Added support forvkvideo.ru
domain.

Updated Facebook to fix a potential issue with usernames that contain a dot .
Updated lazy loader. No functional change intended.
Added support for Nacho Video.
An issue has been reported in the discussion thread. I can't reproduce it but this hotfix should mask its symptoms until the cause is found.
If you haven't experienced any PHP errors, you don't have to update.
