Friendly Reminder

This release still contains a variety of deprecation notices about defaults 
that can be set for a variety of options.
Please note that this is your last warning, and you should update your 
configuration if you do NOT want to use the new defaults.
See the arguments documentation page for all supported options, and pay 
attention to the warnings:

https://docs.pylonsproject.org/projects/waitress/en/stable/arguments.html

Without further ado, here’s a short list of great changes thanks to our 
contributors!

Bugfixes/Features
        • Fix a crash on startup when listening to multiple interfaces. See 
https://github.com/Pylons/waitress/pull/332
        • Waitress no longer attempts to guess at what the server_name should 
be for a listen socket, instead it always use a new adjustment/argument named 
server_name.
Please see the documentation for server_name 
inhttps://docs.pylonsproject.org/projects/waitress/en/latest/arguments.html and 
see https://github.com/Pylons/waitress/pull/329
        • Allow tasks to notice if the client disconnected.
This inserts a callable waitress.client_disconnected into the environment that 
allows the task to check if the client disconnected while waiting for the 
response at strategic points in the execution and to cancel the operation.
It requires setting the new adjustment channel_request_lookahead to a value 
larger than 0, which continues to read requests from a channel even if a 
request is already being processed on that channel, up to the given count, 
since a client disconnect is detected by reading from a readable socket and 
receiving an empty result.
See https://github.com/Pylons/waitress/pull/310
        • Drop Python 2.7 and 3.5 support
        • The server now issues warning output when it there are enough open 
connections (controlled by “connection_limit”), that it is no longer accepting 
new connections. This situation was previously difficult to diagnose. See 
https://github.com/Pylons/waitress/pull/322
