I just committed ircu2.10.11.beta.15. One of the changes that everyone must be aware of is that the reply for /USERIP is now 340, not 307. This was necessary to resolve a conflict between the meaning of the numeric in Undernet ircu and other irc server versions.
Another change is the addition of a new channel mode, +r. This feature works with the ACCOUNT feature introduced earlier in the release cycle. Basically, if a user who's ACCOUNT has not been set attempts to join a channel that is +r, he will be refused with ERR_NEEDREGGEDNICK (477). (The error reply is formatted similarly to ERR_INVITEONLYCHAN and similar replies.) This can be overridden by /INVITE'ing the user to the channel. (In fact, until X starts issuing ACCOUNT directives, +r can be considered a synonym for +i.) The new channel mode has been added to the 004 reply and the feature list. -- Kevin L.
