WordPress 7.1 enhances wp_get_abilities() with a built-in filtering pipeline, replacing the need for manual array_filter() calls scattered across consumers. The function now accepts an optional $args array supporting filtering by category, namespace, and metadata, plus callbacks for custom per-item logic and final result processing. Two new global WordPress filters (wp_get_abilities_item_include and wp_get_abilities_result) let plugins influence ability retrieval site-wide. The REST API abilities endpoint now delegates to this unified function and exposes the same filters as query parameters. Backward compatibility is maintained, but developers are encouraged to migrate manual filtering to the new arguments. The post also clarifies that filtering controls discovery only and does not replace permission_callback-based authorization.
