Commit c8ef6c5354 for wordpress.org
commit c8ef6c53549181f86436784f36194e8dc938e3bc
Author: Weston Ruter <weston@xwp.co>
Date: Mon Nov 3 23:47:33 2025 +0000
Plugins: Add missing `$priority` parameter to `has_filter()` and `has_action()`.
This brings `has_filter()`/`has_action()` in parity with `add_filter()`/`add_action()` and `remove_filter()`/`remove_action()`, all of which support a `$priority` parameter.
Props westonruter, swissspidy.
Fixes #64186.
See #64178.
