[ANN] PyObjC 5.1.2

Hi,

I’ve pushed PyObjC 5.1.2 to PyPI. This release contains a number of bugfixes:

* #254: Fix compile error on macOS 10.9 or earlier

* #255: Calling completion handler failed due to incomplete runtime info

  PyObjC's metadata system didn't automaticly set the call signature
  for blocks passed into a method implemented in Python. This causes problems
  when the ObjC or Swift block does not have signature information in the
  ObjC/blocks runtime.

* Use MAP_JIT when allocating memory for the executable stubs for Python
  methods.

  With the "restricted" runtime you'll have to add the "com.apple.security.cs.allow-jit"
  entitlement to use this flag, in earlier versions you'd have to use
  a different entitlement: "com.apple.security.cs.allow-unsigned-executable-memory".

  The MAP_JIT flag is only used on macOS 10.14 or later.

* Ensure that PyObjC can be built using /usr/bin/python on macOS 10.14

  This failed due the problems with header files in the SDK included with Xcode 10.

Regards,

  Ronald
