Dear all,

I'm pleased to announce that the Python client version 1.6.1 has been
released. Version 1.6.0 was also released but broke Python 2.7
support, which was not intended.

The 1.6.0 feature changes are:

- Callbacks can now be updated from within a callback.
- Big performance improvement when receiving large payloads,
particularly for SSL. Closes #571,
- Add basic MQTT v5 support to the subscribe and publish helper
functions. Closes #575.
- Changed default TLS version to 1.2 instead of 1.0.
- Remove _out_packet_mutex and _current_out_packet_mutex and convert
the _out_packet queue use to thread safe (simplifies the internals)
- Callbacks can now be applied to client instances using decorators.
- The `rc` parameter in the `on_disconnect` callback now has
meaningful values in the case of an error. Closes #441.
- Remove periodic retry checks for outgoing messages with QoS>0. This
means that outgoing messages will only be retried on the client
reconnecting to the server. They will *not* be retried when the client
is still connected.
- MQTTMessageInfo.wait_for_publish() and
MQTTMessageInfo.is_published() will now raise exceptions if called
when the publish call produced an error. Closes #550.
- Raise exceptions when attempting to set MQTT v5 properties to
forbidden values. Closes #586.
- PUBACK messages are now sent to the broker only after the on_message
callback has - Add timeout to
- Add timeout to MQTTMessageInfo:wait_for_publish().
- Removed ancient Mosquitto compatibility class.

And fixes:

- Fix incoming MQTT v5 messages with overall property length > 127
bytes being incorrectly decoded. Closes #541.
- Fix on_disconnect() sometimes calling the MQTT v3.x callback when it
should call the MQTT v5 callback. Closes #570.
- Fix connecting with MQTT v5 to a broker that doesn't support MQTT
v5. Closes #566.
- Fix exception on calling Client(client_id="", clean_session=False).
Closes #520.
- Experimental support for Websockets continuation frames. Closes
#500. Closes #89.
- `Properties.json()` now converts Correlation Data bytes() objects to
hex. Closes #555.
- Only use the internal sockpair wakeup when running with loop_start()
or loop(). This removes problems when running with an external event
- Drain all of sockpairR bytes to avoid unnecessary wakeups and
possible timeouts. Closes #563.


Fantastic work! Thanks!
