OneAgent release notes version 1.229

Rollout starts November 22, 2021

With this release, the oldest supported OneAgent versions are:

Dynatrace extension framework upgrade notice

Starting with Dynatrace version 1.231, the Extension Framework (also referred to as the plugins framework) will start using Python 3.8. The Python 3.6 component will be replaced by Python 3.8.

Consequences: Some Dynatrace extensions running in your environment may stop working and require redeployment of a new version prepared for Python 3.8.

Impact: This issue will rarely happen. It affects only those extensions that use native libraries called from Python code distributed with the extension.

Symptoms: Metrics provided by affected extensions may stop working, such that no data is provided for affected metrics on dashboards, alerts, and custom device pages populated by the affected extension metrics. At the same time, extension logs will display errors.

We'll provide more details and a detailed procedure before the Dynatrace version 1.231 release.
