@ -12,10 +12,12 @@ New release of Oragono!
### Added
* Added `REHASH` command.
* Added ability to message channel members with a specific privelege (i.e. support for `STATUSMSG`).
* Added ability to enable and disable SASL.
* Added support for IRCv3 capabilities [`cap-notify`](http://ircv3.net/specs/extensions/cap-notify-3.2.html) and [`echo-message`](http://ircv3.net/specs/extensions/echo-message-3.2.html).
### Changed
* Server operators no longer have permissions to do everything in channels.
### Removed
