This release includes support for setting global application tags which will help Datadog better correlate your Python application traces and logs with other services in your infrastructure.
By providing the following settings, `ddtrace` will tag your application's traces and logs appropriately:
- `DD_ENV` environment variable or `ddtrace.config.env`: the environment in which your application is running. eg: `prod`, `staging`.
- `DD_VERSION` environment variable or `ddtrace.config.version`: the version of your application. eg: `1.2.3`, `6c44da20`, `2020.02.13`
- `DD_SERVICE` environment variable or `ddtrace.config.service`: the service which your application represents.
In you are using our logging integration manually, please update your formatter to also include the `dd.env`, `dd.service` and `dd.version` attributes as well. See our docs on [Logs Injection](http://pypi.datadoghq.com/trace/docs/advanced_usage.html?highlight=injection#logs-injection) for more details.
Profiling
If you are using the profiler, please note that `ddtrace.profile` has been renamed to `ddtrace.profiling`.
