BREAKING Version 4 of the agent implements a new wire protocol for communicating with
the APM Server. This format is only supported in APM Server 6.5+.

Further breaking changes:

• the undocumented AsyncioHTTPTransport has been removed.
• the flush_interval and max_queue_size settings have been removed.
• new settings introduced: api_request_time and api_request_size.
• Some settings now require a unit for duration or size. See documentation on
  configuration for more information.
• The option to provide a custom date for exceptions and messages has been removed.

Other changes:

• on Python 3.7, use contextvars instead of threadlocals for storing
  current transaction and span. This is a necessary precursor for full asyncio support. (#291)

• fixed an issue when logging messages that are not strings (#295, #312)
• backported some documentation fixes
