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
