Datadog has released version 7 of its Agent, which now exclusively supports the Python 3 runtime, marking a shift from previous versions that supported both Python 2 and 3, in line with Python 2's end of life in January 2020. The new release maintains all functionalities from Agent 6, and Datadog has tested over 850 integrations to ensure compatibility with Python 3. Users with custom checks written in Python 2 are provided with tools and documentation to facilitate migration, including an in-app Custom Check Compatibility tool and a detailed migration guide. Datadog Agent 6.16 allows users to test Python 3 compatibility by configuring the runtime version, ensuring a smooth transition before upgrading to Agent 7. The documentation also includes resources for using Containerized Agent images and libraries to aid in converting Python 2 code to Python 3, with a free 14-day trial available for new users.
