hello, maybe somebody have answer to this: Is it risky adding @Immutable to an existing data class because we start using it in Compose ?

[Stylianos Gakis]

What do you mean by “risky”?

[Tinh]

like on old usages will it cause crash or will it change their behavior somehow ?

[Stylianos Gakis]

What is “old usages” in this context?
If you are adding @Immutable to a class that is in fact @Immutable, aka doesn’t break the contract that it needs to follow to be described as immutable, then I don’t see a reason why adding it yourself would be problematic.
But I may be missing some context in what you mean with “old usages”.

Annotating with @Immutable should not break existing non-Compose usages, no. It's a contract between you and the Compose Compiler.
