Dynatrace extension framework upgrade notice

Starting with Dynatrace OneAgent and ActiveGate version 1.231, we are upgrading the Extension Framework (also referred to as the plugins framework) from Python 3.6 to 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.
Symptoms:
- No data is provided for affected metrics on dashboards, alerts, and custom device pages populated by the affected extension metrics.
- Extension logs display errors. Most often this will manifest itself as Python ModuleNotFoundError in the PluginAgent log.
- Sometimes the Python virtual machine crashes.
Impact: This issue affects only those extensions that use native libraries called from Python code distributed with the extension.

Chromium support for private Synthetic locations

Chromium 96 is now the latest supported version for Synthetic-enabled ActiveGate versions 1.231–1.233 for Ubuntu 18.04 and 20.04, Red Hat Enterprise Linux and CentOS 8, and bundled with the Windows ActiveGate installer. For more information, see Requirements for private Synthetic locations.

Chromium 96 is supported starting with Synthetic module version 1.231.45.20220111-140719. You will get Chromium version 96 automatically or these Linux-based operating systems if you've selected Enable Chromium Auto-update for your private locations. Otherwise, you need to update Chromium manually—see Manage private Synthetic locations. We recommend that you update Chromium to version 96, because it solves authentication issues caused by Chromium version 95.

Chromium development for Ubuntu 16.04 stopped at version 90.
An update for Chromium on Red Hat Enterprise and CentOS 7 is available with ActiveGate version 1.235. (Chromium development had previously stopped at version 90.)
