Acf_repeater is not working with 4.1.0

This (and the ACF date one) is a critical issue that have broke many live websites on my side. Why did you not test it before releasing the last version ? I love L&L but this is not the first time this kind of situation happens. Could you please change the way you test new code evolution before pushing a new release of the plugin on the Wordpress directory ?
The impacts are really huge on my side. thank you
