Hi,

I’ve pushed PyObjC 5.1 to PyPI. This is a minor feature release.  The most 
interesting change is that the Objective-C proxies for builtin Python types now 
support NSSecureCoding.


The full list of changes:

Xcode 10 “GM” contains one difference from the last beta: the constant 
MLComputeUnitsCPUAndGPU in the CoreML bindings.

#222: Add a proxy for C’s “FILE*” type on Python 3. This is not necessary on 
Python 2 because the default IO stack on Python 2 already uses FILE* internally.

This proxy type is very minimal and shouldn’t not be used for general I/O.

Bindings are up-to-date w.r.t. Xcode 10.1 (beta)

Updated the support code for framework wrappers to be able to emit deprecation 
warnings on the first import of a deprecated constants (functions and methods 
will only raise a deprecation warning when called).

This is just an infrastructure change, the actual framework bindings do not yet 
contain the information used to emit deprecation warnings.

Add metadata for deprecation warnings to the “Contacts” framework

#252: Import ABCs from collections.abc instead of collections because the 
latter is deprecated.

#180, #251: Instances of most builtin value types and sequences (int, float, 
str, unicode, tuple, list, set, frozenset and dict) can now be written to 
archives that require secureCoding.
