- Update to 3.1.1
* Fix crashes on 32-bit PPC Linux. Note that there is no CI for this,
and support is best effort; there may be other issues lurking.
* Remove unnecessary logging sometimes during interpreter shutdown.
* Fix some crashes on 32-bit PPC MacOS. This is a very old platform,
and is only known to be tested on beta versions of an operating
system that was never released, using the GCC 14 only provided by
MacPorts; it may or may not work on the final MacOS X release that
supported 32-bit PowerPC. It has the known issue of leaking memory
when greenlets are used in multiple threads. Help debugging this
would be appreciated.
