The two may coexist (e.g. <code>min-release-age</code> inyour <code>.npmrc</code> is preserved when npm internally spawns a sub-process with<code>--before</code> while preparing a <code>git:</code> or <code>github:</code> dependency); when bothapply, <code>before</code> wins within a single source and across sources the standardprecedence rules apply.</p><p>Packages whose names match <code>min-release-age-exclude</code> are exempt from thisfilter.</p><p>This value is not exported to the environment for child processes.</p><h4 id="min-release-age-exclude"><code>min-release-age-exclude</code></h4><ul><li>Default:</li><li>Type: String (can be set multiple times)</li></ul><p>A list of package names or <code>minimatch</code> glob patterns that are exempt fromthe <code>min-release-age</code> (and <code>before</code>) filter.

Patterns match againstthe package name, so <code>@myorg/*</code> matches <code>@myorg/shared-utils</code>.</p><p>Excluding a package does not change which registry it is fetched from.
