Based on this website, there was a new episode released today (June 6th, 2015) called "Confronting the Darkness!".
Here's a link to watch: http://gogoanime.tv/pokemon-xy-episode-66
(Sorry about the Japanese language, but there's English subtitles. If you insist on an English version, you'd have to wait a while, since it was just released in this region. They only have it in Japanese because it's been released there first)
Hope I helped! :)
