• Material reading fixes
• engine.CloseServer no longer falsely claims the server is shutting down
• file.Read blocklist updated so it doesn't affect file and folder names in the DATA path
• Added 9 new Combine related props; combine_booth_tall01b.vmt made less extremely glossy
• Fixed a missing material on a CS:S prop and an EP1 prop

• Block envmap and lightprobe commands from Lua
• Replace usages of string.Explode with string.Split
• Properly fix env_microphone missing closed captions
• Dedicated server workshop cleanup now runs in the correct folder (it was cleaning cache/workshop/ while files were saved to cache/srcds/)
• Fixed some dupes/saves/demos not loading when they only have a single tag (Dupe, Save or Demo)
• More decompression self checks; the FastLZ fallback was removed from util.Decompress (workshop dupes/saves already use LZMA, util.Compress has used LZMA since 2014)

• Enable ALT+F4 closing the game
• Get/SetNetworkAngles exist serverside for consistency, and check for reasonable values
• Apply "that getmetatable() LuaJIT fix someone wanted"
• Handle context menu errors when the "originator" panel is removed
• Fixed engine.LightStyle only updating static props once (community contribution)
• Removed non-functional map compile tool parameters (-novconfig, -vproject, -x360/-nox360, -xbox, VBSP -virtualdispphysics); -tmpout moved from VVIS to VBSP; some undocumented VBSP params documented
• Added -noTJuncsDetail to VBSP from TF2
• Applied the T-junction limit softcap (community contribution) so the compiler no longer just stops
• MAX_MAP_TEXINFO bumped to the new TF2 limit (16k → 32k)
• Removed redundant VRAD code, fixed VRAD potentially adding new planes; VBSP detail sprite limit raised (2 million → 2 billion)
• r_DrawBeams 2 now affects sprite trails (wireframe)

• surface.DrawPoly throws an error on invalid data (fewer than 3 verts)
• Ropes no longer go invisible with r_queued_ropes 0; mat_queue_mode 2; gmod_mcore_test 1
• sk_auto_reload_time works again; it requires gmod_suit 1, and a value of 0 or below disables the feature

Full change list:

• Fixed Spawnmenu middle mouse click regression
• Handle addons not providing complete data for NPC weapons, so the spawnmenu doesn't get bricked entirely
• Fixed -force32bit trying to launch 64-bit CEF
• Use more dynamic fallback for Infected shader: instead of shipping edited materials, it is done in code
• Fix false positive with "Out of bounds bone in CIKContext"
• Fixed potential npc_alyx related crashes
• Potential fix for a crash on "that one CS:S map"
• Update Windows symstore path
