+A new setting added: `pnpm.peerDependencyRules.allowAny`. `allowAny` is an array of package name patterns, any peer dependency matching the pattern will be resolved from any version, regardless of the range specified in `peerDependencies`. For instance:
+
+```
+{
+  "pnpm": {
+    "peerDependencyRules": {
+      "allowAny": ["@babel/*", "eslint"]
+    }
+  }
+}
+```
+
+The above setting will mute any warnings about peer dependency version mismatches related to `@babel/` packages or `eslint`.

+The `pnpm.peerDependencyRules.ignoreMissing` setting may accept package name patterns. So you may ignore any missing `@babel/*` peer dependencies, for instance:
+
+```json
+{
+  "pnpm": {
+    "peerDependencyRules": {
+      "ignoreMissing": ["@babel/*"]
