@mat-hek I guess it should be done before v1.2.0, am I right?

[mat-hek]

It's an internal thing, so I think it doesn't matter. If we want to make it public, it can be as well in 1.2.1

[FelonEkonom]

It has been added to CallbackContexts in PR with telemetry, so it is a part of public API now and we can still change the name of it until v1.2.0, at least in callback contexts

[mat-hek]

Then yes, we need to change it before the release
