python 3.9 use old version of matplotlib and pyparser which leads to a lot of Deprecation Warning (due to CamelCase -> snake_case). To exclude them one by one is too much and i failed to remove them via pattern. Since it is only for old version I ignore all Depreciation warning for this particular version.

I have checked and python 3.9 reached end of life in October 2025.

I guess we have a strong case to remove it from the continuous integration unless it is still used in ESRF systems.

I think it is going to be (officially already but on practice not yet) deprecated along with Ubuntu 20.04 but it is still used but in just few places.

FYI Ubuntu 20.04 is python 3.8

As for the scheduled CI: note that we only have 2000 action minutes per month for the silx-kit organization.

For the Ewoks core projects we will have the scheduled CI on gitlab.

Should we then redo it for "weekly" instead of "daily"?
