It can use improvements though. I have been distracted by broadcasting/robotics recently, but I would
love to come back to this.

Hi,
The reason I've released 0.96 is that it looks like a rock solid version,
and I'm planning to break things. More specifically, I've just finished
doing a straightforward port to Pion WebRTC v4, and I'm planning to make
the following changes to Galene's protocol:
- use a separate RTX track for retransmissions;
- use TWCC instead of REMB for GCC congestion control.
The RTX track will allow browsers to do more precise accounting of packet
loss, which should improve behaviour under packet loss. Replacing our
home-grown implementation of REMB with Pion's implementation of TWCC will
hopefully improve behaviour on congested links (it will no longer be
necessary to manually switch to "Send: low" when on a slow link), but more
experimentation is needed.
This work is going on in the "pion-v4" branch, which I'll merge into master
when I'm satisfied it doesn't break anything.
Did delay and not just loss make it into pion?-- Juliusz
