Log message:
py-pyobjc: updated to 6.2.1

Version 6.2.1
* Ensure package ‘pyobjc’ won’t try to build the PubSub bindings on macOS 10.15
* Minor tweaks to build and pass tests on macOS 10.14 with the latest Xcode that \ 
can be installed on that version of macOS.
* Fix SystemError in block edge case
* PyObjC raised a SystemError when converting a callable into an ObjC block when \ 
the callable is a bound method without positional arguments.
* Fix crash on catalina caused by writing to read-only memory.
* Make sure the SDK detection works when the version is not in the SDK name
* There were no SDK updates in Xcode 11.5 and Xcode 11.6 (beta)

Log message:
py-pyobjc: updated to 6.2

Version 6.2

The project has moved from Bitbucket to Github

Remove most remnants of Python 2 support

Clean up code quality issues found using flake8

Add pre-commit hook to run black on all Python code.

Fix protocol conformance testing when explicitly implementing a protocol

Before this bugfix a class explicitly conforming to a protocol could not \ 
implement any method that wasn’t declared in the protocol, the bridge would \ 
erroneously raise an exception when checking the additional method.

Issue reported by Georg Seifert.

Fix Python 3 issues in PyObjCTools.Conversion

Reported by vinolin asokan.

PyObjCTools.Conversio.propertyListFromPythonCollection didn’t
recursively convert members of lists and tuples.

PyObjCTools.Conversio.propertyListFromPythonCollection and \ 
PyObjCTools.Conversio.pythonCollectionFromPropertyList now support sets.

Update metadata for Xcode 11.4 (beta 2)

Added bindings for framework AutomaticAssessmentConfiguration.framework \ 
introduced in macOS 10.15.4

In some cases the compiler uses the type encoding “^{NSObject=#}” instead of \ 
“@”.

Reported by Georg Seifert.

Added bindings for the Metal framework (new in macOS 10.11)

Most framework bindings now use the limited ABI for the included C extensions, \ 
reducing the number of wheels that are needed. The exception are the bindings \ 
for Cocoa, Quartz and libdispatch, those use functionality not available in the \ 
limited ABI.

The bridge itself (pyobjc-core) still uses the full CPython API.

The CoreAudio bindings also don’t use the limited ABI for now, those need more \ 
work to work with that ABI.

Log message:
py-pyobjc: updated to 6.1

Version 6.1
Updated for the macOS 10.15.1 SDK (Xcode 11.2)
Fix reference counting in -[OC_PythonData length], which resulted in use-after-free.
Fix problems found in pyobjc-core by the clang static analyser

Version 6.0.1
Remove debug print accidently left in production
Surpress “-Wunguarded-availability” warnings in the extension AppKit._inlines

Version 6.0
Removed Python 2 support from the C extension in pyobjc-core
Reformatted code in pyobjc-core:
- Use “black” for Python code
- Use “clang-format” for Objective-C code
Updated bindings for macOS 10.15 (Xcode 11.0)
The userspace driver frameworks introduced in macOS 10.15 (DriverKit and related \ 
frameworks) will not be exposed through PyObjC. Please let me know if you have a \ 
good use case for using these frameworks with Python.
Add new framework wrappers for all other new frameworks in macOS 10.15:

AuthenticationServices
CoreHaptics
CoreMotion
DeviceCheck
ExecutionPolicy
FileProvider
FileProviderUI
LinkPresentation
OSLog
PencilKit
PushKit
QuickLookThumbnailing
Speech
SoundAnalysis
SystemExtensions
Add new framework wrappers for a number of older frameworks:

MetalKit (new in macOS 10.11)
Fix crash when creating NSData objects on macOS 10.15

Log message:
py-pyobjc: updated to 5.2

Version 5.2
* Updated metadata for Xcode 10.2

* objc.registerStructAlias no longer emits a deprecation warning because it is \ 
still used by the framework wrappers.
  The function is still deprecated though, the deprecation will reappear once \ 
the metadata has been updatd.

* The core bridge now uses PyDict_GetItemWithError(), which may result in \ 
exceptions being raised that were previously swallowed.

* Partially switch to the new buffer API instead of the older Python 2 buffer API.
  The new implementation is more correct, but may keep Python objects alive \ 
longer than the previous implementation, and also affects buffer related \ 
functionality of Python objects. In particular, calling [someData bytes] on a \ 
Python object keeps the Py_buffer alive until the next flush of the \ 
autoreleasepool.

* Fix incorrect metadata for the callback argument to \ 
-[AVCaptureStillImageOutput \ 
captureStillImageAsynchronouslyFromConnection:completionHandler:].

* Add bindings to the “PrintCore” APIs from the ApplicationServices framework.
  Python 2: UserDict.UserDict instances are now bridged to instances of a \ 
subclass of NSDictionary.

Log message:
py-pyobjc: updated to 5.1.2

Version 5.1.2
Fix compile error on macOS 10.9 or earlier
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.

Version 5.1.1
Update metadata for Xcode 10.1

Version 5.1
Xcode 10 “GM” contains one difference from the last beta: the constant \ 
MLComputeUnitsCPUAndGPU in the CoreML bindings.
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
Import ABCs from collections.abc instead of collections because the latter is \ 
deprecated.
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.

Version 5.0
Version 5.0 of PyObjC primarily adds support for macOS 10.14 (mojave), and also \ 
adds support for a couple of older frameworks that weren’t supported before.

Log message:
py-pyobjc: updated to 4.2.2

Version 4.2.2:
Update metadata for Xcode 9.4
The binary release now includes wheels for both variants for the Python.org \ 
installer for python 3.6 and 3.7: 32- and 64-bit for macOS 10.6 or later, and \ 
64-bit only for macOS 10.9 or later.
Ensure the context manager for NSAnimationContext defined in \ 
PyObjCTools.AppCategories actually works.
Fix convenience wrappers for Foundation.NSCache.
Fix convenience wrappers for Foundation.NSHashTable.
