xpra reports version as v0.0.6, will upgrade why cython builds 0.14 on ubuntu.
xpra v0.0.6 is very very old and is not found here, please upgrade to the version found on this website instead.
As for IPv6
, I haven't tested it yet, it should work (not sure about your syntax though!), and if not, fixing it should be simple (patches welcome!)
Fixed IPv6
support in r776, use the following syntax:
xpra attach ssh/::ffff:192.168.1.100/10
for ssh (with a display number), or for tcp (with a port number):
xpra attach tcp/::ffff:192.168.1.100/10000
Although the code is meant to support ":" as a separator, I would advise against it as it makes the connection string very hard to read (also untested - for that same reason).
