Unreal3.2-beta18 Release Notes
================================

==[ GENERAL INFORMATION ]==
* If you are upgrading, make sure you run ./Config and make clean before doing make
* The official UnrealIRCd documentation is doc/unreal32docs.html
   online version at: http://www.vulnscan.org/UnrealIrcd/unreal32docs.html
   FAQ: http://www.vulnscan.org/UnrealIrcd/faq/
   Read them before asking for help.
* Report bugs at http://bugs.unrealircd.org/
* This release adds a lot nice new features and fixes most win32 crashes.
* If you use SSL, make sure you use at least openssl 0.9.7c / 0.9.6k (released
   today at Sep 30), some important security issues have been fixed.
   The win32-ssl version already includes the fixed version (unless you download it
   before this announcement).

== [NEW FEATURES (see unreal32docs.html for more information) ]==
* ChannelMode +f has been changed a lot, it's an advanced anti-flood mode now.
   It can protect against: joinflood, ctcpflood, msgflood, nickflood and knockflood.
   For example: +f [30j,50m]:15 means max 30 joins and 50 messages are allowed per
   15 seconds, if the max joins limit is reached the channel is automatically put +i,
   if the messages limit is reached the channel is put +m.
   For more info see: http://www.vulnscan.org/UnrealIrcd/unreal32docs.html#feature_antiflood
   You might want to enable it by default via set::modes-on-join.
* The /stats system has been recoded, some new features:
   * extended flags for shun and kline, for example:
     "/stats G +m *aol.com" will display all glines matching *aol.com.
   * support for long flags, like: /stats exceptban
* Finally support for up to 32 new channelmodes, all of which can be done in modules
   (currently disabled by default). SnoMask module support has been added as well.
* Added nickflood protection, set::anti-flood::nick-flood, this is
   enabled by default and set at 3:60 (max 3 nickchanges per 60 seconds).
* The win32 editor has been improved: better handling of mIRC codes, short motd editting,
   goto button, find text feature, etc..
* A new deny channel :: warn option, this will inform opers (with eyes snomask) that the
   user was trying to join the forbidden channel.
* official-channels support, these channels are shown in /list even if they have 0 users,
   you can also a default topic which is shown in /list.
* Added badwords all { }, you can use this instead of using a badwords channel,
   badword message and badword quit block for the same word.
* Added set::channel-command-prefix to allow channel text which starts with specific
   characters to be sent to +d clients (for in channel commands).
* You can now set the default bantime for a gline/kline/gzline/.. in set::default-bantime
   (like for /gline *@*.something.net)
* A README file has been added.
* Will now strip/block color codes in quits if the user is in a +S/+c channel.

==[ CHANGED ]==
* We will now error at too large cloak keys (>2147483646)
* away-flood configuration now works just like nick-flood,
   it's also enabled by default at 4 per 120s.
* badword filtering is now only done at the first server (source),
   this can reduce CPU usage a lot, especially at hubs.

==[ MAJOR BUGS FIXED ]==
* The buggy windows resolver has been replaced with the *NIX resolver,
   the win-resolver was the main cause of unrealircd@windows crashes.
* services-related crashbug found 24h after beta17 release :(
* ban version crash
* UnrealIRCd should now be able to run fine at PowerPC.
* No security related fixes this release.

==[ MINOR BUGS FIXED ]==
* oper::swhois wasn't working correctly (/whois from remote servers).
* /silence with cloaked hosts
* trafficstats were sometimes incorrect (/stats T and /HTM).
* multiple channelmode +(m)u fixes, most of them were multiserver related.
* IPv6: FreeBSD has support for ::ffff:1.2.3.4 alike IPs disabled by default,
   we will now spit out some information about this if binding to such IPs fails.
* Fixed a chroot bug
* Made /restart work at windows in service mode.
* A few +b/+e bugfixes
* Allow o/a/q'd people to nickchange if banned
* Added some missing info to /stats
* etc..

Changelog since beta17:
- Modified './update', now points to docs until we have a new update thingy.
- Fixed bug with /list and '?' wildcard, reported by maGGus.
- Fixed a few fdlist bugs in SVSMODE/SVS2MODE found by Aither.
- IPv6: added warning if a ::ffff:a.b.c.d type addr doesn't work since this "feature"
   is disabled by default at newer *BSD versions. Also improved another warning.
- Added set::channel-command-prefix to allow channel text which starts with specific characters
   to be sent to +d clients (for in channel commands).
- Added a README
- Added some checking in fdlist add/remove functions.
- Updated docs a bit (how-to-get-support/FAQ link style).
- Rewrote the win32 editor handling of mIRC codes. The new system should be more stable,
   and it supports more features, such as background colors. Just a note, the editor should
   be able to display any mIRC code without problem, however, some codes may be changed once
   you save the file. For example, reverse is replaced with ctrl+k0,1 and color code 99 is
   treated as a 1 if used for a text color and 0 if used for a bgcolor. This might cause
   problems when displaying in some clients, however not all clients support color code 99.
   As for the reverse, if I can come up with a decent way to still keep the original reverse
   code, I will change it to do that. So in short, if you need the color codes to stay
   _exactly_ the way they are, then you shouldn't use the editor on that file. Also, color
   codes that are 0..9 are translated to 2 digits, ie "2" becomes "02" this is to prevent
   problems when a number follows directly after the color code.
- Added support for editting short motds in the win32 editor.
- Added a goto button on the win32 editor toolbar.
- Made the win32 editor window maximizable.
- Added a find text feature to the win32 editor.
- Added HOOKTYPE_LOCAL_OPER (first param = aClient of oper, second param = 1 if the user
   just became an oper, 0 if they just -o'ed)
- Added a system to allow modules to create snomasks using functions SnomaskAdd and SnomaskDel
- Fixed ban version crash and another read-after-free.
- Fixed problem with make custommodule and multiple EXLIBS arguments (EXLIBS="-la -lb -lc").
- Fixed a bug with +b and +e involving how trimming should occur when a mask is too long.
   (#0001103) reported by Troco.
- Fixed a bug in aliases reported by darko``
- Updated help.conf and unreal32docs.html (#0001111) reported by SciFi, AngryWolf, and Zerwas.
- Cleaned up some code for /die under Windows
- Fixed ircd.c compile error discovered by Ravage
- Made unreal work with Linux under PPC (#0001105,#0000929) reported by drevlan and Cruiser
   and thanks to drevlan for donating a linux ppc shell to help track down the problem
- Fixed a problem where Unreal would sometimes die without outputting information about the
   crash under Windows
- Made /restart work under Windows in NT service mode.
- Fixed a documentation typo (#0001027) reported by Soldier007
- Fixed a bunch of logging problems reported by LRL (#0001034).
- Fixed a problem with a fix for +b/+e reported by AngryWolf (#0001117)
- Fixed a documentation typo reported by Z3l3zT (#0001066)
- Clarified what ban server {} does, suggested by Joolz (#0001110)
- Fixed a problem related to crontab reported by LRL (#0001034)
- Fixed a problem in PPC detection
- Will now error at too large cloak keys (2147483647 and greater) because it's dangerous
   and could cause cloak key differences (ex: mixed ia32&ia64 networks).
- Some minor text/documentation fixes.
- First big part of modulized extended channelmodes system:
   - Adds room for at least 32 (new) channel modes.
   - Supports both paramless and 1-parameter modes.
   - Modulized: modules can add new channelmodes, but are unloadable (permanent).
   - Everything is ifdef'd, and EXTCMODE is disabled by default in config.h
   - It will send CHANMODES= in the PROTOCTL message on server link, this enables
     servers and services to see which modes are supported and of what type
     they are (1-parameter, paramless, etc).
   And now the bad part:
   - The system has not been fully tested, it will contain bugs (for example I'm
     aware of some memory leaks).
   - A few features are missing: warning/error on linking if chanmodes mismatch, unloading
     of channel modes (not planned soon), 005 broadcasts on change and maybe more..
   - The function (and maybe variable) names will be changed in the next weeks/months
   - You should be carefull with parameter modes + services. Things will get desynced
     if services don't recognize it's a parameter mode. This also applies to clients
     without 005 CHANMODES= support.
   - No documentation
   I really suggest module coders to wait a few weeks till the system is ready..
   In the meantime, don't report bugs or ask for support on this.
- Fixed bug with SWHOIS: oper::swhois wasn't broadcasted correctly which made it
   only show up in local (or server) /whois, reported by format (#0001141).
- minor m_kick tweak.
- Fixed bug in /silence regarding cloaked hosts, reported by kuwatog (#0001157).
- Fixed a problem with a Sleep call on win32
- Rewrote the /stats system. The new system allows for long flags for example
   /stats gline to list glines rather than just /stats G (old flags are still
   supported). Additionally, for glines an extended syntax is now supported allowing
   more refined searches. /stats G +m *@*.aol.com lists only glines that match that
   mask. For more info do /stats ?.
- Added stats flags for except throttle and ban version blocks
- stats bugfixes: a null pointer crash and a '/stats k' bug.
- Fixed a couple of problems in the new stats system
- Fixed another stats problem, reported by Angrywolf (#0001163)
- Rewrote the usermode module interface to be more stable and consistent with other
   module functions. New functions are UmodeAdd and UmodeDel (backwards compatibility
   is available for the old functions).
- Fixed a bug in the snomask and umode system dealing with removing flags
- Added two module functions ModuleGetOptions and ModuleSetOptions to retrieve/toggle
   module options
- Fixed a bug effecting +k/+L where you could /mode #chan +k test, /mode #chan +k test
   and each time it would send a mode change (#0001170) reported by Airnike.
- A few documentation updates/fixes
- 005 CHANMODES= set back to original value before extcmode merge
- made some functions in channel.c non-static so module coders
   can use them (they are not defined in the header files [yet] however).
- fixed 2 minor oob write issues
- Fixed a bug with stats l/L
- Updated example.conf with a more strict default oper-only-stats.
- Made '/stats S' and '/stats Z' oper only again (always).
- Hopefully fixed incoming/outgoing rate in /stats T. Only the stats of the first
   listener was counted instead of the total. This also explains why on some (many?)
   ircd configurations it always showed 0.00 kb/s and why HTM (high traffic mode)
   was never kicking in.
- A few doc updates (example.conf).
- Added EOS command (End Of Sync), which is sent between servers after a server has
   succesfully synced (after introducing of channels, users, etc). This way we can
   easily distinct between linked servers and a connecting server.
   This is needed / very helpful for: snomask +F, new +f anti flood system, prolly
   other things as well. Services don't support this command, but it's not
   needed atm since +F/+f both ignore U lines.
- Internal: changed 2 MyMalloc's to MyMallocEx (mem zerofill).. nothing was currently
   affected by this but it's easy to forget if you add new stuff.
- Fixed minor /WALLOPS bug reported by Praetorian_ (#0001195).
- Internal code cleanups: EOS var rename, got rid of old UnknownUser structs, moved
   anti away flood to new flood struct.
- Changed away flood configuration to set::anti-flood::away-flood <count>:<period>.
- Added nickflood protection, can be set in set::anti-flood::nick-flood <count>:<period>
   to allow max 'count' nickchanges per 'period' seconds. The default is 3 per 60s.
   As usual, the nickchange limiting does not apply to ircops.
- Allow o/a/q'd users to nickchange if banned (#0001150).
- Added badword all { }, this will add the badword to the badword channel, badword message
   and badword quit lists... could be useful :p.
- Little config.h cleanup (removed obsolete non-working defines).
- Allow opers to talk in channel even if +m (#0001109).
- Implemented the *nix resolver under windows. This should solve 90% of the problems that
   exist in the Windows version. There may be some problems with the resolver that still
   need to be worked out, however it should be much more stable than before. Some of this
   code is based on the ircu Windows NT port by run.
- Fixed a problem with /quote dns i
- Rewrote a whole bunch of stuff in the extcmode code
- Extended the module system to allow better error reporting using ModuleGetError and
   ModuleGetErrorStr
- Changed channel mode +f, it's a much more advanced antiflood mode now.
   It can protect against joinfloods, ctcpfloods, nickfloods and message/notice floods.
   For example +f [10j]:15 allows 10 joins per 15 seconds, if the limit is reached the
   channel is set automatically +i (invite only) by the server.
   You can read more about it in section 3.12 'Anti-Flood features' of unreal32docs.html:
   http://www.vulnscan.org/UnrealIrcd/unreal32docs.html#feature_antiflood
   This change can cause desynch problems if both old+f and new+f servers are used on
   a network. It's (currrently!) possible to use the old +f system if you undef NEWCHFLOODPROT
   in include/config.h.
- Fixed ~5 compiler warnings at *NIX and ~20 at windows. Some of them _could_ have caused problems.
- Moved EOS debugging code to DEBUGMODE.
- Fixed a channel sync bug reported by thilo&Rocko (#0001218).
- Fixed minor config parser memleak reported by AngryWolf (#0001214).
- Fixed bug regarding hidden opers + m_whois cleanup (#0001208).
- Made SSL users unable to -z themselves, also added 2 flags to /stats S,
   reported by Joolz (#0001200).
- Fixed problem with opers having both 'admin' and 'coadmin' causing double-notices (#0001043).
- +f now also allows you to specify an 'action'. For example +f [30j#R]:15 will set the
   channel +R (instead of +i) if more than 30 joins in 15 seconds are reached.
   The following combinations are allowed: c#m, c#M, j#R and m#M. (docs will be updated later)
- Probably fixed a bug regarding 'setting mode' notice with +f (was sometimes sent to non-chanops).
- Fixed multiple chmode +u bugs: remote join, netjoin, +mu relay between servers, kick and
   a part bug. Most of them reported by Lx (#0001097).
- Fixed a bug in +f + modes-on-join + 't' subfloodtype, reported by Rocko (#0001228).
- Fixed a crashbug with +f and services, reported by Rocko (#0001227).
- And another +f + modes-on-join one...
- Made anti away flood system work just like anti nick flood (#0001205).
   NO_FLOOD_AWAY is now enabled and away-flood is set to 4 per 120s by default.
- Fixed a double OperOverride notice bug reported by DukePyrolator (#0001180).
- Doc fixes/updates reported by Angrywolf (#0001163, #0001176).
- Fixed a /rehash crash regarding badword all & regex badwords, reported by Angrywolf (#0001230).
- Fixed an old bug where allow::hostname localhost (or *@localhost) didn't work (#0001115).
- Fixed a chroot bug, reported by iceblade (#0001112).
- Badwords filtering is now only done for local clients, previously every server was filtering
   the message. This will reduce CPU usage, especially at hubs (#0001022).
- Will now strip/block color codes in quits if any channel the user is in has mode +S/+c.
- Temporarely added trace code for hunting down negative operator counts (#0001155).
- Made it so that with +M and user not +r and not voice/halfop/ops/etc the part message isn't
   shown, just like with +m.
- Added warn option to deny channel, this will send a notice to the eyes snomask when a user
   attempts to join. Suggested by Joolz (#0000992).
- Added clientsonly/serversonly/ssl/java flags to /stats P (#0000992).
- Added official-channels block. These channels are listed in /list even if they have 0 users.
- Fixed a crashbug introduced by +mu fixes 3 days ago (#0001237).
- Fixed a typo where /knock would say the channel is +I if +V is set, reported by Certus
- Improved SSL error msg sent to junk snomask.
- Fixed Q:lined nickname msgs during linking and a debug fix.
- Fixed a SVSMOTD crashbug (removing of motd).
- Fix-for-fix-for-+mu-fix (it was still crashing)... don't ask.
- Minor +f code tweaks.
- Added checks for ipv4 listen lines on ipv6 compile.
- Finished some of the extcmode code (memleaks).
- Fixed a problem in the new win32 resolver code
- Added HOOKTYPE_UNKUSER_QUIT (disconnects of unregistered clients).
- Fixed a Linux PPC problem (#0001242)
- Made the win32 version use libtre for regex rather than GNU regex
   libtre is smaller, faster, and more feature rich.
- Fixed some issues regarding unsetting of -R/-M when server set that mode due to a flood (+f),
   it would set the mode back immediately after next msg/join, counters are now reset.
- Updated documentation
- Added set::default-bantime. It allows you to set the default time for a gline/kline/gzline/
   shun/etc when the time is not not specified (like with /gline *@*.stupid.net).
- Added HOOKTYPE_LOCAL_PASS and HOOKTYPE_REMOTE_CONNECT
- Added HOOKTYPE_REMOTE_QUIT
- Added beta18 release notes (might be changed)
- Added HOOKTYPE_REHASHFLAG (triggered when /rehash is passed a flag)
- Fix for HOOKTYPE_REMOTE_QUIT (was called for local quits too)
- Redid the join/kick/topic hooks
- Added a few macros (MOD_HEADER, MOD_INIT, MOD_TEST, MOD_LOAD, MOD_UNLOAD) to make
   setting up a module for both static and dynamic linking easier
- Fixed a win32 resolver lockup bug
- Fixed hunt_server* bug
- Very Very small change to doc/example.conf
- Updated .CHANGES.NEW to read Beta18
- Minor doc update.
- Updated all the modules to use the new macros
- Changed version to 'beta18'
