## Changelogs


### eliot 1.2.0 -> 1.3.0

>### 1.3.0









### hypothesis 3.38.5 -> 3.40.1

>### 3.40.1

>-------------------

>This release makes two changes:

>* It makes the calculation of some of the metadata that Hypothesis uses for
>  shrinking occur lazily. This should speed up performance of test case
>  generation a bit because it no longer calculates information it doesn&#39;t need.
>* It improves the shrinker for certain classes of nested examples. e.g. when
>  shrinking lists of lists, the shrinker is now able to concatenate two
>  adjacent lists together into a single list. As a result of this change,
>  shrinking may get somewhat slower when the minimal example found is large.

>-------------------


>### 3.40.0

>-------------------

>This release improves how various ways of seeding Hypothesis interact with the
>example database:

>* Using the example database with :func:`~hypothesis.seed` is now deprecated.
>  You should set ``database=None`` if you are doing that. This will only warn
>  if you actually load examples from the database while using ``seed``.
>* The :attr:`~hypothesis.settings.derandomize` will behave the same way as
>  ``seed``.
>* Using ``--hypothesis-seed`` will disable use of the database.
>* If a test used examples from the database, it will not suggest using a seed
>  to reproduce it, because that won&#39;t work.

>This work was funded by `Smarkets &lt;https://smarkets.com/&gt;`_.

>-------------------


>### 3.39.0

>-------------------

>This release adds a new health check that checks if the smallest &quot;natural&quot;
>possible example of your test case is very large - this will tend to cause
>Hypothesis to generate bad examples and be quite slow.

>This work was funded by `Smarkets &lt;https://smarkets.com/&gt;`_.

>-------------------


>### 3.38.9

>-------------------

>This is a documentation release to improve the documentation of shrinking
>behaviour for Hypothesis&#39;s strategies.

>-------------------


>### 3.38.8

>-------------------

>This release improves the performance of
>:func:`~hypothesis.strategies.characters` when using ``blacklist_characters``
>and :func:`~hypothesis.strategies.from_regex` when using negative character
>classes.

>The problems this fixes were found in the course of work funded by
>`Smarkets &lt;https://smarkets.com/&gt;`_.

>-------------------


>### 3.38.7

>-------------------

>This is a patch release for :func:`~hypothesis.strategies.from_regex`, which
>had a bug in handling of the :obj:`python:re.VERBOSE` flag (:issue:`992`).
>Flags are now handled correctly when parsing regex.

>-------------------


>### 3.38.6

>-------------------

>This patch changes a few byte-string literals from double to single quotes,
>thanks to an update in :pypi:`unify`.  There are no user-visible changes.

>-------------------






### pyopenssl 17.4.0 -> 17.5.0

>### 17.5.0

>-------------------


>Backward-incompatible changes:
>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

>* The minimum ``cryptography`` version is now 2.1.4.


>Deprecations:
>^^^^^^^^^^^^^

>*none*


>Changes:
>^^^^^^^^

>- Fixed a potential use-after-free in the verify callback and resolved a memory leak when loading PKCS12 files with ``cacerts``.
>  `723 &lt;https://github.com/pyca/pyopenssl/pull/723&gt;`_
>- Added ``Connection.export_keying_material`` for RFC 5705 compatible export of keying material.
>  `725 &lt;https://github.com/pyca/pyopenssl/pull/725&gt;`_

>----
