This release fixes a small internal bug in shrinking which could have caused it to perform slightly more tests than were necessary. Fixing this shouldn't have much effect but it will make shrinking slightly faster.
4.56.2
Not secure
-------------------
This release removes an internal heuristic that was no longer providing much benefit. It is unlikely that there will be any user visible effect.
4.56.1
Not secure
-------------------
This release further improves the optimisation algorithm for :ref:`targeted property-based testing <targeted-search>`.
4.56.0
Not secure
-------------------
This release enables deprecation warnings even when the :obj:`~hypothesis.settings.verbosity` setting is ``quiet``, in preparation for Hypothesis 5.0 (:issue:`2218`).
Warnings can still be filtered by the standard mechanisms provided in the standard-library :mod:`python:warnings` module.
4.55.4
Not secure
-------------------
This release improves Hypothesis's management of the set of test cases it tracks between runs. It will only do anything if you have the :obj:`~hypothesis.Phase.target` phase enabled and an example database set. In those circumstances it should result in a more thorough and faster set of examples that are tried on each run.
4.55.3
Not secure
-------------------
This release makes Hypothesis better at generating test cases where generated values are duplicated in different parts of the test case. This will be especially noticeable with reasonably complex values, as it was already able to do this for simpler ones such as integers or floats.
