Legacy actions, and how to proceed?

[golles]

In 2024.12 Actions was renamed to (Legacy) iOS Actions (as in #3251)

I did hear/read something about this before, but what's next? What are we supposed to do now? I can't seem to find anything about that.
Eg. https://companion.home-assistant.io/docs/core/actions and the release notes don't mention anything about it.

I've got a few actions defined in Yaml that are used on a daily base, so I'd like to know what I should be doing to stop using legacy features.

Thanks!
