It's not us who are holding back the update. It's GGG. We have handed off the project files for v1.6.5 a few months ago, they are still doing checks for its release on Steam. We should be near the end of the process by now so it should happen sometime next month.
Here's the situation regarding Update 1.6.5 on Steam. It was released but removed the very next day. It seems there's a bug causing double attacks. (update- No. My mistake- the double attack occurs because the new patch version is incompatible with Visustella Battle Core) GGG has promised to fix everything and release a full update in the near future.
