Changes

Set Attacker and Inflictor in usages of SWEP:FireBullets (Community Contribution)

Raise passive equipment item limit from 16 to 32 (Community Contribution)

Russian and Turkish localization updates (Community Contributions)

Prevent silly values in fog_controller (malicious map "protection"), as well as prevent map reload loop via player_loadsaved entity

Improvements to multiplayer player getters

FindEntityProcedural !pvsplayer multiplayer support improvement

UTIL_GetLocalPlayer micro optimizations

UTIL_FindClientInPVS now tries to get the closest client

Changed "exe version" to "network version" in output of "version" console command to avoid confusion

Removed newline from "Disconnect by server." kick message, so server console log is less messy. No other kick reason adds a new line at the end.

Micro optimization for GM:HUDDrawTargetID (Community Contribution)

Enable Episode 2 behavior for npc_combine_s (Some sort of "march" mode)

Allow .PCF as valid network transfer extension (FastDL)

SRCDS workshop addon cache also caches titles - Also display a warning when that cache will be used

Make "No account token specified" message in SRCDS console a warning

Unhide sv_soundscape_printdebuginfo

Reset render library's internal "last material" vartiable on map shutdown

Fallback "VertexBeckman" shader to "VertexLitGeneric" (PVK2 game)

Improve free edict detection during entity creation, so allocated edict count cannot pass the internal buffer amount and prevent creation of entities until map restart

Clean-up doubleclicking code in the main menu (Community Contribution)

Internal rework of main menu's bottom bar (Community Contribution)

Make zombies/metrocops propagate their "use lag compensation" state to spawned child NPCs (headcrabs and manhacks)

Dynamically calculate max autocomplete items for the console based on available space

Added SteamID64 to "Dropped %s player from server" console message

Enabled CEF credits button in the Options

Limit static prop counts to safe values to prevent crashes

Minor VPK support changes from CS:GO - potential memory usage improvement

Add description to g_ragdoll_maxcount convar, update descriptions for gm_snapangles and gm_snapgrid

Give prop_active_gib* convars descriptions and more sane values - 100 active gibs should be plenty (was 999999)

Add a better crash message when getting vertex size 0 to help catch source of the crash

Alias dz_door (CS:GO danger zone map doors) to prop_door_rotating

Prevent item_item_crate from spawning certain entities that could cause game crashes

Throw an engine error when trying to request invalid shader parameter, instead of cryptic crashing

Changed whereis to print path of missing files (useful for mat_texture_list 1)

Improved several console warnings and crash popups with extra information to help diagnose the underlying issues

Improved .nav file error handling to prevent game crashes and freezes, as well as error reporting

Do not save or load mat_specular/mat_bumpmap convars across game sessions - These are debugging convars, they do not need to save and cause persistent visual downgrade with no video options enabling them back.

Increase max lightmap dimensions to 128 for brushes (from 32)

Renamed npc_tf2_ghost to nb_example, and moved it from base gamemode to Sandbox

Alias sdk_lightmappedgeneric_dx9 shader to lightmappedgeneric for content from some Source Engine games/mods

Potentially improved console variable related performance

Remove main menu's reliance on RUNLUA: hack through console.log

Use consistent search paths for textures and some model code - makes textures load from consistent location of disk, just like models and materials

Make gm_spawn only work for .mdl files

Fixed crashes to do with a certain demo files that play on the wrong map (compared to the one it was recorded on)

Clear "material is missing" flag on all materials when a map is started loading

Initialize 3rd person camera on map load, to fix behavior change after first disconnect

Defer gameevent/OnRequestFullUpdate game event if not in main thread (instead of dropping it)

Reject non .vtf customization files

Optimized Sandbox Widgets system, especially when none are used on the entire server (Community Contribution)

Minor optimizations for GM:PlayerSelectSpawn (Community Contribution)

Minor loading screen cleanups (Community Contribution)

Optimized some internal engine functions to do with looping over player list, so they no longer loop over the player list

Added function locations to output of lua_find(hooks) commands and adjusted formatting and colors so its easier to read

Adjusted formatting of lua_dumptimers commands so its easier to read

Updated gmod_physiterations description to specifically mention constraints

Default presets in Utilities tab dynamically load convar defaults instead of being hardcoded

Allow fractional tickrates (i.e. 66.666), and clamp the result between 1ms and 100ms

Constraint library - Change the rope material shader blacklist to a whitelist (of UnlitGeneric, SplineRope and Cable shaders), and disallow materials that do not exist

Prevent player's view roll from being changed by bad actor maps either by spawning or teleporting the player

Add descriptions to light entity keyvalue properties in Hammer

Update StudioMDL usage info when given no parameters - added previously unmentioned command line options, dump supported .qc command list

Move modelscale keyvalue from Breakable to specifically prop_physics and its variants in Hammer to better represent what entities support the feature

Make tools/toolsinvisibleladder not create visleaves during map compilation

Adjusted VRAD's post-compile stats to show data size limits in correct places, as well as bump max data size for entity lump

Enable static prop lighting (vertex & lightmap) for VRAD with -fast (Since it is already controlled by -StaticPropLighting)

Mention -StaticPropLighting requirement for vertex lighting on static props in Hammer (Disable Vertex Lighting field)

Images are now saved as .bmp instead of .tga in HLMV

Change Shader display to a read only text entry in HLMV, so it can be copied

Display selected material in a text box in HLMV, so it can be copied

ClientsideModel is now able to be hit by clientside only traces after initializing physics on it post creation (Collision bounds must be set manually if model changes)

Try to end mesh.Begin when a mesh wasn't ended when the function is called. (i.e. after a Lua error) It will still error afterwards like it did before, but now prevents game hanging, hopefully without side effects

End current Lua mesh (if there is one) on Lua error - preventing game crashes and graphical glitches

Change ents.CreateClientRope slack parameter to work better

ents.CreateClientRope ropes now despawn if any of its attached entities are removed

Allow giving ents.CreateClientRope local vectors instead of attachment IDs

Made Entity:PhysicsInitBox/Sphere set solidity before setting the physics object - this improves behavior for those functions with ClientsideModel and is consistent with PhysicsInit()

Validate input range for File:Read and File:Write, so the game does not crash with negative bytes to read

Improved handling of BSP model names for Lua clientside entities (sets the model index so tracing code can work better)

Improved handling of infinite loops with Entity:WaterLevel when called from the water level change hook

Switch debugoverlay functions to better optional argument checking with type checking

util.IsValidModel returns false if extension is not .mdl

Changed render.DrawQuadEasy to use better optional argument handling (potentially breaking)

Sandbox gamemode: Do not store the NPCTable/VehicleTable tables on the entities (The name is still stored)

Player:GetPunchAngle will now error with lua_strict set to 1 (deprecation warning)

Allow mesh.TexCoord to only accept 1 texture coordinate

Optimizations for usage of GM:PlayerCanHearPlayersVoice - it will no longer be called for non speaking players

Minor optimizations for most Lua functions returning a sequential table

Minor adjustment to WEAPON:OnRemove for consistency of execution time with other OnRemove hooks, no functional change expected

Validate input ranges for sound.Generate (will error)

Validate input ranges for most Lua functions that use enumerations in arguments (will silently clamp the value)

Entity:GetCycle now returns 0 instead of nil for invalid entities

Prevent throwing props immediately when using +USE pickup if holding left or right mouse buttons while picking up something

Made Combine Energy Balls bounce from frozen props in a more consistent fashion

Made crossbow bolts bounce from indestructible props, frozen and unfrozen

Faceposer uses localized string for "Other" category

Minor optimizations to Problems panel, ability to close it via ESC key or clicking empty space around it (Community Contribution)

Updated browser implementation on Windows to support much newer features

"Edit Entity" window in Sandbox now shows prettier entity names (instead of the internal names) (Community Contribution)

Made r_pixelfog require sv_cheats 1 to prevent players disabling fog

Increase physgun_maxrange maximum value to 32k (from 8k)

Localize old spawnmenu category names for addon-added entities, weapons, etc (Community Contribution)

Updated Dedicated Server UI on Windows - added workshop collection entry box, gamemode selection, removed mandatory RCON password (blank=disable RCON) and replaced Steam icon with a Garry's Mod one
