Which commit changes the caret to dash?

[tisonkun]

I tried to bump from 0.11 to 0.12. It seems a "breaking change" undocumented: the caret ^ was changed to dash -. May I ask which commit changes it?

Seems I should use AnnotationKind::Primary rather than AnnotationKind::Context. But the document is vague that I don't know which one should be used.

From the migration guide

• Instead of creating an Annotation from a Level, create them from an AnnotationKind
  • AnnotationKind::Primary will automatically match the Level of the Group
  • All others existing annotations should likely be AnnotationKind::Context

From the docs

Primary

For showing the source that the Group’s Title references

Context

Additional context to better understand the Primary Annotation

But the document is vague that I don't know which one should be used.

To me, the above docs are clear but I also wrote them. Is there any additional flavor to what you see as vague about them that could help me see them in a new light so I can consider how we should change them?
