What is a "grouped update" in Dependabot?

By default, Dependabot opens one separate pull request per dependency update, which can mean dozens of individual PRs for a large project with many outdated packages. Grouped updates let you configure Dependabot to bundle multiple related dependency updates into a single pull request instead, based on rules you define (like grouping all packages matching a name pattern, or all minor/patch updates together).

updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    groups:
      dev-dependencies:
        dependency-type: "development"
      minor-and-patch:
        update-types: ["minor", "patch"]

This significantly reduces PR review overhead for teams managing many dependencies, consolidating what might otherwise be twenty separate low-risk patch-update PRs into one combined PR to review and merge, while still keeping genuinely higher-risk updates (like major version bumps) separate if configured that way.
