Commit bb0975 on the x86-64 beta brings over the main changes from 5–12 October: the surface.DrawPoly error on fewer than 3 vertices, the mcore rope fix, ALT+F4 closing the game, the getmetatable() LuaJIT fix, the map compiler updates, Entity:SetPos running trigger touch events, menu state library removal, the HQ Eli face and the other fixes listed in commits 185851, efb205, 7be067, 71ca28, c18cba and 693484.

In #developer-talk, nighty said the main branch uses LuaJIT 2.0.4 and the x86-64 beta uses LuaJIT 2.1 beta 3. Zaurzo added that 64-bit main uses the same LuaJIT as x86-64. nighty described his lua_shared fork: it targets a custom language but should run existing GMod Lua exactly like stock, and isn't public yet. Its threading is worker-based, with message passing between separate Lua states. He also showed Jolt physics experiments.

Commit 79007f on main gets Bootil, FreeImage, SQLite and LuaJIT building for Linux64 and fixes Linux builds broken by Awesomium ("Can't get rid of it soon enough").

In #next-update, RaphaelIT7 asked whether "Apply that getmetatable() LuaJIT fix someone wanted" was ported to x86-64: his crashes were gone on dev but not on x86-64. Rubat: "if it isn't in the changelog, stands to reason it wasn't yet".

In #developer-talk, Nak showed his LuaOS running DOOM at decent resolution with sound. A JIT-friendly self-patching block cache took it from 0.9M to 8M instructions per second; later a GTA beta loaded.

Commit efb205 on main enables ALT+F4 to close the game, makes Entity:Get/SetNetworkAngles exist serverside, applies the requested getmetatable() LuaJIT fix and brings several map compiler limits and fixes over from TF2.
