API Change Log or Release Notes placeholder?

I am reaching out to get inputs to maintain the API change log / release notes as part of OpenAPI 3.0 spec.

We have releases once in every 2 weeks, either we introduce new endpoint / make changes to the existing contract.

I have not been able to find a place holder in Open API 3.0 template to maintain change log / release notes.

The closest I see is is the "description" field under paths section.  Change Log / Release Notes grows over the time. 

I would love to get recommendations.

Thanks!
