This release improves the behaviour of :func:`~hypothesis.strategies.builds` and :func:`~hypothesis.strategies.from_type` in certain situations involving decorators (:issue:`2495` and :issue:`3029`).
6.21.0
-------------------
This release introduces strategies for array/tensor libraries adopting the `Array API standard <https://data-apis.org/>`__ (:issue:`3037`). They are available in :ref:`the hypothesis.extra.array_api extra <array-api>`, and work much like the existing :ref:`strategies for NumPy <hypothesis-numpy>`.
6.20.1
-------------------
This patch fixes :issue:`961`, where calling ``given()`` inline on a bound method would fail to handle the ``self`` argument correctly.
6.20.0
-------------------
This release allows :func:`~hypothesis.strategies.slices` to generate ``step=None``, and fixes an off-by-one error where the ``start`` index could be equal to ``size``. This works fine for all Python sequences and Numpy arrays, but is undefined behaviour in the `Array API standard <https://data-apis.org/>`__ (see :pull:`3065`).
6.19.0
-------------------
This release makes :ref:`stateful testing <stateful>` more likely to tell you if you do something unexpected and unsupported:
- The :obj:`~hypothesis.HealthCheck.return_value` health check now applies to :func:`~hypothesis.stateful.rule` and :func:`~hypothesis.stateful.initialize` rules, if they don't have ``target`` bundles, as well as :func:`~hypothesis.stateful.invariant`. - Using a :func:`~hypothesis.stateful.consumes` bundle as a ``target`` is deprecated, and will be an error in a future version.
If existing code triggers these new checks, check for related bugs and misunderstandings - these patterns *never* had any effect.
6.18.0
-------------------
This release teaches :func:`~hypothesis.strategies.from_type` a neat trick: when resolving an :obj:`python:typing.Annotated` type, if one of the annotations is a strategy object we use that as the inferred strategy. For example:
