3.44.16

---

This release improves test case reduction for recursive data structures.
Hypothesis now guarantees that whenever a strategy calls itself recursively
(usually this will happen because you are using :func:~hypothesis.strategies.deferred),
any recursive call may replace the top level value. e.g. given a tree structure,
Hypothesis will always try replacing it with a subtree.

Additionally this introduces a new heuristic that may in some circumstances
significantly speed up test case reduction - Hypothesis should be better at
immediately replacing elements drawn inside another strategy with their minimal
possible value.

3.44.15

:func:~hypothesis.strategies.from_type can now resolve recursive types
such as binary trees (:issue:1004). Detection of non-type arguments has
also improved, leading to better error messages in many cases involving
:pep:forward references <484forward-references>.
