This PR updates hypothesis from 6.92.1 to 6.122.4.

Changelog

6.122.4

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

This patch improves generation performance for the provisional :func:`~hypothesis.provisional.domains` strategy, including its derivative strategies :func:`~hypothesis.provisional.urls` and :func:`~hypothesis.strategies.emails`.

6.122.3

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

This patch improves our error and warning messages.

- Add a warning for ``st.text("ascii")`` - you probably meant ``st.text(st.characters(codec="ascii"))``. Similarly for ``"utf-8"``.
- Recommend remedies in the error message of ``Unsatisfiable``.
- When ``given`` errors because it was given an extra keyword argument, and the keyword matches a setting name like ``max_examples``, recommend ``settings(max_examples=...)`` instead.

6.122.2

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

This patch updates some outdated external links in our documentation.

6.122.1

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

Fix :func:`~hypothesis.strategies.from_type`
on :class:`collections.abc.Callable` returning ``None``.

6.122.0

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

This release adds ``.span_start()`` and ``.span_end()`` methods
to our internal ``PrimitiveProvider`` interface, for use by
:ref:`alternative-backends`.

6.121.2

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

This patch updates our autoformatting tools, improving our code style without any API changes.

6.121.1

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

This release brings back the old representation of :class:`hypothesis.stateful.Bundle`, reverting most changes of `PR 4124 <https://github.com/HypothesisWorks/hypothesis/pull/4124>`_.

6.121.0

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

This release adds :class:`~hypothesis.database.BackgroundWriteDatabase`, a new database backend which defers writes on the wrapped database to a background thread. This allows for low-overhead writes in performance-critical environments like :ref:`fuzz_one_input <fuzz_one_input>`.

6.120.0

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

* This release changes our input distribution for low ``max_examples``. Previously, we capped the size of inputs when generating at least the first 10 inputs, with the reasoning that early inputs to a property should be small. However, this meant properties with ``max_examples=10`` would consistent entirely of small inputs. This patch removes the hard lower bound so that inputs to these properties are more representative of the input space.
* When a user requests an interactive input via ``strategy.example``, we generate and cache a batch of 100 inputs, returning the first one. This can be expensive for large strategies or when only a few examples are needed. This release improves the speed of ``strategy.example`` by lowering the batch size to 10.

6.119.4

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

This patch fixes a bug since :ref:`v6.99.13` where only interactively-generated values (via ``data.draw``) would be reported in the ``arguments`` field of our :doc:`observability output <observability>`. Now, all values are reported.

6.119.3

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

Hypothesis collects coverage information during the ``shrink`` and ``explain`` :ref:`phases <phases>` in order to show a more informative error message. On 3.12+, this uses :mod:`sys.monitoring`. This patch improves the performance of coverage collection on 3.12+ by disabling events we don't need.

6.119.2

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

This patch refactors some internals to prepare for future work using our IR (:issue:`3921`).

6.119.1

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

This patch migrates some more internals (around generating novel inputs) to the IR layer (:issue:`3921`).

6.119.0

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

This release improves Hypothesis' handling of ExceptionGroup - it's now able to detect marker detections if they're inside a  group and attempts to resolve them. Note that this handling is still a work in progress and might not handle edge cases optimally. Please open issues if you encounter any problems or unexpected behavior with it.

6.118.9

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

Internal refactorings in preparation for upcoming changes.

6.118.8

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

Internal renamings.

6.118.7

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

This patch removes some `` type: ignore`` comments following a :pypi:`mypy` update.

6.118.6

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

When Hypothesis replays examples from its test database that it knows were previously fully shrunk it will no longer try to shrink them again.

This should significantly speed up development workflows for slow tests, as the shrinking could contribute a significant delay when rerunning the tests.

In some rare cases this may cause minor reductions in example quality. This was considered an acceptable tradeoff for the improved test runtime.

6.118.5

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

This patch avoids computing some string representations we won't need,
giving a small speedup (part of :issue:`4139`).

6.118.4

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

This patch migrates the optimisation algorithm for :ref:`targeted property-based testing <targeted-search>` to our IR layer (:issue:`3921`). This should result in moderately different (and hopefully improved) exploration behavior in tests which use :func:`hypothesis.target`.

6.118.3

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

This patch adds more type hints to internal Hypothesis code.

6.118.2

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

This patch migrates the :obj:`~hypothesis.Phase.explain` :ref:`phase <phases>` to our IR layer (:issue:`3921`). This should improve both its speed and precision.

6.118.1

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

This patch updates some internals around how we determine an input is too large to finish generating.

6.118.0

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

The :func:`~hypothesis.provisional.urls` strategy no longer generates
URLs where the port number is 0.

This change is motivated by the idea that the generated URLs should, at least in
theory, be possible to fetch. The port number 0 is special; if a server binds to
port 0, the kernel will allocate an unused, and non-zero, port instead. That
means that it's not possible for a server to actually be listening on port 0.
This motivation is briefly described in the documentation for
:func:`~hypothesis.provisional.urls`.

Fixes :issue:`4157`.

Thanks to gmacon for this contribution!

6.117.0

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

This changes the behaviour of settings profiles so that if you reregister the currently loaded profile it will automatically reload it. Previously you would have had to load it again.

In particular this means that if you register a "ci" profile, it will automatically be used when Hypothesis detects you are running on CI.

6.116.0

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

Hypothesis now detects if it is running on a CI server and provides better default settings for running on CI in this case.

6.115.6

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

This patch changes the priority order of pretty printing logic so that a user
provided pretty printing method will always be used in preference to e.g.
printing it like a dataclass.

6.115.5

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

This patch restores diversity to the outputs of
:func:`from_type(type) <hypothesis.strategies.from_type>` (:issue:`4144`).

6.115.4

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

This release improves pretty printing of nested classes to include the outer class name in their printed representation.

6.115.3

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

This patch fixes a regression from :ref:`version 6.115.2 <v6.115.2>` where generating values from :func:`~hypothesis.strategies.integers` with certain values for ``min_value`` and ``max_value`` would error.

6.115.2

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

This release improves integer shrinking by folding the endpoint upweighting for :func:`~hypothesis.strategies.integers` into the ``weights`` parameter of our IR (:issue:`3921`).

If you maintain an alternative backend as part of our (for now explicitly unstable) :ref:`alternative-backends`, this release changes the type of the ``weights`` parameter to ``draw_integer`` and may be a breaking change for you.

6.115.1

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

This patch improves the performance of :func:`~hypothesis.strategies.from_type` with
`pydantic.types.condate <https://docs.pydantic.dev/latest/api/types/#pydantic.types.condate>`__
(:issue:`4000`).

6.115.0

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

This improves the formatting of dataclasses and attrs classes when printing
falsifying examples.

6.114.1

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

This patch upgrades remaining type annotations to Python 3.9 syntax.

6.114.0

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

This release drops support for Python 3.8, `which reached end of life on
2024-10-07 <https://devguide.python.org/versions/>`__.

6.113.0

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

This release adds ``hypothesis.errors.BackendCannotProceed``, an unstable API
for use by :ref:`alternative-backends`.

6.112.5

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

This release fixes a regression where :class:`hypothesis.stateful.Bundle` did not work properly with :ref:`flatmap <flatmap>` functionality (:issue:`4128`).

6.112.4

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

This patch tweaks the paths in ``example(...)`` patches, so that
both ``git apply`` and ``patch`` will work by default.

6.112.3

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

This release refactors internals of :class:`hypothesis.stateful.Bundle` to have a more consistent representation internally.

6.112.2

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

This patch fixes an internal error when the ``__context__``
attribute of a raised exception leads to a cycle (:issue:`4115`).

6.112.1

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

This patch removes a now-incorrect internal assertion about numpy's typing after recent numpy changes (currently only in numpy's nightly release).

6.112.0

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

This release adds support for variable-width bytes in our IR layer (:issue:`3921`), which should mean improved performance anywhere you use :func:`~hypothesis.strategies.binary`. If you maintain an alternative backend as part of our (for now explicitly unstable) :ref:`alternative-backends`, this release changes the ``draw_*`` interface and may be a breaking change for you.

6.111.2

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

This patch contains some internal code cleanup.  There is no user-visible change.

6.111.1

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

This patch improves shrinking in cases involving 'slips' from one strategy to another. Highly composite strategies are the most likely to benefit from this change.

This patch also reduces the range of :class:`python:datetime.datetime` generated by :func:`~hypothesis.extra.django.from_model` in order to avoid https://code.djangoproject.com/ticket/35683.

6.111.0

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

:ref:`alternative-backends` can now implement ``.observe_test_case()``
and ``observe_information_message()`` methods, to record backend-specific
metadata and messages in our :doc:`observability output <observability>`
(:issue:`3845` and `hypothesis-crosshair22
<https://github.com/pschanely/hypothesis-crosshair/issues/22>`__).

6.110.2

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

Support ``__default__`` field of :obj:`~python:typing.TypeVar`
and support the same from :pypi:`typing-extensions`
in :func:`~hypothesis.strategies.from_type`.

6.110.1

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

Add better error message for :obj:`!~python:typing.TypeIs` types
in :func:`~hypothesis.strategies.from_type`.

6.110.0

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

Support :obj:`~python:typing.LiteralString`
in :func:`~hypothesis.strategies.from_type`.

6.109.1

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

This patch makes progress towards adding type hints to our internal conjecture engine (:issue:`3074`).

6.109.0

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

This release allows using :obj:`~python:typing.Annotated`
and :obj:`!ReadOnly` types
for :class:`~python:typing.TypedDict` value types
with :func:`~hypothesis.strategies.from_type`.

6.108.10

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

This patch fixes compatibility with :pypi:`attrs==24.1.0 <attrs>`
on the nightly build of CPython, 3.14.0 pre-alpha (:issue:`4067`).

6.108.9

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

This patch removes an assertion which was in fact possible in rare circumstances involving a small number of very large draws.

6.108.8

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

This patch improves our example generation performance by adjusting our internal cache implementation.

6.108.7

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

This patch improves our pretty-printer for unusual numbers.

- Signalling NaNs are now represented by using the :mod:`struct` module
to show the exact value by converting from a hexadecimal integer

- CPython `limits integer-to-string conversions
<https://docs.python.org/3/library/stdtypes.html#integer-string-conversion-length-limitation>`__
to mitigate DDOS attacks.  We now use hexadecimal for very large
integers, and include underscore separators for integers with ten
or more digits.

6.108.6

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

This patch improves generation speed in some cases by avoiding pretty-printing overhead for non-failing examples.

6.108.5

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

This patch fixes a rare internal error when using :func:`~hypothesis.strategies.integers` with a high number of examples and certain ``{min, max}_value`` parameters (:pull:`4059`).

6.108.4

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

This patch addresses the issue of hypothesis potentially accessing
mocked ``time.perf_counter`` during test execution (:issue:`4051`).

6.108.3

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

Minor internal-only cleanups to some error-handling and reporting code.

6.108.2

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

This patch disables :func:`hypothesis.target` on alternative
backends where it would not work.

6.108.1

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

This patch updates our vendored `list of top-level domains <https://www.iana.org/domains/root/db>`__,
which is used by the provisional :func:`~hypothesis.provisional.domains` strategy.

6.108.0

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

This patch changes most Flaky errors to use an ExceptionGroup, which
makes the representation of these errors easier to understand.

6.107.0

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

The ``alphabet=`` argument to :func:`~hypothesis.strategies.from_regex`
now accepts unions of :func:`~hypothesis.strategies.characters` and
:func:`~hypothesis.strategies.sampled_from` strategies, in addition to
accepting each individually.

This patch also fixes a bug where ``text(...).filter(re.compile(...).match)``
could generate non-matching instances if the regex pattern contained ``|``
(:issue:`4008`).

6.106.1

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

This patch improves our pretty-printer (:issue:`4037`).

It also fixes the codemod for ``HealthCheck.all()`` from
:ref:`version 6.72 <v6.72.0>`, which was instead trying to
fix ``Healthcheck.all()`` - note the lower-case ``c``!
Since our tests had the same typo, it all looked good...
until :issue:`4030`.

6.106.0

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

This release improves support for unions of :pypi:`numpy` dtypes such as
``np.float64 | np.complex128`` in :func:`~hypothesis.strategies.from_type`
and :func:`~hypothesis.extra.numpy.arrays` (:issue:`4041`).

6.105.2

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

This patch improves the reporting of certain flaky errors.

6.105.1

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

This patch iterates on our experimental support for alternative backends (:ref:`alternative-backends`). See :pull:`4029` for details.

6.105.0

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

This release improves support for Django 5.0, and drops support for end-of-life Django versions (< 4.2).

Thanks to Joshua Munn for this contribution.

6.104.4

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

Clean up internal cache implementation.

6.104.3

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

This patch updates our autoformatting tools, improving our code style without any API changes.

6.104.2

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

This patch fixes an issue when realizing symbolics with our experimental :obj:`~hypothesis.settings.backend` setting.

6.104.1

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

Improves internal test coverage.

6.104.0

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

This release adds strategies for Django's ``ModelChoiceField`` and
``ModelMultipleChoiceField`` (:issue:`4010`).

Thanks to Joshua Munn for this contribution.

6.103.5

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

Fixes and reinstates full coverage of internal tests, which was accidentally
disabled in :pull:`3935`.

Closes :issue:`4003`.

6.103.4

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

This release prevents a race condition inside internal cache implementation.

6.103.3

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

This patch updates our vendored `list of top-level domains <https://www.iana.org/domains/root/db>`__,
which is used by the provisional :func:`~hypothesis.provisional.domains` strategy.

6.103.2

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

This patch improves our deduplication tracking across all strategies (:pull:`4007`). Hypothesis is now less likely to generate the same input twice.

6.103.1

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

Account for time spent in garbage collection during tests, to avoid
flaky ``DeadlineExceeded`` errors as seen in :issue:`3975`.

Also fixes overcounting of stateful run times,
a minor observability bug dating to :ref:`version 6.98.9 <v6.98.9>`
(:pull:`3890`).

6.103.0

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

This release migrates the shrinker to our new internal representation, called the IR layer (:pull:`3962`). This improves the shrinker's performance in the majority of cases. For example, on the Hypothesis test suite, shrinking is a median of 1.38x faster.

It is possible this release regresses performance while shrinking certain strategies. If you encounter strategies which reliably shrink more slowly than they used to (or shrink slowly at all), please open an issue!

You can read more about the IR layer at :issue:`3921`.

6.102.6

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

This patch fixes one of our shrinking passes getting into a rare ``O(n)`` case instead of ``O(log(n))``.

6.102.5

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

This patch fixes some introspection errors new in Python 3.11.9 and
3.13.0b1, for the Ghostwriter and :func:`~hypothesis.strategies.from_type`.

6.102.4

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

Internal developer documentation, no user-visible changes.

6.102.3

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

This patch improves our shrinking of unique collections, such as  :func:`~hypothesis.strategies.dictionaries`,
:func:`~hypothesis.strategies.sets`, and :func:`~hypothesis.strategies.lists` with ``unique=True``.

6.102.2

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

This patch fixes a rare internal error when generating very large elements from strategies (:issue:`3874`).

6.102.1

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

This patch fixes an overly strict internal type assertion.

6.102.0

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

This release improves our support for the :pypi:`annotated-types` iterable
``GroupedMetadata`` protocol.  In order to treat the elements "as if they
had been unpacked", if one such element is a :class:`~hypothesis.strategies.SearchStrategy`
we now resolve to that strategy.  Previously, we treated this as an unknown
filter predicate.

We expect this to be useful for libraries implementing custom metadata -
instead of requiring downstream integration, they can implement the protocol
and yield a lazily-created strategy.  Doing so only if Hypothesis is in
:obj:`sys.modules` gives powerful integration with no runtime overhead
or extra dependencies.

6.101.0

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

The :func:`~hypothesis.extra.django.from_model` function currently
tries to create a strategy for :obj:`~django:django.db.models.AutoField`
fields if they don't have :attr:`~django:django.db.models.Field.auto_created`
set to `True`.  The docs say it's supposed to skip all
:obj:`~django:django.db.models.AutoField` fields, so this patch updates
the code to do what the docs say (:issue:`3978`).

6.100.8

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

This patch adds some internal type annotations (:issue:`3074`).
Thanks to Andrew Sansom for his contribution!

6.100.7

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

This patch fixes a rare internal error when using :func:`~hypothesis.strategies.integers` with a high ``max_examples`` setting (:issue:`3974`).

6.100.6

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

This patch improves our internal caching logic. We don't expect it to result in any performance improvements (yet!).

6.100.5

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

This patch turns off a check in :func:`~hypothesis.register_random` for possibly
unreferenced RNG instances on the free-threaded build of CPython 3.13 because
this check has a much higher false positive rate in the free-threaded build
(:issue:`3965`).

Thanks to Nathan Goldbaum for this patch.

6.100.4

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

This patch turns off a warning for functions decorated with
:func:`typing.overload` and then :func:`~hypothesis.strategies.composite`,
although only in that order (:issue:`3970`).

6.100.3

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

This patch fixes a significant slowdown when using the :func:`~hypothesis.stateful.precondition` decorator in some cases, due to expensive repr formatting internally (:issue:`3963`).

6.100.2

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

Explicitly cast :obj:`numpy.finfo.smallest_normal` to builtin `float` in
preparation for the :pypi:`numpy==2.0 <numpy>` release (:issue:`3950`)

6.100.1

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

This patch improve a rare error message for flaky tests (:issue:`3940`).

6.100.0

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

The :func:`~hypothesis.extra.numpy.from_dtype` function no longer generates
``NaT`` ("not-a-time") values for the ``datetime64`` or ``timedelta64`` dtypes
if passed ``allow_nan=False`` (:issue:`3943`).

6.99.13

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

This patch includes the :obj:`~hypothesis.settings.backend` setting in the
``how_generated`` field of our :doc:`observability output <observability>`.

6.99.12

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

If you were running Python 3.13 (currently in alpha) with :pypi:`pytest-xdist`
and then attempted to pretty-print a ``lambda`` functions which was created
using the :func:`eval` builtin, it would have raised an AssertionError.
Now you'll get ``"lambda ...: <unknown>"``, as expected.

6.99.11

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

This release improves an internal invariant.

6.99.10

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

This patch fixes Hypothesis sometimes raising a ``Flaky`` error when generating collections of unique floats containing ``nan``. See :issue:`3926` for more details.

6.99.9

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

This patch continues our work on refactoring the shrinker (:issue:`3921`).

6.99.8

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

This patch continues our work on refactoring shrinker internals (:issue:`3921`).

6.99.7

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

This release resolves :py:exc:`PermissionError` that come from
creating databases on inaccessible paths.

6.99.6

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

This patch starts work on refactoring our shrinker internals. There is no user-visible change.

6.99.5

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

This patch fixes a longstanding performance problem in stateful testing (:issue:`3618`),
where state machines which generated a substantial amount of input for each step would
hit the maximum amount of entropy and then fail with an ``Unsatisfiable`` error.

We now stop taking additional steps when we're approaching the entropy limit,
which neatly resolves the problem without touching unaffected tests.

6.99.4

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

Fix regression caused by using :pep:`696` default in TypeVar with Python 3.13.0a3.

6.99.3

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

This patch further improves the type annotations in :mod:`hypothesis.extra.numpy`.

6.99.2

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

Simplify the type annotation of :func:`~hypothesis.extra.pandas.column` and
:func:`~hypothesis.extra.pandas.columns` by using :pep:`696` to avoid overloading.

6.99.1

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

This patch implements type annotations for :func:`~hypothesis.extra.pandas.column`.

6.99.0

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

This release adds the **experimental and unstable** :obj:`~hypothesis.settings.backend`
setting.  See :ref:`alternative-backends` for details.

6.98.18

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

This patch fixes :issue:`3900`, a performance regression for
:func:`~hypothesis.extra.numpy.arrays` due to the interaction of
:ref:`v6.98.12` and :ref:`v6.97.1`.

6.98.17

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

This patch improves the type annotations in :mod:`hypothesis.extra.numpy`,
which makes inferred types more precise for both :pypi:`mypy` and
:pypi:`pyright`, and fixes some strict-mode errors on the latter.

Thanks to Jonathan Plasse for reporting and fixing this in :pull:`3889`!

6.98.16

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

This patch paves the way for future shrinker improvements. There is no user-visible change.

6.98.15

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

This release adds support for the Array API's `2023.12 release
<https://data-apis.org/array-api/2023.12/>`_ via the ``api_version`` argument in
:func:`~hypothesis.extra.array_api.make_strategies_namespace`. The API additions
and modifications in the ``2023.12`` spec do not necessitate any changes in the
Hypothesis strategies, hence there is no distinction between a ``2022.12`` and
``2023.12`` strategies namespace.

6.98.14

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

This patch adjusts the printing of bundle values to correspond
with their names when using stateful testing.

6.98.13

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

This patch implements filter-rewriting for :func:`~hypothesis.strategies.text`
and :func:`~hypothesis.strategies.binary` with the :meth:`~re.Pattern.search`,
:meth:`~re.Pattern.match`, or :meth:`~re.Pattern.fullmatch` method of a
:func:`re.compile`\ d regex.

6.98.12

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

This patch implements filter-rewriting for most length filters on some
additional collection types (:issue:`3795`), and fixes several latent
bugs where unsatisfiable or partially-infeasible rewrites could trigger
internal errors.

6.98.11

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

This patch makes stateful testing somewhat less likely to get stuck
when there are only a few possible rules.

6.98.10

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

This patch :pep:`adds a note <678>` to errors which occur while drawing from
a strategy, to make it easier to tell why your test failed in such cases.

6.98.9

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

This patch ensures that :doc:`observability <observability>` outputs include
an informative repr for :class:`~hypothesis.stateful.RuleBasedStateMachine`
stateful tests, along with more detailed timing information.

6.98.8

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

This patch improves :doc:`the Ghostwriter <ghostwriter>` for binary operators.

6.98.7

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

This patch improves import-detection in :doc:`the Ghostwriter <ghostwriter>`
(:issue:`3884`), particularly for :func:`~hypothesis.strategies.from_type`
and strategies from ``hypothesis.extra.*``.

6.98.6

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

This patch clarifies the documentation on stateful testing (:issue:`3511`).

6.98.5

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

This patch improves argument-to-json conversion for :doc:`observability <observability>`
output.  Checking for a ``.to_json()`` method on the object *before* a few other
options like dataclass support allows better user control of the process (:issue:`3880`).

6.98.4

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

This patch updates our vendored `list of top-level domains <https://www.iana.org/domains/root/db>`__,
which is used by the provisional :func:`~hypothesis.provisional.domains` strategy.

6.98.3

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

This patch fixes an error when generating :doc:`observability <observability>` reports involving large (``n > 1e308``) integers.

6.98.2

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

This patch refactors some internals. There is no user-visible change.

6.98.1

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

This release improves our distribution of generated values for all strategies, by doing a better job of tracking which values we have generated before and avoiding generating them again.

For example, ``st.lists(st.integers())`` previously generated ~5 each of ``[]`` ``[0]`` in 100 examples. In this release, each of ``[]`` and ``[0]`` are generated ~1-2 times each.

6.98.0

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

This release deprecates use of the global random number generator while drawing
from a strategy, because this makes test cases less diverse and prevents us
from reporting minimal counterexamples (:issue:`3810`).

If you see this new warning, you can get a quick fix by using
:func:`~hypothesis.strategies.randoms`; or use more idiomatic strategies
:func:`~hypothesis.strategies.sampled_from`, :func:`~hypothesis.strategies.floats`,
:func:`~hypothesis.strategies.integers`, and so on.

Note that the same problem applies to e.g. ``numpy.random``, but
for performance reasons we only check the stdlib :mod:`random` module -
ignoring even other sources passed to :func:`~hypothesis.register_random`.

6.97.6

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

This patch updates our vendored `list of top-level domains <https://www.iana.org/domains/root/db>`__,
which is used by the provisional :func:`~hypothesis.provisional.domains` strategy.

6.97.5

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

This patch adds some :doc:`observability information <observability>`
about how many times predicates in :func:`~hypothesis.assume` or
:func:`~hypothesis.stateful.precondition` were satisfied, so that
downstream tools can warn you if some were *never* satisfied by
any test case.

6.97.4

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

This patch improves formatting and adds some cross-references to our docs.

6.97.3

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

Internal test refactoring.

6.97.2

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

This patch slightly changes how we replay examples from
:doc:`the database <database>`: if the behavior of the saved example has
changed, we now keep running the test case instead of aborting at the size
of the saved example.  While we know it's not the *same* example, we might
as well continue running the test!

Because we now finish running a few more examples for affected tests, this
might be a slight slowdown - but correspondingly more likely to find a bug.

We've also applied similar tricks to the :ref:`target phase <phases>`, where
they are a pure performance improvement for affected tests.

6.97.1

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

Improves the performance of the :func:`~hypothesis.extra.numpy.arrays`
strategy when generating unique values.

6.97.0

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

Changes the distribution of :func:`~hypothesis.strategies.sampled_from` when
sampling from a :class:`~python:enum.Flag`. Previously, no-flags-set values would
never be generated, and all-flags-set values would be unlikely for large enums.
With this change, the distribution is more uniform in the number of flags set.

6.96.4

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

This patch slightly refactors some internals. There is no user-visible change.

6.96.3

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

This patch fixes a spurious warning about slow imports when ``HYPOTHESIS_EXPERIMENTAL_OBSERVABILITY`` was set.

6.96.2

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

This patch refactors some more internals, continuing our work on supporting alternative backends (:issue:`3086`). There is no user-visible change.

6.96.1

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

Fix a spurious warning seen when running pytest's test
suite, caused by never realizing we got out of
initialization due to imbalanced hook calls.

6.96.0

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

Warns when constructing a `repr` that is overly long. This can
happen by accident if stringifying arbitrary strategies, and
is expensive in time and memory. The associated deferring of
these long strings in :func:`~hypothesis.strategies.sampled_from`
should also lead to improved performance.

6.95.0

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

This release adds the ability to pass any object to :func:`~hypothesis.note`, instead of just strings. The pretty-printed representation of the object will be used.

See also :issue:`3843`.

6.94.0

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

This release avoids creating a ``.hypothesis`` directory when using
:func:`~hypothesis.strategies.register_type_strategy` (:issue:`3836`),
and adds warnings for plugins which do so by other means or have
other unintended side-effects.

6.93.2

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

This patch improves :doc:`observability <observability>` reports by moving
timing information from ``metadata`` to a new ``timing`` key, and supporting
conversion of additional argument types to json rather than string reprs
via a ``.to_json()`` method (including e.g. Pandas dataframes).

Additionally, the :obj:`~hypothesis.HealthCheck.too_slow` health check will
now report *which* strategies were slow, e.g. for strategies a, b, c, ...::

     count | fraction |    slowest draws (seconds)
 a |    3  |     65%  |      --      --      --   0.357,  2.000
 b |    8  |     16%  |   0.100,  0.100,  0.100,  0.111,  0.123
 c |    3  |      8%  |      --      --   0.030,  0.050,  0.200
 (skipped 2 rows of fast draws)

6.93.1

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

This patch refactors some internals, continuing our work on supporting alternative backends
(:issue:`3086`). There is no user-visible change.

6.93.0

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

The :func:`~hypothesis.extra.lark.from_lark` strategy now accepts an ``alphabet=``
argument, which is passed through to :func:`~hypothesis.strategies.from_regex`,
so that you can e.g. constrain the generated strings to a particular codec.

In support of this feature, :func:`~hypothesis.strategies.from_regex` will avoid
generating optional parts which do not fit the alphabet.  For example,
``from_regex(r"abc|def", alphabet="abcd")`` was previously an error, and will now
generate only ``'abc'``.  Cases where there are no valid strings remain an error.

6.92.9

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

This patch refactors some internals, continuing our work on supporting alternative backends (:issue:`3086`). There is no user-visible change.

6.92.8

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

This patch adds a :ref:`test statistics <statistics>` event when a generated example is rejected via :func:`assume <hypothesis.assume>`.

This may also help with distinguishing ``gave_up`` examples in :doc:`observability <observability>` (:issue:`3827`).

6.92.7

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

This introduces the rewriting of length filters on some collection strategies (:issue:`3791`).

Thanks to Reagan Lee for implementing this feature!

6.92.6

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

If a test uses :func:`~hypothesis.strategies.sampled_from` on a sequence of
strategies, and raises a ``TypeError``, we now :pep:`add a note <678>` asking
whether you meant to use :func:`~hypothesis.strategies.one_of`.

Thanks to Vince Reuter for suggesting and implementing this hint!

6.92.5

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

This patch registers explicit strategies for a handful of builtin types,
motivated by improved introspection in PyPy 7.3.14 triggering existing
internal warnings.
Thanks to Carl Friedrich Bolz-Tereick for helping us work out what changed!

6.92.4

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

This patch fixes an error when writing :doc:`observability <observability>` reports without a pre-existing ``.hypothesis`` directory.

6.92.3

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

This patch adds a new environment variable ``HYPOTHESIS_EXPERIMENTAL_OBSERVABILITY_NOCOVER``,
which turns on :doc:`observability <observability>` data collection without collecting
code coverage data, which may be faster on Python 3.11 and earlier.

Thanks to Harrison Goldstein for reporting and fixing :issue:`3821`.

6.92.2

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

This patch updates our vendored `list of top-level domains <https://www.iana.org/domains/root/db>`__,
which is used by the provisional :func:`~hypothesis.provisional.domains` strategy.
