-- shadowircd-6.2.0

other changes
- change kicknorejoin to not be a config option and be hardcoded to 2 seconds
  because a longer time is kind of pointless.

-- shadowircd-6.1.0

new configuration options
- general::static_quit - Quit message to display for all users (not opers).
- general::no_part_messages - If this option is set to no, the ircd will not
  display PART messages/reasons from users.
- general::true_no_oper_flood - Turns off *ALL* flood protection for opers.
  Instead of command flooding being 4x what it is for a user with no_oper_flood,
  there is no limit at all. This option also allows opers to flood channels/users
  so if you do set it, be extremely careful.
- serverinfo::helpchan and helpurl - These are 2 config options that tell users,
  when they do /quote help (with no extra parameters) the official network help
  channel and a special URL for help. If these options are disabled, the users
  will just get the help index and that's it on /quote help.
- general::default_ident_timeout - Allows you to set the default ident timeout
  in the ircd.conf instead of it being hardcoded and only settable with /SET.

new commands
- CYCLE #channel - server-side CYCLE, also called HOP in some clients/servers.
  Parts the user from the given channel, then joins them to it immediately after.
  Enabled by loading extensions/m_cycle.

opers
- Override no longer alows overriding opers to talk through +q, +m, etc.
  If you need to talk through one of these modes, its recommended to remove
  the offending mode or give yourself voice/ops.
- OLIST now shows channel modes so opers can easily see which channels are
  +s and see which channels have oper-only channel modes set.
- RESTART and DIE now can be executed remotely. See the appropriate helpfiles
  for details.
- All module management commands (MODLOAD, MODLIST, MODUNLOAD, MODRELOAD and
  MODRESTART) can be executed remotely. See the appropriate helpfile for
  details.
- OMODE can now set and unset +ah.
- OJOIN now works with !#channel and %#channel.
- Staff channelmodes (+AO) now require chanops to set.
- OPERHOST option added to SET. You can now use SET to change the default
  operhost that operators get upon opering up, though like the 
  general::default_operhost config option it will not override the 
  operator::vhost config option.

other
- Added a strip_unprintable function to make evasion of cmodes +G and +K
  less trivial.
- Massive helpfile updates.
- Added SVSJOIN s2s command. This allows things like atheme's ns_ajoin
  to work on shadowircd.
- Added BAN stuff (propogated bans on burst) from charybdis trunk. This
  can be disabled and the old behavior can be used by setting the
  general::use_propogated_bans option to no.
- The --enable-small-net configure option is now enabled by default.
  If you wish to disable small net mode, pass --disable-small-net to
  configure.
- New channel mode adding API has been added from charybdis trunk.
- NOTICE/PRIVMSG @#channel and +#channel now go to admin/halfop as well
  as chanop.

-- shadowircd-6.0.0

new modes
- Add umode +C (no CTCP).
- Add umode +V, users with this mode set will never recieve channel invites
  from other users.
- Add umode +B which identifies users as being bots in /whois.
- Add umode +G which disallows users from messaging you unless you're both
  on at least one channel together. This can be "overridden" with /accept.
- Add cmode +T which blocks all notices to the channel.
- Add cmode +D which blocks all actions (/me's) from being sent to the channel.
- Add cmode +E which disallows channel ops from kicking users.
- Add cmode +N which disallows users from changing their nick while they're on
  a channel with this mode set.
- Add cmode +K (norepeat) which will block repeated messages, regardless of
  who they're from.
- Add cmode +G which blocks messages containing 50% or more capital letters
  from being sent to the channel.
- Add cmode +J which disallows a kicked user from rejoining within 'X' seconds
  of them being kicked, where 'X' is the variable of the channel::kick_no_rejoin_time
  configuration option.
- Add cmodes +a and +h (admin and halfop, respectively). There are 2 extra
  prefixes to more finely-grain the status of staff members in your channels.
  They can be enabled or disabled in the configuration file with the options
  channel::use_halfop and channel::use_admin.

new configuration options
- auth::autojoin - This option will specify what channels users in a matching
  auth {} block will automatically join on connect to your server/network.
- auth::autojoin_opers - This option will specify what channels opers in a
  matching auth {} block will automatically join on oper up (/oper).
- channel::cycle_host_change - This option defines whether or not users
  will cycle (part and rejoin) the channels they're in when their host changes.
  This can be annoying to some people, but disabling it can cause client desyncs.
- channel::host_in_topic - This option defines whether or not a host setter's
  full host or just their nick will be shown on /TOPIC.
- channel::use_local_channels - With this option, you can enable/disable
  support for local channels on your server/network.
- channel::exemptchanops - This option defines what channel modes channel
  operators are exempt from, channel modes usable in this option are: cCDTNGK.
- general::secret_channels_in_whois - This option defines whether or not opers
  can see secret channels that a user is in when whoising them. Secret channels
  will show up in the whois prefixed with *. If this option is disabled, opers
  will still be able to see secret channels a user is in with the /SPYWHOIS 
  command.
- Enabled a few popular extensions by default, added a few extensions to the
  example config files that were missing, add a few more services aliases
  by default, enable ip_cloaking by default and get rid of all the old
  ip_cloaking modules.

opers
- Users' umodes are shown when you whois them.
- swhois support - Adds a mostly free-form line of text to opers' whois
  if one is set in their operator {} block.
- custom operstring - Instead of showing the IRC operator or IRC administrator
  oper strings, you can customize what it shows in each oper's operator {}
  block.
- host-on-oper - Give a vhost to operators upon oper up. Can be defined
  generally, then the general option may be overridden by each operator {}
  block.
- operoverride - Oper override works very differently in ShadowIRCd compared
  to all other IRCd's which support oper override. In ShadowIRCd, to be able
  to override, you must have the oper:override privledge and you must then
  set umode +p on yourself. The p umode will automatically expire and un-set
  itself after a time set in the configuration option general::expire_override_time.
- immune - Adds cmode +M. Opers can set this on a channel (even if they don't 
  have ops) without the channel's ops or other users seeing (only opers see 
  this mode at all.) It disallows anyone in the channel from kicking opers.
- OACCEPT/callerid override - In ShadowIRCd 6, opers no longer can simply PM
  users that have umodes +g or +G set and the oper is not on their accept list.
  To allow opers to still be able to PM users in this situation, OACCEPT has been
  added. OACCEPT is a new extension that enables the command /oaccept <user> 
  which adds a piece of metadata to that use which will allow you to PM them.

other
- Changed default NICKLEN to 31 (from 15) to fit more closely with other
  IRCd's.
- Rebrand many things from Charybdis to ShadowIRCd.
- Move the m_force module to extensions.
- Add a metadata framework. Currently used for swhois, custom operstring, 
  OACCEPT, cmode +J, cmode +K.

-- charybdis-3.2.0

server protocol
- Apply +z to messages blocked by +b and +q as well. (new EOPMOD capab)
- Add new topic command ETB, allowing services to set topic+setter+ts always.
  (new EOPMOD capab)
- The slash ('/') character is now allowed in spoofs.
user
- Add can_kick hook, based on the ircd-seven one.
- Add cmode +C (no CTCP) from ircd-seven.
- Flood checking has been reworked.
- Fix op-moderate (cmode +z) for channel names with '@'.
- Add CERTFP support, allowing users to connect with an SSL client
  certificate and propagating the certificate fingerprint to other servers.
  Services packages can use this to identify users based on client
  certificates.
- Maintain the list of recently used targets (for the target change
  anti-spam system) in most-recently-used order, overwriting the least
  recently used target with a new one. This should be friendlier to users
  without giving spambots anything.
- Do not require target change slots for replying to the last five users to
  send a private message, notice or invite.
- Apply target change restrictions to /invite.
- Apply umode +g/+R restrictions to /invite, with the difference that
  instead of sending "<user> is messaging you" the invite is let through
  since that is just as noisy.
oper
- Add /rehash throttles to clear throttling.
- Send all server notices resulting from a remote /rehash to the oper.
- '\s' for space is now part of the matching, not a substitution at xline
  time, fixing various issues with it.
- Display o:line "nickname" in oper-up server notices.
- Fix sendq exceeded snotes for servers.
- SCAN UMODES: default list-max to 500, like a global WHO.
- Ignore directory names in MODRELOAD to avoid crashing if it is a core
  module and the path is incorrect.
- Tweaks to spambot checks.
config
- Add channel::only_ascii_channels config option to restrict channel names
  to printable ascii only.
- Add channel::resv_forcepart, forcibly parts local users on channel RESV,
  default enabled.
misc
- New mkpasswd from ircd-ratbox.
- Check more system calls for errors and handle the errors.
- Various ssld/libratbox bugfixes from ircd-ratbox. [some MERGED]
- Fix fd passing on FreeBSD/amd64 and possibly Solaris/sparc. [MERGED]
- Various documentation improvements. [some MERGED]
- Fix some crash issues. [MERGED]
- Add bandb from ircd-ratbox, which stores permanent dlines/klines/xlines/resvs
  in an sqlite database instead of a flatfile and does the storage in a
  helper process.

-- charybdis-3.1.0

- Remove TS5 support. No TS5 servers are permitted in a network with
  charybdis 3.1.0 or newer, except jupes.
- Replace oper flags by privilege sets (privsets). This adds an extra
  level of indirection between oper flags and operator blocks. /stats O
  (capital O) shows the configured privsets.
- Update libratbox and ssld from upstream and use it better.
- Add auth_user to auth{}. This allows specifying a username:password instead
  of just a password in PASS, so that a fixed user@host is not necessary
  for a specific auth{} block.
- Add need_ssl to auth{} and operator{}. This makes these blocks reject
  the user if not connected via SSL.
- Allow modules to provide simple channel modes without parameter.
- Remove restrictions on CNAME in the resolver.
- Make the resolver remember nonresponsive nameservers.
- Move nick collision notices from +s to +k.
- Add additional information to various server notices about server
  connections.
- Show throttle information in /stats t.
- Show rejectcache and throttle information in /testline.
- Show oper reason in /testline.
- Allow opers to see other users' umodes with /mode <nick>.
- SCAN UMODES GLOBAL NO-LIST MASK <mask> is no longer an operspy command.
- Also apply floodcount to messages to remote clients (except services).
- Remove user@server messages to local users. Sending such messages to
  remote servers is still possible, for securely messaging pseudoservers
  whether service{}'ed or not. The special oper-only syntax opers@server
  remains as well.
- Allow /list on a named +p channel. A full /list already included +p channels.
- Add operspy /topic.
- For remote rehashes, send error messages to the requesting oper as well.
- Disable autoconnect for a server with excessive TS delta.
- Disallow invites to juped channels.
- Warn about certain duplicate and redundant auth blocks.
- Make PRIVMSG/NOTICE behave as CPRIVMSG/CNOTICE automatically if possible.
- Allow +z messages from outside if a channel is -n.
- Allow coloured part reasons in -c channels.
- Add ircu-like WHOX support. This allows requesting specific information
  in /who and allows obtaining services login name for all users in a
  channel. XChat/Conspire use WHOX to update away status more efficiently.
- Allow opers and shide_exempt users to see hopcounts even if flatten_links
  is on.
- Rework ip_cloaking.
- Add the IP address to userlog, as in ircd-ratbox 3.0.
- Split cidr_bitlen into cidr_ipv4_bitlen and cidr_ipv6_bitlen.
- Allow using ziplinks with SSL connections. This is not as efficient as
  using OpenSSL's built in compression, but also works with older versions
  of OpenSSL.
- Fix an off by one error with zipstats processing, which could overwrite
  a variable with NULL causing a crash on some systems.
- Document some extensions in charybdis-oper-guide.
- Add more server protocol documentation.
- Add m_sendbans extension, SENDBANS command to propagate xlines and resvs
  manually.
- Add chm_sslonly extension, cmode +S for SSL/TLS only channels.

- A new compatibility channel mode, +S, has been added, it sets
  +b/-b $~z (extensions/chm_sslonly_compat.so).
- A new compatibility channel mode, +O, has been added, it sets
  +iI/-iI $o (extensions/chm_operonly_compat.so).
- Add remote D:lines. Note that these are not enabled by default.
- Remove EFnet-style G:lines. Noone appears to use these.
- Remove idle time checking (auto disconnecting users idle too long).
- Display a notice to clients when the IRCd is shut down using SIGTERM.

- Add keyword substitution to DNSBL reasons, making it possible to show
  things like the user's IP address in the reason.
- Use sendto_one_notice() more.
- Server notices about kills now include the victim's nick!user@host instead
  of just nick.
- Include real hostname in Closing Link message for unknown connections
  that have sent USER, in particular banned users.
- Add some documentation about the SASL client protocol.
- Change spambot, flooder and jupe joiner notices from host to orighost.
- Remove the last remains of server hostmasking (this made it possible to
  have multiple servers with similar names appear as a single server).
- Keep bitmasks of modularized umodes reserved forever to the letter,
  avoiding problems when reloading umode modules in a different order.
- Fix -logfile.
- Update to the new revision (v8) of the TS6 spec, this fixes problems with
  joins reversing certain mode changes crossing them. This interoperates
  with older versions.
- Put "End of Channel Quiet List" at the end of +q lists.
- Fix invisible count getting desynched from reality if the act of opering
  up sets -i or +i.
- Don't leak auth{} spoofed IP addresses in +f notices.
- Shorten quit/part/kick reasons to avoid quit reasons overflowing the
  client exiting server notice (from TOPICLEN to 260).
- Fix some cases where 10 char usernames lose their final character.
- Move username check after xline and dnsbl checks, so it will not complain
  to opers about clients who are xlined or blacklisted anyway (both of

  single ban exception existed on a channel.
- Tweak \s code a little.
- Add a minor clarification to the SGML docs.

- Search the shortest list (user's/channel's) when looking up channel
  memberships.
- Make the SID-collision notice look right under all conditions.

- Change behaviour of /stats p: now displays all staff members instead
  of local ones only.
- Make oper_list global, add local_oper_list for local traffic.
- Strip control codes from parts and quits.
- Add channel mode +c which strips control codes from messages sent to
  the channel.
- Add channel mode +g which enables free use of the /invite command.
- Add channel mode +z which sends rejected messages to channel ops.
  Could be useful for Q&A sessions or other similar events.
- Add channel quietmasks. These are recommended over the use of channel
  bans used to remove a user's ability to participate in the channel.
- Add channel join throttling mode, +j. Used to throttle channel join
  traffic, i.e. join/part flood attacks. Syntax: +j <joins>:<timeslice>
- Improvements to channel_modes(), from shadowircd -- allows for
  better construction of the mode string.
- Use the undernet throttle notice instead of bancache message when
  dealing with rejected clients. (stolen from ircu2.10.12)
- Add channel forwarding, via channel mode +f, behaves similarly to
  dancer-ircd version.
- Update example.conf to reflect AthemeNET changes. Original ratbox
  config is now reference.conf.
- Services account names are now tracked globally.
- Add channel mode +Q which disables the effects of channel forwarding
  on a temporary basis.
- Add channel mode +F which allows anybody to disable forwarding target
  authorisation, voluntarily on their channels.
- Make wallops behave like normal wallops.
- Add services aliases: /ns, /cs, /os, /nickserv, /chanserv, /operserv.
- Add simple hack that enables use of server password for automatic
  identify.
