We are introducing a change to the pull request merge checks that will make them more reliable. Specifically, we will no longer allow pull requests to be merged while a build is in progress. It was possible for a pull request to be merged while some of its builds were still in progress and for those builds to fail after the merge has completed. This created an undesirable situation if build merge checks were enabled.

There are multiple ways to create a task on a pull request. They can be added from the sidebar, top-level pull request comments, file-level comment or inline comments. Once created, they all appear in the sidebar. On any repository, merge checks can be configured for any branch to only allow merging if all pull request tasks are resolved. This is a very useful functionality if some tasks are critical to be resolved before changes are merged.
