--- shadowircd 6.4.0
-* This is primarily made up of backports from Charybdis 3.4.0
-
-server protocol
-- Add channel ban forwarding <mask>$<channel> much like ircd-seven. Local use
-  of this is controlled by the channel::use_forward config option.
-- Allow RSFNC (forced nick change from services) to change a nickname's
-  capitalization only.
-- Add ENCAP TGINFO to propagate IP addresses that exceeded target change
-  limits (these get a lower limit when they reconnect). The message's source
-  is the user that exceeded the limit and one parameter "0" is required.
-user
-- Allow mode queries on mlocked modes. In particular, allow /mode #channel f
-  to query the forward channel even if +f is mlocked.
-- Consider bogus CTCP ACTION messages (without action text) CTCP (for
-  cmode +C).
-- Apply colour stripping (cmode +c) and CTCP checking (cmode +C) to messages
-  to @/+ channel as well.
-- Channel mode +c (and other places that disallow colour codes) now also strip
-  ASCII 4 (a different kind of colour code).
-- Add an error message (numeric 743) if a ban mask is invalid.
-- Extract the underlying IPv4 address from 6to4 and Teredo IPv6 addresses.
-  Show it in a remote /whois and check channel bans, quiets, D:lines and
-  K:lines against it. Note that ban exceptions and auth{} blocks are not
-  checked.
-- Send ERR_TOOMANYCHANNELS for each channel join that fails due to channel
-  limits, instead of one per JOIN command.
-- Add account-notify client capability to notify clients about logins and
-  logouts of users in common channels. See doc/account-notify.txt.
-- Add away-notify client capability. See doc/away-notify.txt.
-- Add extended-join client capability to add account name and ircname to JOIN.
-  See doc/extended-join.txt.
-- Disallow wildcarded nicknames in "hunted" parameters like /stats and /motd.
-- Disallow mIRC italics in channel names when disable_fake_channels.
-- Add AUTHENTICATE EXTERNAL support, allows SASL authentication using an SSL
-  certificate fingerprint.
-- Allow channel::kick_on_split_riding to protect channels with mlocked keys.
-  This works with atheme-services 5.2.0 or newer.
-- The NICKLEN token in 005 now only specifies the maximum nick length for
-  this server/user. The MAXNICKLEN token specifies the maximum nick length
-  any user can have.
-- Disallow '$' in usernames as this may cause problems with ban forwarding.
-- Allow normal users to perform /privs on themselves, showing some privileges
-  from the auth{} block.
-- Rate limit high-bandwidth commands, in particular /who <channel>.
-- Rate limit /away to help avoid flooding via away-notify.
-oper
-- Add operspy for /list.
-- Add /stats C to show information about dynamically loaded server
-  capabilities.
-- Add a server notice to snomask +b if a user exceeds target change limits.
-- Add missing server notice for kills from RSFNC and SVSLOGIN.
-config
-- Add support for IPv6 DNSBLs. A new "type" option specifies the IP version(s)
-  for which each DNSBL should be checked.
-- Make flood control settings configurable by those who know exactly what they
-  are doing.
-- Add serverinfo::nicklen config option to limit the nick length for local
-  users. Different values of this option do not break the server protocol.
-- Add general::away_interval to allow configuring /away rate limiting.
-- Add listener::defer_accept to delay accepting a connection until the client
-  sends data. This depends on kernel support. It may break BOPM checking.
-- Add general::resv_fnc to forcibly change nicks of local users that match a
-  newly set nick RESV, default enabled.
-- Add extb_usermode extension, $m:+-<modes> extban matching against umodes.
-- Extend extb_oper extension to allow matching against oper privileges.
-misc
-- Work around timerfd/signalfd brokenness on OpenVZ.
-- Add --with-custom-branding and --with-custom-version configure options to
-  help forks/patchsets distinguish themselves.
-- Ensure SIGHUP and SIGINT keep working after a SIGINT restart.
-- Remove broken GnuTLS support. SSL/TLS is now only provided using OpenSSL.
