1.1     ! root        1: Changes for 3.17
        !             2: ----------------
        !             3: 
        !             4: - added sanity checks before calling atan2 with divisors of 0.  This was
        !             5:   accidentally working on Intel chips, but caused crashes on DEC Alpha AXP
        !             6:   port.
        !             7: - updated QUAKE2.DSW and QUAKE2.DSP file to support DEC Alpha
        !             8: - Autodownloading is now DISABLED by DEFAULT.  It must be enabled by typing
        !             9:   'allow_download 1' at the console, or using the download options menu
        !            10:   in Multiplayer/PlayerSetup/Download Options
        !            11: - Server demos now include a svc_serverdata block at the beginning with the
        !            12:   attractloop byte set to '2' to indicate server demo (byte before gamedir
        !            13:   in the svc_serverdata block).  This allows easy identification of
        !            14:   serverrecorded demos (serverrecord demos are only for demo editors, they
        !            15:   can not be played back in Quake2 without being first edited).
        !            16: - New options for setting texture formats in ref_gl:
        !            17:   gl_texturealphamode:  default, GL_RGBA, GL_RGBA8, GL_RGB5_A1, GL_RGBA4, 
        !            18:     GL_RGBA2
        !            19:   gl_texturesolidmode:  default, GL_RGB, GL_RGB8, GL_RGB5, GL_RGB4,
        !            20:     GL_R3_G3_B2, GL_RGB2 (SGI only)
        !            21: - Player movement during Air acceleration changed to reflect more real-world 
        !            22:   physics while airborne.
        !            23: - Fixed a bug when riding trains that caused drift in a southwest direction
        !            24:   (Thanks to Jim Dose at Ritual for pointing this one out).
        !            25: - Linux:  Now correctly reports out of memory rather than segfaulting (mmap
        !            26:   returns (void *)-1 and not NULL on error).
        !            27: - Fixed autodownloading to not create paths for files that can't be downloaded
        !            28:   (this was creating many empty directories in baseq2/players).
        !            29: - When downloading a file from a server that doesn't have it, the message is
        !            30:   now "Server does not have this file" rather than "File not found."
        !            31: - Fixed some coop keys in 3.15 weren't being handled correctly (pyramid key).
        !            32: - Highbits are now stripped from console when using condump
        !            33: - Restored support for gl_modulate in multiplayer play
        !            34: - Fixed it so that players with a model/skin you don't have aren't checked for 
        !            35:   on disk more than once.
        !            36: - Fixed it so sounds played for PPMs that default to male are only checked
        !            37:   on disk once.
        !            38: - Byte ordering/portability fixes in cinematics, PCX and other file handling.
        !            39: - Client state during static image cinematic (PCX image) so that client can 
        !            40:   continue to next unit.
        !            41: - Fixed it so that dedicated coop servers no longer get stuck at victory.pcx,
        !            42:   if a server is in coop mode, hitting a button at the victory.pcx screen
        !            43:   while cause the server to restart at base1
        !            44: - Fixed infinite grenade bug
        !            45: - Fixed autodownloading to actually download sounds and console pics
        !            46: - Fixed autodownload to not create empty directories for files not on
        !            47:   the server.
        !            48: - Added customized client downloading.  cvars are the same as the server side:
        !            49:     allow_download - global download on/off
        !            50:     allow_download_players - players download on/off
        !            51:     allow_download_models - models download on/off
        !            52:     allow_download_sounds - sounds download on/off
        !            53:     allow_download_maps - maps download on/off
        !            54:   They can also be (more easily) set with a new Download Options menu 
        !            55:   accessible in Multiplayer/Player Setup/Download Options
        !            56: - Changed checksumming code to be more portable and faster.
        !            57:   The checksum in 3.15 was seriously broken.
        !            58:   This change makes 3.17 incompatible with previous servers.
        !            59: - Fixed player 'warping' present in 3.15 (this was an artifact of the
        !            60:   hyperblaster optimizations).
        !            61: - Fixed the autodownload in 3.15 so that stuff like skins for models are
        !            62:   downloaded as well as pics.
        !            63: 
        !            64: Changes for 3.15
        !            65: ----------------
        !            66: 
        !            67: - Added visible weapons support.  This is precached with a special symbol, i.e.
        !            68:   gi.modelindex("#w_shotgun.md2") which causes the client to autobind it to
        !            69:   the players current weapon model.  Plug in player models can optionally 
        !            70:   support the visible weapons.  Any that do not support it will use their
        !            71:   default weapon.md2 files automatically.
        !            72:   Visible weapons files for plug in player models are not downloaded
        !            73:   automatically--only the default weapon.md2 (and skin) is.
        !            74:   The Visible weapon models themselves are not included.  They can be
        !            75:   downloaded from http://www.telefragged.com/vwep/
        !            76: - Rewrote the some of the net code to use optimized network packets for 
        !            77:   projectiles.  This is transparent to the game code, but improves netplay
        !            78:   substancially.  The hyperblaster doesn't flood modem players anymore.
        !            79: - Rewrote the packet checksum code to be more portable and defeat proxy bots
        !            80:   yet again.
        !            81: - Autodownload support is in.  The following items will be automatcally
        !            82:   downloaded as needed:
        !            83:     - world map (and textures)
        !            84:     - models
        !            85:     - sounds (precached ones)
        !            86:     - plug in player model, skin, skin_i and weapon.md2
        !            87:   downloads go to a temp file (maps/blah.tmp for example) and get renamed
        !            88:   when done.  autoresume is supported (if you lose connect during the
        !            89:   download, just reconnect and resume).  Server has fine control over
        !            90:   the downloads with the following new cvars:
        !            91:     allow_download - global download on/off
        !            92:     allow_download_players - players download on/off
        !            93:     allow_download_models - models download on/off
        !            94:     allow_download_sounds - sounds download on/off
        !            95:     allow_download_maps - maps download on/off
        !            96:   maps that are in pak files will _not_ autodownload from the server, this
        !            97:   is for copyright considerations.
        !            98:   The QuakeWorld bug of the server map changing while download a map has
        !            99:   been fixed.
        !           100: - New option in the Multiplayer/Player Setup menu for setting your connection
        !           101:   speed.  This sets a default rate for the player and can improve net
        !           102:   performance for modem connections.
        !           103: - Rewrote some of the save game code to make it more portable.  I wanted to
        !           104:   completely rewrite the entire save game system and make it portable across
        !           105:   versions and operating systems, but this would require an enormous amount
        !           106:   of work.
        !           107: - Added another 512 configure strings for general usage for mod makers.
        !           108:   This gives lots of room for general string displays on the HUD and in other
        !           109:   data.
        !           110: - Player movement code re-written to be similiar to that of NetQuake and
        !           111:   later versions of QuakeWorld.  Player has more control in the air and
        !           112:   gets a boost in vertical speed when jumping off the top of ramps.
        !           113: - Fixed up serverrecord so that it works correctly with the later versions.
        !           114:   serverrecord lets the server do a recording of the current game that
        !           115:   demo editors can use to make demos from any PVS in the level.  Server
        !           116:   recorded demos are BIG.  Will look at using delta compression in them
        !           117:   to cut down the size.
        !           118: - Copy protection CD check has been removed.
        !           119: - Quake2 3.15 has changed the protocol (so old servers will not run) but
        !           120:   all existing game dlls can run on the new version (albiet without the
        !           121:   new features such as visible weapons).
        !           122: - Added flood protection.  Controlled from the following cvars:
        !           123:    flood_msgs - maximum number of messages allowed in the time period
        !           124:                 specified by flood_persecond
        !           125:    flood_persecond - time period that a maximum of flood_msgs messages are
        !           126:                      permitted
        !           127:    flood_waitdelay - amount of time a client gets muzzled for flooding
        !           128:   (gamex86 DLL specific)
        !           129: - fixed it so blaster/hyperblaster shots aren't treated as solid when
        !           130:   predicting--you aren't clipped against them now.
        !           131:   (gamex86 DLL specific, the SVF_DEADMONSTER flag is set on projectiles)
        !           132: - gender support is now in.  The userinfo cvar "gender" can be set to
        !           133:   male/female/none (none for neutral messages).  This doesn't affect sounds
        !           134:   but does affect death messages in the game.  The models male and cyborg
        !           135:   default to gender male, and female and crackhor default to female.
        !           136:   Everything else defaults to none, but you can set it by typing
        !           137:   "gender male" or "gender female" as appropriate.
        !           138: - IP banning support ala QW.  It's built into the game dll as 'sv' console
        !           139:   commands.  This list is:
        !           140:     sv addip <ip-mask>  - adds an ip to the ban list
        !           141:        sv listip <ip-mask> - removes an ip from the ban list
        !           142:        sv writeip - writes the ban list to <gamedir>/listip.cfg.  You can
        !           143:          exec this on a server load to load the list on subsequent server runs.
        !           144:          like so:  quake2 +set dedicated 1 +exec listip.cfg
        !           145:        sv removeip <ip-mask> - remove an ip from the list
        !           146:   the ip list is a simple mask system.  Adding 192.168 to the list
        !           147:   would block out everyone in the 192.168.*.* net block.  You get 1024 bans,
        !           148:   if you need more, recompile the game dll. :)
        !           149:   A new cvar is also supported called 'filterban'.  It defaults to one which
        !           150:   means "allow everyone to connect _except_ those matching in the ban list."
        !           151:   If you set it to zero, the meaning reverses like so, "don't allow anyone
        !           152:   to connect unless they are in the list."
        !           153:   (gamex86 DLL specific)
        !           154:
