As formerly announced, see Announcements, we are going to upgrade the Python version from 3.9 to 3.13 on November 5, 2025.
Now you have the opportunity to test your affected pipelines with the new Python version before the actual upgrade and verify if the output is as expected.
To do that, follow these steps:
- 1. Go to your pipeline of interest and stop it if running.
- 2. In the App Settings tab, go to the new field called Pipeline Image Version.
- 3. Use the drop down list to switch to the new version Python 3.13.
- 4. Click the Save button to save the changes.
- 5. Run the pipeline again and a few reprocessing jobs if needed.
- 6. You may also check the App Console tab for further information.
- 7. Verify the output of the processing.
- 8. If needed, revert back to the Default version, again from the Pipeline Image Version field.
Please, be aware that after the actual upgrade on November 5, the default version will be changed to Python 3.13, but the older version 3.9 will still be available in this drop-down list for a grace period of one month. After that, version 3.9 will no longer be available.
