I have tagged v1.1.0. People who want to apply it can simply run copier -f update && pre-commit run -a. I'll deploy to all repos as soon as I can.
Note this release includes the move from travis to gha for the pre-commit step.

Do you think that it would be a good idea to add a workflow that, when doing a release, pushes it to all repos in supported branches (13.0 and 14.0 ATM)?

[sbidoul]

Sure an automation is needed, trust me it's not particularly fun to run it manually :). Making it robust is not entirely trivial. I'm polishing the script a little bit each time I run it. Unless something already cooked exists that I don't know?

Nope, but I could draft it to let you put your script logic over it.

@sbidoul Thanks, if repo maintainers are informed, I think they can take this in their hands.

[yajo]

@dreispt IMHO automation is a better option.

Well... maintainers must be informed, for sure; but I think it'll be more comfortable to fix the few problems that might happen than to keep track of the template and do manual updates every now and then.
