Most important changes in 2.11 server grouped by who most benefits from the
feature or who should look at it more carefully.

All:
	* Nicknames cannot contain [|]^{\} chars. (This restriction will be
	  removed in 2.11.1)
	* Channel names cannot contain {\}~ chars. If used (or from remote),
	  they will be changed to [|]^ accordingly. (This restriction will be
	  removed in 2.11.1)
	* New channel list type: R (aka reop list). With the same syntax and
	  behaviour as beI, it serves as a hint list for reopping opless
	  channels. Note that clients cannot set it yet, not until 2.10 exist.
	* CIDR support in +beIR channelmodes.

Client:
	* When collision occurs, clients get their nicks forcefully changed
	  to their UIDs. (Note: this requires no 2.10 server on the path
	  between these two clients!)
	* Clients can use "NICK 0" to get their UID as a nick. Works during
	  registration, too.
	* Channels now keep information who and when set the topic.
	* LIST (if allowed) does not disconnect if client's sendQ fills.
	* WHOIS now shows the time user signed on.
	* LUSERS shows local and global usercount maximum.
	* INVITE overriding ban shows inviter's n!u@h in channel notice.
	* Support for text representation of user modes in USER command
	  during registration.
Server:
	* New server to server protocol, based on Unique IDs
	* Operator broadcast message syntax has been changed to:
		$$*.mask - message all users matching given server mask
		$#*.mask - message all users matching given hostname mask
	* Essential notices were moved from &LOCAL to &NOTICES
	* Possibility of using port "0" in manual CONNECTs (even remote);
	  ircd will use port from ircd.conf
	* Added DelayedKill feature to make ircd more responsible on rehash
	  on big servers with many clients and many klines.
	* Added new wildcard character '#' matching any digit.

Admin:
	* Ability to specify outgoing IP in C: line.
	* I:line now requires both addr and name fields to match.
	* I:line flags
		F - fall-through to next I: if password did not match.
		R - restricted.
		I - restricted, when client has no ident.
		E - client is exempted from K: lines.
		N - disable resolved hostname to be used.
		D - restricted, when client has no reverse DNS.
	* Reject reason sent to client can be specified in iauth.conf.
	* Client's username and hostname are checked for valid chars.
	* C:lines can have negative ports to disable autoconnects; these
	  will be used when CONNECT with port "0" is used.
	* STATS ? shows quick information about connected servers.
	* STATS f, avaible to local operators only, shows detailed
	  information about client TCP connection.
	* -t option (foreground mode) is now avaible even without DEBUGMODE
	* o: and O: in config are now swapped to be consistent with usermode.
	* Added SET command which makes possible to fine-tune certain
	  ircd values during runtime (like dbuf poolsize and autoconnect).
	* Stats Z no longer computes real memory statistics unless DEBUGMODE
	  set.
	* Stats l/L shows count in Bytes, not kBytes.
