* Length of channel mode lists (ban / ban-except / invite-except) is now restricted to the limit in config.
* Support `MAXLIST`, `MAXTARGETS`, `MODES`, `TARGMAX` in `RPL_ISUPPORT`.
* Added support for IRCv3 capability [`chghost`](http://ircv3.net/specs/extensions/chghost-3.2.html).
* Roleplaying commands, both inside channels and between clients.
### Changed
* In the config file, "operator" changed to "opers", and new oper class is required.
