Traction is designed with an API-first architecture layered on top of Hyperledger Aries Cloud Agent Python (ACA-Py) and streamlines the process of sending and receiving digital credentials for governments and organizations.
This release focuses on compatibility with the upcoming release of
Python 3.13. Most changes are related to the implementation of type
parameter defaults (PEP 696).
Thanks to all of the people who contributed patches, especially Alex
Waygood, who did most of the work adapting typing-extensions to the
CPython PEP 696 implementation.
There is a single change since 4.12.0rc1:
Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and
3.9 that meant that
isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a
different result in some situations depending on whether or not a profiling
function had been set using sys.setprofile. Patch by Alex Waygood.
Changes included in 4.12.0rc1:
Improve the implementation of type parameter defaults (PEP 696)
Backport the typing.NoDefault sentinel object from Python 3.13.
TypeVars, ParamSpecs and TypeVarTuples without default values now have
their __default__ attribute set to this sentinel value.
TypeVars, ParamSpecs and TypeVarTuples now have a has_default()
method, matching typing.TypeVar, typing.ParamSpec and
typing.TypeVarTuple on Python 3.13+.
TypeVars, ParamSpecs and TypeVarTuples with default=None passed to
their constructors now have their __default__ attribute set to None
at runtime rather than types.NoneType.
Fix most tests for TypeVar, ParamSpec and TypeVarTuple on Python
3.13.0b1 and newer.
Backport CPython PR #118774,
allowing type parameters without default values to follow those with
default values in some type parameter lists. Patch by Alex Waygood,
backporting a CPython PR by Jelle Zijlstra.
It is now disallowed to use a TypeVar with a default value after a
TypeVarTuple in a type parameter list. This matches the CPython
implementation of PEP 696 on Python 3.13+.
Fix bug in PEP-696 implementation where a default value for a ParamSpec
would be cast to a tuple if a list was provided.
Patch by Alex Waygood.
Fix Protocol tests on Python 3.13.0a6 and newer. 3.13.0a6 adds a new
__static_attributes__ attribute to all classes in Python,
which broke some assumptions made by the implementation of
typing_extensions.Protocol. Similarly, 3.13.0b1 adds the new
__firstlineno__ attribute to all classes.
Fix AttributeError when using typing_extensions.runtime_checkable
in combination with typing.Protocol on Python 3.12.2 or newer.
Patch by Alex Waygood.
At runtime, assert_never now includes the repr of the argument
This release is mostly the same as 4.12.0rc1 but fixes one more
longstanding bug.
Fix incorrect behaviour of typing_extensions.ParamSpec on Python 3.8 and
3.9 that meant that
isinstance(typing_extensions.ParamSpec("P"), typing.TypeVar) would have a
different result in some situations depending on whether or not a profiling
function had been set using sys.setprofile. Patch by Alex Waygood.
