  • The app_name setting has been renamed to service_name. The name of the analogous environment variable changed from ELASTIC_APM_APP_NAME to ELASTIC_APM_SERVICE_NAME.
  • app_name arguments to API calls in the whole code base changed to service_name.
  • The app_version setting has been renamed to service_version. The name of the analogous environment variable changed from ELASTIC_APM_APP_VERSION to ELASTIC_APM_SERVICE_VERSION.
  • context.request.url.raw has been renamed to context.request.url.full (#121)

• BREAKING: include_patterns and exclude_patterns now use shell globs instead of regular expressions, and are matched against the full path file path of the module, not against the module name (#137)

• BREAKING: renamed several configuration options to align better with other language agents (#145):

  • disable_instrumentation became instrument and inverted its meaning
  • max_event_queue_length became max_queue_size
  • timeout became server_timeout

• added a background thread to process the transactions queue every 60 seconds (configurable) (#68)
• adapted trace context for SQL traces to new API (#77)
• ensured that transaction data is also passed through processors (#84)
• added uninstrument function to reverse instrumentation,
  and exposed both instrument and uninstrument as public API in the elasticapm namespace (#90)
• added normalization of HTTP status codes into classes for the transaction.result field. A HTTP status of 200
  will be turned into HTTP 2xx. The unchanged status code is still available in context.response.status_code.
