Server owners please update your servers! Disclaimer: Due to major changes to the .cfg files be sure to update them to your needs, such as setting server name, global/local stats, etc... Plus more convars have been listed in server_core.cfg. If you want to enable arena hardmode or hard scaling for Objective/Story/Arena, be sure to set this as well @ server_core.cfg! We've also updated the default mapcycle for dedicated servers, it no longer contains any Deathmatch or Elimination maps by default, if you still want to host DM or Elimination, add the respective maps to the mapcycle!

Code

• Major optimization for client & server, went through roughly all the code, cleaned up messy code, fixed null pointer bugs, fixed overly expensive code, etc...
• Added full client-side playermodel support similar to Sven Co-Op and GoldSrc in general, meaning you can play as any survivor model, anyone who also has that survivor model will be able to see you, otherwise it uses a default. (survivor models are defined in the character scripts)
• Improved lag compensation and hit detection, especially for melee weapons.
• Dev, Donator, Tester and other data tags should work properly again.
• Reduced memory usage and removed some unnecessary hl2 content files.
• LOCAL STATS CAN NOW BE USED IN A LISTENSERVER FOR OFFLINE PLAY!
• Fixed a major bug in the local stats, when I implemented Zombie skills saving I forgot to increase the buffer for saving the local stats to a file, so basically it wouldn't save everything!
• Local Stats will no longer be disabled if sv_cheats is 1.
• Default tickrate for dedicated servers has been lowered from 66 to 33, you can still use a higher tickrate by simply passing the -tickrate XX param to the srcds application.
• Reloading server data or client data will now dispatch an event so that we can update accordingly, for instance the NPCs will now properly fixup the data pointers when reloading data, otherwise you'd risk invalid pointers!
• Increased bb2_high_ping_limit to 350 from 250.
• Updated server_core.cfg to include a bunch of new useful convars, take a look!
• Updated the game icon for hl2.exe @ Windows only.
• Updated the game's music folder, there might be some missing music in some of the maps, if you get any FMOD errors please let us know!
• It is no longer possible to evade bans or kicks, plus if you get kicked you'll be banned for roughly 5 minutes to prevent people from simply rejoining and repeating. The ban on kick can be administered with the bb2_vote_kick_ban_time command.
• Removed Elimination & Deathmatch maps from the standard dedicated server mapcycle file, if you still want to host Elimination or Deathmatch maps feel free to re-add them to your mapcycle!
• Soundscapes should work properly for dedicated servers running under Linux.
• Updated to the latest SDK2013 binaries.

• Increased gib limit from 128 to 256!
• When new gibs spawn and you reach the gib limit, old gibs will fade out instead of fading the new gibs out quickly.
• Fixed a terribly sad bug which prevented the fantastic blood cloud from appearing properly when smashing zombies to bits.
• Players should now emit the right blood decals depending on your bb2_extreme_gore value.
• Blood particles & decals will no longer spawn when attacking friendly npcs when the round hadn't started, when zombies fade-in or when a player has spawn protection active.
• Buckshot damage should now properly spawn blood decals & particles.

• XP received when completing quests & objectives have been reduced to 4% for quests and 2% for objectives. Previously you'd receive 10% for quests and 5% for objectives which was far TOO much.
• XP received when finishing a round in Arena, an entire game in Arena or an entire game in Objective will now give you percentage based XP increase instead of a small fixed number!
• Added bb2_story_dynamic_respawn for Story mode, which allows players to respawn where the action's at rather than at the same checkpoints all the time.
• When a new round has begun you'll not be able to create a vote for roughly 60 sec. The delay can be administered with bb2_vote_roundstart_delay.
• Added bb2_arena_hard_mode which will disable reinforcements in Arena mode, you'll however receive more XP. In order to activate this you have to set bb2_arena_hard_mode to 1 then change map to any Arena map. You cannot disable/enable this while in the map due to exploiting.
• Added bb2_hard_scaling which enables a new scaling technique for Arena, Objective & Story mode, it relies on the average level of the players which is a good way to make the game more challenging depending on the average level in the game. Set bb2_hard_scaling to 1 and change map to enable it properly.

• Optimized NPC netcode, reduced bitstream by 80 bits for all NPCs and 323 bits for all zombie NPCs!
• Fixed a bug which would force NPC ragdolls to always fade out after roughly 4 seconds regardless of your bb2_gibs_fadeout_time value. (NPC gibs were not affected)
• Fixed a potential bug that could break any objective or arena map if you were using entity counting via logic_entity_counter or logic_objective/logic_quest, if an NPC killed a boss and bb2_allow_npc_to_score was set to 0, the kill would not be registered!
• Frag grenades should now properly notify all NPCs of danger.
• NPCs can now be given random health, random damage values, random kick values and random speed values!
• Removed glow logic from npcs, meaning you can no longer make npcs use the glow outline effect.
• Reduced zombie lifespan to 18-36 sec, previously it was 30-90. Plus reduced boundaries on the convar min and max values.
• Zombie Walkers & Runners will have their lifespan refreshed whenever they take damage from human players.
• Fixed a random bug which could make a zombie gib itself when dying due to the lifespan feature, if the zombie was previously hit in a hitgroup which allowed gibbing.
• Bandit NPCs should no longer T-pose randomly. (hopefully...)
• Health and Damage scaling for the npc_custom_actor will now update properly on spawn and when players connect/disconnect.
• Fixed Fred's bounding box so that he can get through tinier doorways.
• Fred will now do an inverse-shockwave special attack targeting players that are camping, a random player which is at least 100 units above Fred will be selected, that player and nearby players will be pulled towards Fred with zero-G force!
• Improved door breaking for all zombie NPCs.
• Improved AI responsiveness and efficiency.
• npc_m1a1 now supports disabling collision.
• Simplified Walker & Runner spawning, Runners would sometimes bug when trying to play the 'rise' schedule.
• Zombies will no longer try to break obstructions that are either above or underneath them...

• smart_trigger will now check for default filters and such before checking the new built-in filtering, plus the other outputs will be fired properly. Previously this trigger only fired OnTouching.
• Removed constraint flag for items and weapons, items and weapons in BB2 don't use physics unless dropped anyway.
• You can now set the interruptibility choice for the npc_auto_spawner and zombie_volume auto-schedule on spawn feature.
• zombie_volume now allows you to set how near a player has to be before it starts spawning, you can also set the spawn frequency, you can choose to skip visibility checks, set the desired max Z-difference between the trigger and player.
• zombie_volume will now check if any player is inside its volume before making other complex checks, if true it'll spawn right away.
• Added a new handy texture proxy 'TeamLinkTexture' which can be used to only allow a certain team to see a certain texture.
• Player and Zombie spawn points now have a 'Master' option, enabling this will make the spawn act as a last resort, meaning you can spawn in it even if it is disabled, if no other checkpoint was found.
• Tweaked the inventory system, you can now set the spawn angle for items, change their scale and set the entity link through the item/map script.
• Teleporting an inventory item will properly update the origin of its objective icon, if any.
• Fixed a bug which prevented you from changing the glow mode of an entity if it was set to radius glow on spawn.
• Human & Zombie spawn points will be properly reset on game restart.
• zombie_volume will use a smaller hull for zombies that are fading in. Allowing more zombies to spawn in the volume.

• Steam Avatars should load more effectively.
• The leaderboard panel will now display how many entries were found.
• Fixed a bug which would break parts of the Graphics Options on OSX & Linux, most of the options would only be rendered as (*).
• Fixed minor bugs in the page handling in the leaderboard panel and map selection panel.
• Leaderboards will no longer update continuously as long as you're in-game, this would sometimes create unexpected lag and stuttering due to the high upload rate, from now on you only update your leaderboard entry when you disconnect from a game.

• You can no longer activate zombie rage or other human perks when the end scores are visible / voting screen.

• Increased propane velocity on throw by 200 units.
• Reverted to the old Sawed-Off where you have to press LMB for barrel 1 and RMB for barrel 2.
