3.18.5

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

This is a bugfix release for :func:`~hypothesis.strategies.integers`.
Previously the strategy would hit an internal assertion if passed non-integer
bounds for ``min_value`` and ``max_value`` that had no integers between them.
The strategy now raises InvalidArgument instead.

3.18.4

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

Release to fix a bug where mocks can be used as test runners under certain
conditions. Specifically, if a mock is injected into a test via pytest
fixtures or patch decorators, and that mock is the first argument in the
list, hypothesis will think it represents self and turns the mock
into a test runner. If this happens, the affected test always passes
because the mock is executed instead of the test body. Sometimes, it
will also fail health checks.

Fixes :issue:`491` and a section of :issue:`198`.
Thanks to Ben Peterson for this bug fix.

3.18.3

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

This release should improve the performance of some tests which
experienced a slow down as a result of the :ref:`3.13.0 <v3.13.0>` release.

Tests most likely to benefit from this are ones that make extensive
use of ``min_size`` parameters, but others may see some improvement
as well.

3.18.2

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

This release fixes a bug introduced in :ref:`3.18.0 <v3.18.0>`. If the arguments
``include_characters`` and ``exclude_characters`` to
:func:`~hypothesis.strategies.characters` contained overlapping elements, then an
``InvalidArgument`` exception would be raised.

Thanks to Zac Hatfield-Dodds for reporting and fixing this.

3.18.1

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

This is a bug fix release to fix :issue:`780`, where
:func:`~hypothesis.strategies.sets` and similar would trigger health check
errors if their element strategy could only produce one element (e.g.
if it was :func:`~hypothesis.strategies.just`).

3.18.0

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

This is a feature release:

* :func:`~hypothesis.strategies.characters` now accepts
``include_characters``, particular characters which will be added to those
it produces. (:issue:`668`)
* A bug fix for the internal function ``_union_interval_lists()``, and a rename
to ``_union_intervals()``. It now correctly handles all cases where intervals
overlap, and it always returns the result as a tuple for tuples.

Thanks to Alex Willmer for these.
