0.17.3 (5th July 2023)

• Support async cancellations, ensuring that the connection pool is left in a clean state when cancellations occur. (#726)
• The networking backend interface has been added to the public API. Some classes which were previously private implementation detail are now part of the top-level public API. (#699)
• Graceful handling of HTTP/2 GoAway frames, with requests being transparently retried on a new connection. (#730)
• Add exceptions when a synchronous trace callback is passed to an asynchronous request or an asynchronous trace callback is passed to a synchronous request. (#717)
