This patch fixes :func:`~hypothesis.strategies.from_type` with the :pypi:`typing_extensions` ``Literal`` backport on Python 3.6.
5.43.9
Not secure
-------------------
This patch fixes :issue:`2722`, where certain orderings of :func:`~hypothesis.strategies.register_type_strategy`, :class:`~python:typing.ForwardRef`, and :func:`~hypothesis.strategies.from_type` could trigger an internal error.
5.43.8
Not secure
-------------------
This patch makes some strategies for collections with a uniqueness constraint much more efficient, including ``dictionaries(keys=sampled_from(...), values=..)`` and ``lists(tuples(sampled_from(...), ...), unique_by=lambda x: x[0])``. (related to :issue:`2036`)
5.43.7
Not secure
-------------------
This patch extends our faster special case for :func:`~hypothesis.strategies.sampled_from` elements in unique :func:`~hypothesis.strategies.lists` to account for chains of ``.map(...)`` and ``.filter(...)`` calls (:issue:`2036`).
5.43.6
Not secure
-------------------
This patch improves the type annotations on :func:`~hypothesis.assume` and :func:`reproduce_failure() <hypothesis.reproduce_failure>`.
5.43.5
Not secure
-------------------
This patch updates our copyright headers to include 2021. Happy new year!
