# XF 2.2XF\FindNew\AbstractHandler->filterResults BC break - 2.2 Beta 4

Please note that we will be changing the signature of `\XF\FindNew\AbstractHandler->filterResults` to take an `AbstractCollection` instead of an `ArrayCollection` as follows:

Old:
PHP:
``protected function filterResults(\XF\Mvc\Entity\ArrayCollection \$results)``
New:
PHP:
``protected function filterResults(\XF\Mvc\Entity\AbstractCollection \$results)``

To work with this, `\XF\Entity\Finder->fetch` now also returns an `AbstractCollection`.

This change breaks backward compatibility, hence the notice here.
