The culmination of a number of ongoing fixes and patches, 1.0.6 is the logical extension for 1.0.5 - including a CRITICAL fix for a bug in timed bans. All users are urged to upgrade immediately.
In other news, we are releasing a technology preview of our 1.1 branch - totally unsupported, won't link to services, and not done yet - but feel free to take a look on a TEST network. If you run this in production, you are insane.
Thanks, and - enjoy.
