This is the Blinker 1.8.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes.

PyPI: https://pypi.org/project/blinker/1.8.2/
Changes: https://blinker.readthedocs.io/en/latest/#version-1-8-2

• Simplify type for _async_wrapper and _sync_wrapper arguments. #156

This is the Blinker 1.8.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes.

PyPI: https://pypi.org/project/blinker/1.8.1/
Changes: https://blinker.readthedocs.io/en/latest/#version-1-8-1

• Restore identity handling for str and int senders. #148
• Fix deprecated blinker.base.WeakNamespace import. #149
• Fix deprecated blinker.base.receiver_connected import. #153
• Use types from collections.abc instead of typing. #150
• Fully specify exported types as reported by pyright. #152

This is the Blinker 1.8.0 feature release, which may include new features, remove previously deprecated code, or add new deprecations. The 1.8.x line is now the supported fix branch, support has ended for the 1.7.x line. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

PyPI: https://pypi.org/project/blinker/1.8.0/
Changes: https://blinker.readthedocs.io/en/latest/#version-1-8-0

• Deprecate the __version__ attribute. Use feature detection, or importlib.metadata.version("blinker"), instead. #128
• Specify that the deprecated temporarily_connected_to will be removed in the next version.
• Show a deprecation warning for the deprecated global receiver_connected signal and specify that it will be removed in the next version.
• Show a deprecation warning for the deprecated WeakNamespace and specify that it will be removed in the next version.
• Greatly simplify how the library uses weakrefs. This is a significant change internally but should not affect any public API. #144
• Expose the namespace used by signal() as default_namespace. #145

Released 2023-11-01

• Fixed messages printed to standard error about unraisable exceptions during signal cleanup, typically during interpreter shutdown. 123

• Allow the Signal set_class to be customised, to allow calling of receivers in registration order. 116.

• Drop Python 3.7 and support Python 3.12. 126

Released 2023-09-23

• Fix SyncWrapperType and AsyncWrapperType 108

• Fixed issue where connected_to would not disconnect the receiver if an instance of BaseException was raised. 114

Released 2023-04-12

• Type annotations are not evaluated at runtime. typing-extensions is not a runtime dependency. 94

Released 2023-04-09

• Ensure that py.typed is present in the distributions (to enable other projects to use Blinker's typing).

• Require typing-extensions > 4.2 to ensure it includes ParamSpec. 90

Released 2023-04-02

• Add a muted context manager to temporarily turn off a signal. 84

• int instances with the same value will be treated as the same sender, the same as str instances. 83

• Add a send_async method to allow signals to send to coroutine receivers. 76

• Update and modernise the project structure to match that used by the Pallets projects. 77

• Add an initial set of type hints for the project.

Blinker has moved to Pallets-Eco, an organization for community maintenance of projects related to Pallets, Flask, etc. If you use Blinker and are interested in helping maintain the project, please join us in Discord Chat https://discord.gg/pallets.

This release fixes some compatibility with Python >= 3.7. Python < 3.7, including 2.7 and Jython, should still work for this release, but will no longer be supported in the next release.

The documentation has moved to Read the Docs https://blinker.readthedocs.io.

Released 2015-07-23

• Verified Python 3.4 support, no changes needed.

• Additional bookkeeping cleanup for non-ANY connections at disconnect time.

• Added Signal._cleanup_bookeeping() to prune stale bookkeeping on demand.

Released 2013-07-03

• The global signal stash behind signal() is now backed by a regular name-to-Signal dictionary. Previously, weak references were held in the mapping and ephermal usage in code like signal('foo').connect(...) could have surprising program behavior depending on import order of modules.

• Namespace is now built on a regular dict. Use WeakNamespace for the older, weak-referencing behavior.

• Signal.connect('text-sender') uses an alterate hashing strategy to avoid sharp edges in text identity.

Released 2011-10-26

• Added Signal.receiver_connected and Signal.receiver_disconnected per-Signal signals.

• Deprecated the global receiver_connected signal.

• Verified Python 3.2 support, no changes needed.

Released 2010-07-21

• Added @signal.connect_via(sender) decorator

• Added signal.connected_to shorthand name for the temporarily_connected_to context manager.

Released 2010-03-28

• Python 3.0 and 3.1 compatibility.

Released 2010-02-26

• Added Signal.temporarily_connected_to context manager.

• Docs! Sphinx docs, project web site.

Released 2010-02-14

• Initial release.

• Extracted from flatland.util.signals.

• Added Python 2.4 compatibility.

• Added nearly functional Python 3.1 compatibility. Everything except connecting to instance methods seems to work.
