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'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't work.

3.39.0

---

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

---

3.38.9

---

This is a documentation release to improve the documentation of shrinking
behaviour for Hypothesis'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 <https://smarkets.com/>_.

---

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
