Auto merge of #13396 - epage:changelog, r=weihanglo

docs(changelog): Slight cleanup

### What does this PR try to resolve?

For strip, I felt the nuance of where this change applies isn't as obvious and might give people the wrong impression, so I tried to make that front and center.

For the panic, the fix was backported to 1.77 (#13393) which is when it got introduced (#13172).
