If I approved pull request and later need to approve it again, it would be nice to see changes only from the last time.
I can use compare branches to see diff between commits (https://bitbucket.org/.../branches/compare/BRANCH%0DCOMMIT) but there is a problem. If master was merged into the branch then in diff I will see all changes made in master. They are completely irrelevant.
Is there a way to see diff between two commits excluding master?
