This release of the Python agent includes a bug fix for tornado and support for recording deployment markers in the EU region as well as specifying a deploy timestamp.
Added timestamp and EU region support for recording deployment markers
When using the newrelic-admin record-deploy script an optional timestamp can be provided to specify when the deployment marker should be created. Furthermore support for accounts in the EU region have been added in this release.
Fixed a crash in tornado versions >= 6.1
Tornado 6.1 internals changed in a way that may have caused the agent's built-in instrumentation to fail. The instrumentation has been updated to alleviate this issue.
