It is already out. Not sure why it’s not updating some sites, my demosite was not updating as well. I changed the version in the plugin editor manually to make it update. WordPress maybe checks only every 24 hours or so if there already were a update recently or they push updates out 1by1.
Go to Plugins -> Editor -> Advanced Responsive Video Embedder -> advancedresponsivevideoembedder.php and change the line that says
* Version: 2.6.0
to * Version: 2.5.0
that worked for me to force the update showing up.
But honestly this should happen automatically soon, sometimes you have to click a but around in the admin of wordpress to make it show up the updates.
Or just grad it from here and upload it manually.

Just saw in the other thread that you already got it, so all you needed is a little patience, I had the plugin already updated here and then posted the message that its fixed in 2.6.1 ??
