Version 1.5
-----------
Released 2022-07-17
- Support Python >= 3.7 and PyPy. Python 2, Python < 3.7, and Jython
may continue to work, but the next release will make incompatible
changes.
Version 1.4
-----------
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.
Version 1.3
-----------
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.
Version 1.2
-----------
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.
Version 1.1
-----------
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.
Version 0.9
-----------
Released 2010-02-26
- Added ``Signal.temporarily_connected_to`` context manager.
- Docs! Sphinx docs, project web site.
Version 0.8
-----------
Released 2010-02-14
- Initial release.
