Python 3.10 end of support (Oct 2026) - What Extensions & OneAgents?

jmccullough3 — Thu, 23 Apr 2026 12:34:42 GMT

"Python 3.10 will no longer be supported after October 2026. To maintain Python extension support, OneAgents and ActiveGates starting from version 1.333 will include a new Python 3.14 runtime to be used for extensions."

1. Can you tell us the list of extensions and versions which will be impacted? We have hubdreds of customers and many, many extensions deployed across them. We want to target those which will be impacted first and then remaining customers later.

2. If extensions are not updated to more current versions will there still be an impact in Oct 2026?

3. What will be the impact to the ActiveGate if they are not updated?

4. What will be the impact to the OneAgents if they are not updated? We have over 50k OneAgents deployed and it might not be feasible to ensure they are all updated to v1.333

Hi,

1. Almost all Python extensions are impacted by this. There are a handful older ones that had no Python version dependency, but the majority are affected.

2. Once you update to the OneAgent/ActiveGate version which is released in October, all extensions not built for 3.14 will stop working.

3+4. If you don't update the ActiveGates/OneAgents the existing extensions will keep running. However, you will be running an unsupported Python version on your infrastructure, which we recommend against for security reasons. We are also starting to ship extensions with a minimum version of 1.333, which won't work on older OneAgents/ActiveGates. If you don't update your ActiveGates/OneAgents, you will not get all the new features we are shipping, such as Entities on Grail.

There are hundreds of extensions. I have no ideas what extensions we are talking about when you say "Almost all Python extensions are impacted by this". IS there an actual list of extensions which run python?

There is not a list of extensions that use Python, but within the product you can see the affected extensions in the extension app. I've forwarded this thread to the relevant product manager who is running the framework upgrade.

Please also check out the doc page about this topic:

https://docs.dynatrace.com/docs/shortlink/python-extension-runtime-update#validate-the-migration

We will add a link to it in the banner in the APP as well soon.

While we call it as Python 3.10 being unsupported based on our definition, they state it as end of life: https://devguide.python.org/versions/

Hi,

Thank you! I was not aware of that documentation!
