Workzone lets you configure auto-merge to trigger a merge automatically even if not all reviewers have approved. Specify a percentage of needed approvals and once the quota is reached, the PR will be merged.
Workzone auto-merge warns if Stash Pull Requests for a repository are configured to have a minimum number approvers - then auto-merge may not be successful. When using Workzone auto-merge it is not recommended to enforce Stash Pull Request required approval numbers.
Workzone is now compatible with Stash 2.2 through 2.7.x. Support for Stash 2.1. has been dropped due to dependency on the Stash required approvals hook that was introduced in Stash 2.2.
