⚠️ Renovate's pin functionality does not currently wire in the release age for a package, so the Minimum Release Age checks can apply. You will need to manually validate the Minimum Release Age for these package(s).

Add the preset :preserveSemverRanges to your config if you don't want to pin your dependencies.
