## Timeline of updates

- **resolved** 2020-08-28 22:00 UTC: From August 28, 2020 15:00 UTC to August 28 20:00 UTC, we updated a dependency that caused issues with CircleCI configurations that included a high number of YAML aliases. This could have caused builds to fail and scheduled workflows to not run and potentially be unscheduled. We reverted that change and all builds should be running as expected. Customers may need to push a new commit to their project repository to reschedule any canceled scheduled workflows.
