I guess he assumed that I get firmware ready for release, but instead I keep it only between a group of certain people. This happened, but not because of some select group of people that got a ready-to-use firmware just so they can have it before others and feel special. That was basically beta testing. If something unexpected appeared I would only have to fix their devices, and not those of other X persons that would want to try the firmware right away.
Right now there is no full-working beta build that I could share with people. Someone tested the higher volume thing once, then
@aceedburn and I were doing some testing regarding potential new "regions", that are bringing really interesting changes to the sound - you'll be able to hear the changes yourselves, for those ready to attack me regarding how changing regions are not actually doing anything. He went through at least a bootloop - the fix didn't work at first.
I understand that it's been quite some time since I've been mentioning what's to come, but hopefully it won't be too far in the future until the update comes.
So, a higher volume option (working only with Direct Source on, which can be triggered by pushing a certain button 3 times), a low-latency USB DAC mode, suitable for watching videos or other real time media (can be triggered with a different button in the same way), and a new and interesting sound available as a new "region" option (at least one more, excluding J3).
