents as exceptiondata for the
``ResolutionImpossible`` exception, via a ``causes`` attribute that replaces
the previous ``requirements`` attribute.
* Make resolver backtrack when none of the candidates requested for a package
are able to resolve due to them requesting unworkable requirements, or a
package has no candidates at all. Previously the resolver would give up on the
spot.
* Ensure the result returned by the resolver only contains candidates that are
actually needed. This is done by tracing the graph after resolution completes,
snipping nodes that don’t have a route to the root.
