4.55.2

Not secure
-------------------

This release expands the set of test cases that Hypothesis saves in its
database for future runs to include a representative set of "structurally
different" test cases - e.g. it might try to save test cases where a given list
is empty or not.

Currently this is unlikely to have much user visible impact except to produce
slightly more consistent behaviour between consecutive runs of a test suite.
It is mostly groundwork for future improvements which will exploit this
functionality more effectively.

4.55.1

Not secure
-------------------

This patch fixes :issue:`2257`, where :func:`~hypothesis.strategies.from_type`
could incorrectly generate bytestrings when passed a generic
:class:`python:typing.Sequence` such as ``Sequence[set]``.

4.55.0

Not secure
-------------------

This release adds database support for :ref:`targeted property-based testing <targeted-search>`,
so the best examples based on the targeting will be saved and reused between runs.
This is mostly laying groundwork for future features in this area, but
will also make targeted property-based tests more useful during development,
where the same tests tend to get run over and over again.

If :obj:`~hypothesis.settings.max_examples` is large, this may increase memory
usage significantly under some circumstances, but these should be relatively
rare.

This release also adds a dependency on the :pypi:`sortedcontainers` package.

4.54.2

Not secure
-------------------

This release improves the optimisation algorithm for :ref:`targeted property-based testing <targeted-search>`,
so that it will find higher quality results more reliably. Specifically, in cases where it would previously have got near a local optimum,
it will now tend to achieve the locally optimal value.

4.54.1

Not secure
-------------------

This release is mostly internal changes in support of better testing of the
core engine. You are unlikely to see much effect, although some internal
heuristics have changed slightly.

4.54.0

Not secure
-------------------

This release adds a dedicated phase for :ref:`targeted property-based testing <targeted-search>`,
and (somewhat) improves the targeting algorithm so that it will find higher quality results more reliably.
This comes at a cost of making it more likely to get stuck in a local optimum.
