Hypothesis previously required attrs as a dependency. This release
removes that dependency, so that the only required dependency of
Hypothesis is sortedcontainers.

All attrs-specific features of Hypothesis, such as using "from_type()"
with attrs classes, will continue to behave as before.

Tweak how Hypothesis hides internal tracebacks to fix an error under
rare conditions (issue #3822).

This release adds support for "Fraction" objects as "min_value" and
"max_value" bounds in "decimals()", if they can be exactly represented
as decimals in the target precision (issue #4466).

Bounding "decimals()" with other values that cannot be exactly
represented is now deprecated; previously the bounds could be off by
one.

"from_type()" now correctly handles annotated-types annotations on
"typing.TypedDict" fields which are also marked as being "ReadOnly",
"Required", or "NotRequired" (issue #4474).

The extras for NumPy and pandas now support automatically inferring a
strategy for "dtype="O"". Previously, Hypothesis required an explicit
elements strategy to be passed, for example "nps.arrays("O",
shape=(1,), elements=st.just(object()))". Now, Hypothesis
automatically infers "elements=st.from_type(object)".

Thanks to Shaun Read for identifying and fixing this!

This patch fixes "binary_operation()" to include imports for
"hypothesis.extra.numpy" strategies such as "arrays()",
"scalar_dtypes()", and "array_shapes()" when ghostwriting tests for
functions with numpy array parameters (issue #4576).

time of each test case closer to when the test is executed.

Fix a recursion error when observability is enabled and a test
generates an object with a recursive reference, like "a = [];
a.append(a)".

Remove a case where Hypothesis would interact with the global
"random.Random" instance if Hypothesis internals were used directly.
