• +a (away) user mode

    This user mode is used to propagate users' away status between servers.

  • added channel mode +e (exceptions to bans).

  • added channel mode +I (invitations).

  • invites can now be used to override channel bans and limit.

  • banned users cannot speak on channel without +o/+v.

  • ! channels introduced (can't be collided);

  • NJOIN for 2.10 - 2.10 communication on connect bursts instead of the combined JOIN/MODE introduced by 2.9 (and now deprecated)

  • a slave process is now used to authenticate incoming connections.

    The slave's modular design makes it easy to add new authentication modules.
