Version 0.12.0

[dlech]

Added

• Added mtu_size property for clients.
• Added WinRT backend.
• Added BleakScanner.discovered_devices property.
• Added an event to await when stopping scanners in WinRT and pythonnet backends. Fixes AttributeError in WinRT scanner _stopped_handler() callback #556.
• Added BleakScanner.find_device_by_filter static method.
• Added scanner_byname.py example.
• Added optional command line argument to specify device to all applicable examples.

Changed

• Added Programming Language :: Python :: 3.9 classifier in setup.py.
• Deprecated BleakScanner.get_discovered_devices() async method.
• Added capability to handle async functions as detection callbacks in BleakScanner.
• Added error description in addition to error name when BleakDBusError is converted to string.
• Change typing of data parameter in write methods to Union[bytes, bytearray, memoryview].
• Improved type hints in CoreBluetooth backend.
• Use delegate callbacks for get_rssi() on CoreBluetooth backend.
• Use @objc.python_method where possible in PeripheralDelegate class.
• Using ObjC key-value observer to wait for BleakScanner.start() and stop()
  in CoreBluetooth backend.

Fixed

• Fixed KeyError when trying to connect to BLEDevice from advertising
  data callback on macOS. Fixes Device returned by detection callback is not properly initialized on corebluetooth #448.
• Handling of undetected devices in connect_by_bledevice.py example. Fixes Code working on Linux but not on Windows #487.
• Added Optional typehint for BleakScanner.find_device_by_address.
• Fixed linux_autodoc_mock_import in docs/conf.py.
• Minor fix for disconnection event handling in BlueZ backend. Fixes BlueZDBus: AttributeError in task callback #491.
• Corrections for the Philips Hue lamp example. Merged Correct and improve Philips Hue example #505.
• Fixed BleakClientBlueZDBus.pair() method always returning True. Fixes BlueZ backend always thinks device is paired? #503.
• Fixed waiting for notification start/stop to complete in CoreBluetooth backend.
• Fixed write without response on BlueZ < 5.51.
• Fixed error propagation for CoreBluetooth events.
• Fixed failed import on CI server when BlueZ is not installed.
• Fixed notification value should be bytearray on CoreBluetooth. Fixes CoreBluetooth: Callback gets _NSInlineData, not bytearray, causing methods to fail #560.
• Fixed crash when cancelling connection when Python runtime shuts down on
  CoreBluetooth backend. Fixes Crash on mac after timeout connecting to device #538.
• Fixed connecting to multiple devices using a single BleakScanner on
  CoreBluetooth backend.
• Fixed deadlock in CoreBluetooth backend when device disconnects while
  callbacks are pending. Fixes Program disconnects before connection established. Locks up Bleak #535.
• Fixed deadlock when using more than one service, characteristic or descriptor
  with the same UUID on CoreBluetooth backend.
• Fixed exception raised when calling BleakScanner.stop() when already
  stopped in CoreBluetooth backend.
