The question of automatic dependency updates came up in our Slack channel the other day. There was a lot of nodding on how it is a good thing. Tools like Dependabot and Renovate were mentioned. Yet I was a dissenting voice. Why? The case for automatic dependency updates is simple and seductive: A bot would automatically scan your dependencies in your source code and create pull requests to update your libraries to the latest versions, sometimes even automatically merging it in.
