Hypothesis

------------------

This is a bug fix release.

* Hypothesis now runs cleanly in -B and -BB modes, avoiding mixing bytes and unicode.
* :class:`python:unittest.TestCase` tests would not have shown up in the new statistics mode. Now they
do.
* Similarly, stateful tests would not have shown up in statistics and now they do.
* Statistics now print with pytest node IDs (the names you'd get in pytest verbose mode).

------------------

This is a feature release.

* :func:`~hypothesis.strategies.fractions` and :func:`~hypothesis.strategies.decimals` strategies now support min_value and max_value
parameters. Thanks go to Anne Mulhern for the development of this feature.
* The Hypothesis pytest plugin now supports a ``--hypothesis-show-statistics`` parameter
that gives detailed statistics about the tests that were run. Huge thanks to
Jean-Louis Fuchs and Adfinis-SyGroup for funding the development of this feature.
* There is a new :func:`~hypothesis.event` function that can be used to add custom statistics.

Additionally there have been some minor bug fixes:

* In some cases Hypothesis should produce fewer duplicate examples (this will mostly
only affect cases with a single parameter).
* :pypi:`pytest` command line parameters are now under an option group for Hypothesis (thanks
to David Keijser for fixing this)
* Hypothesis would previously error if you used :pep:`3107` function annotations on your tests under
Python 3.4.
* The repr of many strategies using lambdas has been improved to include the lambda body
(this was previously supported in many but not all cases).

------------------

This is a bug fix release, fixing a number of problems with the settings system:

* Test functions defined using :func:`given <hypothesis.given>` can now be called from other threads
(:issue:`337`)
* Attempting to delete a settings property would previously have silently done
the wrong thing. Now it raises an AttributeError.
* Creating a settings object with a custom database_file parameter was silently
getting ignored and the default was being used instead. Now it's not.

------------------

This is a bug fix release for a single bug:

* On Windows when running two Hypothesis processes in parallel (e.g. using
:pypi:`pytest-xdist`) they could race with each other and one would raise an exception
due to the non-atomic nature of file renaming on Windows and the fact that you
can't rename over an existing file. This is now fixed.

------------------

This release is entirely provided by `Lucas Wiman <https://github.com/lucaswiman>`_:

Strategies constructed by the Django extra
will now respect much more of Django's validations out of the box.
Wherever possible, :meth:`~django:django.db.models.Model.full_clean` should
succeed.

In particular:

* The max_length, blank and choices kwargs are now respected.
* Add support for DecimalField.
* If a field includes validators, the list of validators are used to filter the field strategy.

------------------

This release went wrong and is functionally equivalent to :ref:`3.2.0 <v3.2.0>`. Ignore it.
