Subject: [PATCH] Fix version filtering and deprecation warning

The original `reject` had no effect due to matching full paths and
comparing `false` against a regular expression.

This change replaces a non-functional `reject.map` with `map.grep`
for correct filtering and resolves a deprecation warning.
