Zandronum 3.0 is a major update for Zandronum that was released on 7 September 2017.


  • Updated Zandronum's (G)ZDoom base to ZDoom 2.8pre-441-g458e1b1 / GZDoom 1.8.6. [Torr Samaho]
  • Rewrote support for preferred weapon order. Weapon info is now automatically looked up, the ORDERDEF lump has been removed. [Dusk]
  • Generalized the rune system. Any rune can be used as a powerup (including spread, prosperity and reflection, which are now available as powerups), and any powerup can be used as a rune. [Dusk]
  • Added a new buffer for the reliable packets scheduled to be sent from the server to the clients. This allows to limit the number of packets the server sends to a client per tick (CVAR sv_maxpacketspertick, default 64). In particular, this allows to spread the full update a client gets when connecting to the server over multiple ticks and should fix problems connecting to large maps with many actors. Also increased the packet loss buffer size from 1024 to 2048. [Torr Samaho]
  • Added NamedRequestScriptPuke, named variant of RequestScriptPuke. The two functions can now take 1-5 parameters, thus supporting 4 script arguments. [Dusk]
  • Added ACS time and date access functions SystemTime(), GetTimeProperty and Strftime(). The return value of SystemTime() may be overridden by the user with the new CCMD acstime. [Dusk]
  • Quad-buffered stereo / 3D Vision support can now be toggled with the new CVAR gl_quadbufferedstereo (default false). [Torr Samaho]
  • The warp cheat now works online and can be used by spectators even if sv_cheats is false. [Dusk]
  • Being banned from a server now shows the server's contact email address. Being masterbanned now shows a clearer message that directs to the forums. [Dusk]
  • Players' positions in the join queue are now rendered on the scoreboard. [Dusk]
  • The internal server browser now automatically loads the wads of the selected server when joining. For this, all wads need to be in a place where they can be found with the '-file' command line option. In the browser menu, the left and right keys allow to scroll through the list of filtered servers. [Torr Samaho]
  • The 'Join the game' command key used by spectators is now customizable in the 'Customize Controls' menu. [Edward-san, Dusk]
  • The default 'authhostname' CVAR has been changed to the official zandronum game authentication server ( ). [AlexMax, Edward-san]
  • BOTINFO now allows to define more than 128 bots. [Torr Samaho]
  • Chat now features a movable cursor, allowing text insertion/deletion from elsewhere than just the end. [Dusk]
  • Chat preview is now rendered on multiple lines, if necessary. [Dusk]
  • Chat now remembers the ten previously sent messages that can be brought up with up/down arrow keys. [Dusk]
  • Chat can now tab complete player names. [Dusk]
  • Clients' account names are now visible in the output of CCMD "playerinfo", unless the player hides it with the new CVar cl_hideaccount. The server can always see the accountname from playerinfo. [Dusk]
  • Added a mechanism to safe login credentials under Windows using the Windows Credential Manager aka Windows Vault. The credentials can be stored using the new CCMD 'login_add'. A default user name can be specified with the new CVAR 'login_default_user'. [Torr Samaho]
  • This server now prevents players to use a name already used by another player. If a player requests a duplicate name, the player is renamed to 'Player N' where N is a random number from 0 to 9999. [Torr Samaho]
  • Added CCMD demo_pause that allows to pause/resume the currently played client side demo. In free spectate mode, the spectator can still move around while the demo is paused. [Torr Samaho]
  • Added cl_soundwhennotactive CVAR support to non-Windows clients. [Edward-san]
  • Added support to clientside ACS_ExecuteWithResult with four arguments. [Edward-san]
  • Added sv_survival_nomapresetondeath Zandronum dmflag to modify survival game mode where the map will not be reset on all players death - the players will be able to continue with fresh amount of lives. Dead players will carry over their inventory in accordance to "keep inventory" flags. [Zalewa]
  • Backported ZDoom's ACS function GetActorFloorTexture. [Torr Samaho]
  • The SQLite3 database can now be used in WAL mode. This mode is enabled / disabled with the new CCMDs 'db_enable_wal' / 'db_disable_wal'. [Torr Samaho]
  • Added new ACS command SetDeadSpectator (int playernumber, int deadspectator). This command can turn alive players into dead spectators (deadspectator == 1) and revive dead spectators (deadspectator == 0). [Torr Samaho]
  • Added the new ACS command SetActivatorToPlayer as a replacement solution for AAPTR_PLAYERx that works with all 64 players instead of only 8. [Dusk]
  • Added CVAR sv_forcerespawntime that controls the time delay before force respawn activates and respawns a player. [Ru5tK1ng]
  • The authentication mechanism for non-map related lumps now allows Freedoom 0.11.3/Doom clients to join Doom/Freedoom 0.11.3 servers. [Torr Samaho]

  • Changed: Spectators can now interact with gravity and use the fly/land commands. [Leonard]
  • Save games now contain information about the renderer used to create the save. This allows to print a proper error message when an incompatible save is tried to be loaded. [Torr Samaho]
  • Clients don't error out anymore when encountering a division by zero in a DECORATE expression. Instead, a one time warning is printed on the first occasion and the result is assumed to be zero. This is necessary since clients can encounter this in valid DECORATE code due to Zandronum's jump handling. [Torr Samaho]
  • Changed the dmflags values to match the ZDoom values to resolve compatibility problems with the updated ZDoom base and future ZDoom updates. Launchers and config files need to be updated to account for this change. [Torr Samaho]
  • sv_nodrop is now a dmflag. [Dusk]

  • The server now displays the IP address of the player upon connection and disconnection in log messages. [Dusk]

  • con_virtualwidth and con_virtualheight now default to 640 and 480, respectively. [Dusk]
  • kickfromgame and kickfromgame_idx have been renamed to forcespec and forcespec_idx, respectively, though the old names still exist for compatibility with e.g. aliases. Same also with the ACS function KickFromGame, whose new name is ForceToSpectate.
  • A new non-fatal 'Script Error' message will be printed if in a MAPINFO episode definition it's present either 'botskillname' or 'botskillpicname' but not 'botepisode'.
  • The CVARs gl_render_things, gl_render_walls, gl_render_flats and gl_mask_threshold are now restricted to beta builds. [Torr Samaho]
  • Make newly connected clients wait before calling a vote. The wait time is controlled with the new CVAR 'sv_voteconnectwait'. [Ru5tK1ng]
  • Keys can now be used while a client side demo is played. This allows binds to CCMDs like demo_pause to be used during playback. [Torr Samaho]
  • Dead spectators will now preserve inventory so that they can be respawned with it. [Zalewa]
  • When alive players complete the map in survival, dead spectators will recover their inventory on the next map in accordance to SV_COOP_LOSE* flags [Zalewa]
  • The 'authhostname' DNS lookup is not done during startup anymore, but only if the IP address is needed. [Torr Samaho]
  • The memory required for the bot nodes is now dynamically allocated when the first bot is added and freed when the last bot is removed. Thus, the CVAR sv_disallowbots is obsolete and was removed (adapted form Konar6's kpatch). This also fixes that offline, the memory required for the bot nodes was always allocated. [Torr Samaho]
  • To stay compatible with Zandronum 2.x, GetCVar still returns the consoleplayer's value if called in a non-player activated CLIENTSIDE script to get the value of a user cvar. [Torr Samaho]
  • Althud's discovered secret counter now shows global discovered secret count in netgames. [Zalewa]
  • Changed the default value of sv_defaultdmflags to false. [Torr Samaho]
