Is there a hook for a field?

[Alain]

Check this if some stumbles over the same point:

Hook 'page.update:after' new and old Page does not return in the exact same result even if they are unchanged

I solved it by a workaround. I had to do this to remove \n on the $newField: $newField = rtrim($newField, "\n"); I would define this as a Kirby Bug. Please correct me if I’m wrong.
