We’re introducing calendar-based versioning for our REST API, so we can keep evolving our API, whilst still giving integrators a smooth migration path and plenty of time to update their integrations.

This will be reflected in the conversation timeline:
Users who aren’t collaborators on the repository won’t be able to comment further:
Repository collaborators will still be able to continue the conversation on a locked thread if they’d like.
Remember that, in addition to conversation locking, you can also block or report users to help keep GitHub a safe community for everyone.
