Gipc

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

This release adds support for gevent 23.9.1 and for Python 3.12.

Continuous integration changes:

- Cover CPython 3.12 (Linux, Windows, macOS).
- Switch from testing on macOS 10 to macOS 11.
- Do not test with Python 3.7 anymore.

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

This release adds support for gevent 22.12.2 and for Python 3.11.

Continuous integration changes:

- Cover CPython 3.11 (Linux, Windows, macOS).
- Cover PyPy 3.9.
- Do not test with Python 3.6 anymore.

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

This release adds support for gevent 21.12.0 and for Python 3.10.

Continuous integration changes:

- Cover CPython 3.10 (Linux, Windows, macOS)
- Cover PyPy 3.8 instead of PyPy 3.6 (Linux, macOS)

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

This release adds support for gevent 21.x and CPython 3.8+ on macOS (thanks to
Tyler Willey for crunching through this).

On macOS with CPython 3.8 and newer, gipc now supports the new default
``multiprocessing`` process invocation method which is based on ``spawn()``, similar
to ``CreateProcess()`` on win32. Depending on the needs of your application, you
may want to explore setting the process invocation method back to ``fork()`` via
``multiprocessing.set_start_method('fork')``.

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

This release adds support for gevent 21.x on Linux and Windows, tested with
CPython 3.6, 3.7, 3.8, and 3.9.

For macOS, this gipc release still does not support CPython 3.8 and newer.

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

This release

- adds support for gevent 1.5 on Linux, macOS, and Windows.

- adds CPython 3.8 support for Linux and Windows.

The combination of gevent 1.5.0 (and newer), CPython 3.8 and Darwin (macOS) is
not supported. Adding support is tracked in `issue 100 <https://github.com/jgehrcke/gipc/issues/100>`_.


Continuous integration changes:

- Moved from Travis CI (and AppVeyor) to GitHub Actions, in view of `sadness <https://news.ycombinator.com/item?id=18978251>`_
affecting so many open source projects.

- gevent 1.2.x, 1.3.x, 1.4.x are not covered anymore by CI (1.4.x still works, though).

- CPython 2.7 and PyPy 2.7 are not covered anymore (should still work with this release, though).

- Newer CPython and PyPy releases are covered by automatic testing now.

Note: the next version of gipc is likely to

- only support gevent 20.x and newer

- not support CPython 2.7 anymore

As these are significat compatibility changes, the next gipc release will most likely have version 2.0.
