The following is a list of major changes between ircd-ratbox-2.1 and
ircd-ratbox-2.2.

Installation
------------
- Rewritten installation documentation.
- configure argument --with-maxclients is gone, we now use shell limits
  and dynamic /set maxclients option.

Config
------
- New option in general {};, hide_spoof_ips = yes|no;, controls whether
  spoofed ips are hidden to all opers.
- New option in serverinfo {};, default_max_clients = number;, sets the
  default maximum number of clients which can be changed later via 
  /quote set maxclients <number>

Client
------
- Removed rate limiting of /away

Oper
----
- TESTMASK now takes: TESTMASK <[nick!]user@host> [:<gecos>]
  Matching against all of the fields.
- TESTMASK can now perform ip comparisons, eg TESTMASK *@192.168.0.0/16
- New CHANTRACE command, which will perform an ETRACE of a channel if you
  are a member.  Operspy capable.
- New MASKTRACE command, taking: MASKTRACE [!]<[nick!]user@host> [:<gecos>]
  This essentially works like TESTMASK and is operspy capable.  In normal
  usage it will actually list local clients matching the mask, when used
  with operspy it will list all clients network wide.
- Klines for user@1.2.3.* etc are now munged to CIDR.
- New CHALLENGE system, see doc/challenge.txt and
  http://respond.ircd-ratbox.org for more information.

Misc
----
- Huge amounts of memory related cleanups.
- CPU optimisations to iline/kline/dline hash
- CPU optimisations to poll() network subsystem.
- Regained rtsigio network subsystem support, primarily for linux 2.4
- ircd -conftest option is now more "unix friendly"
- Improved logging when we disallow a servers linking.
- Server IP hiding is now hardcoded in.
