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
