Answer 1

The ability to Dismiss stale pull request approvals when new commits are pushed is a setting under Require pull request reviews before merging in the branch protection settings. This is disabled by default.

Does this also invalidate approval if the branch is rebased? – Gualterio

@Alper, yes. Although for the last week I see that our approvals were not dismissed despite any changes to the PRs. Maybe a temporary glitch because it's been working for well ages. Note though that since some time the approval is not dismissed on rebase in case the actual diff stays the same. – Leu

Answer 2

This isn't currently offered.

You can create an application that listens for push webhook events, queries the API for all Reviews for a Pull Request, and dismisses any that are APPROVED.

Here is a Ruby script you could host on heroku.
