In version 5 the render_field filter works correctly if you’re targeting globally, but if you try and define down to a specific type, it doesn’t work. ‘acf/render_field’, works, ‘acf/render_field/image’ doesn’t.
Thanks,

I recently just ran into this myself and did some digging around in the code. It appears the doc on this filter is incorrect.
The actual hook looks like acf/render_field/type={$field_type}
, which is consistent with all the other ACF filters.
