Commit bb557c on main ports a fix for math.ceil/math.floor, adds self checks for corrupted map files and stops the load command from booting you out of the session when the save is missing.

In #next-update, Vitroze reported that PANEL:OnMousePressed now always calling MouseCapture breaks VGUI addons such as GmodAdminSuite. Rubat called it an issue with the mod but asked for a repro. Commit bb557c fixed the regression and Vitroze thanked him.

NovaDiablox asked to unbind F8 by default. robotboy655 declined: loading shouldn't boot you from the session; the engine wrongly checked mountable games for the "quick" save file. Commit bb557c fixes it.

Akabenko wrote on his request to add the 3D skybox to SSAO_DepthPass that a stencil is needed, because the game world is expected to always render on top of the 3D skybox.

Earu reported that a brush model with an $alphatest material leaks render state, so materials without $basetexture (vgui/white, surface.DrawRect, fonts) stop rendering. He provided a map for robotboy655; the issue was closed as completed the same day.

In #developer-talk, Nak released a NikNaks version with BSP physics parsing (not on the Workshop yet). Later he said BSP parsing is up to ~2x faster, BitBuffer 2–3x and mesh generation 3–5x.

drobotk's PR makes ENT:StoreOutput treat times=0 like times=-1, matching engine entities. Merged on 15 October (commit bb557c).

In #next-update, Earu asked why fading static props stop writing depth while they fade out. Artemking4 and Evgeny Akabenko explained that fading props are moved to the translucent pass, and translucent objects don't write depth. In the evening discussion, Rubat asked why transparent props would write depth at all, and said alpha testing is irrelevant for fadeouts. Earu said he would remove his issue. Evgeny Akabenko and Earu then discussed dithered fades combined with TAA.
