Tame Dependabot: Group your updates, slow the cadence, keep security fast

Maintainers of active repositories often face the dilemma of managing numerous Dependabot pull requests that update single dependencies, leading to a cluttered notification system where important updates might be overlooked. This issue was observed in Microsoft’s GCToolkit, where a significant number of commits were consumed by these updates. The solution involves modifying the dependabot.yml configuration to switch from a daily to a monthly update schedule and grouping multiple dependency updates into a single pull request, thereby reducing the noise and making updates more manageable. These changes ensure that routine maintenance is predictable and streamlined, while crucial security updates remain prompt and unaffected by the schedule. Additionally, the introduction of a default package cooldown prevents premature merges of potentially problematic releases by delaying version-update pull requests for three days, ensuring a safer integration process. This approach effectively balances routine updates with urgent security needs, resulting in a more efficient review process and reduced maintenance overhead.
