    Slipstream Beta 1.4.0.2 -- v1.4.0-beta.2 (af5af782eb).

    Linux x86_64 (glibc >= 2.38, x86-64-v2 CPU): *_x86_64.tar.xz
    Ubuntu 24.04+ / Debian 13+ / Mint 22+: *_amd64.deb (sudo apt install ./)
    Windows x64 (unsigned; SmartScreen: More info > Run anyway): *_Setup.exe installer, or *_win64.zip to unpack anywhere

    Changes since v1.4.0-beta.1.

    New features

    • #783: snow rests on VERTICAL column tops -- the weather maps render untilted while snow falls or lies, and the fall direction only shapes where snow lands (an oblique heightfield march in the snow kernels), not the support (6ad2524599)

    Fixes

    • #783: M3 fixes: the rigged VS's avatar-slot load only while avatars carry snow; stamp-head WAW barrier; world streams back after the cascades' snow draw (bbe0c5fae6)
    • #876: crash reports name the pipeline the crashing compile thread was compiling; 'far' is a Windows macro (slweather.cpp) (a40b676002)

    Other changes

    • Weather sounds: ship the CC0 pack from app_settings/sounds/weather in the repo (af5af782eb)
    • VK VRAM: never re-allocate probes/shadows at the OOM wall (NVIDIA segfault in vkAllocateMemory) (90a1de69ef)
    • Weather floater: include roles_constants.h for GP_LAND_CHANGE_IDENTITY (ed9c2c6d68)
    • Weather (#783): export local weather to the parcel description tag (eb31c1fc91)
    • Weather: drop the 'only you see it' wording from the floater and toolbar tooltip (6c8b554201)
    • #783: the cover (coating) on a sheltered top is capped at its share of the open sky's -- a lee formed after the coating fell melts back, as the depth's level does (be7977a5ea)
    • #783: snow drift walls / view-dependent ring + dither / tints -- the wind takes only a loose surface layer and never blows snow above its source's top, the repose is an avalanche (not frame-time scaled), the weather maps centre on the ground under the camera, mesh vertices stored bit-exact (2643718efb)
    • #882: Build > Texture Media subtab -- lay its children out with explicit top/left/width instead of right=-4 / bottom=-8 edge anchors (they resolved against an unsized panel and landed outside the subtab) (7ce059eae8)
    • #783: outer ring -- planRing drops its dead inputs; memory notes match (2 MB ring vertices, 19 MB mesh, the ring allocated with the snow even when off) (0c35a23dbe)
    • #783: snow outer ring -- a coarser depth grid on the coarse map's plane (same filtered-base model, stepped every few frames), inner grid authoritative with a two-way hand-off, and world-space LOD bands (geomorph + complementary dither crossfade, ring fade to the coating, stride morphs) instead of the grid-space fade that jumped with every snap (97041aa044)
    • #783: snow repose relaxation mirrors a neighbour past the grid's border from the opposite one (a slope no longer depletes / piles the border rows a snap then carries inward); a fifth of the donor per neighbour at most (no overdraw with drift) (3d4aff1635)
    • #783: snow on a filtered base -- the column tops closed then opened (R 2 texels) in the cover kernel; depth, transport, footprints and the mesh use it; one snow-top connectivity rule; repose relaxation replaces settle / slide; thin-top / base-step / taper heuristics removed (fc3c2441fd)
    • #783: snow spikes -- no banking toward a higher neighbour (it left a one-texel ridge along every bridged seam: pyramids on a diagonal one); only a drop ends a thin run (a top is thin, the ground between pickets / under a rail is not) (0d177c5a52)
    • #783: snow spikes -- one slope-limited same-surface rule (a few cm + tan 40 x distance, texel by texel); thin tops (1-3 texels) carry no depth and no sheet; transport never settles / drifts across steep steps; spike clamp on every snow top (985d97362e)
    • #853: report tracker -- closed reports never notify, only a newer human comment or a reopen does (high-water id/time, count display-only), no polling before login, one popup per poll (e1b3f0e3b6)
    • #783: snow mesh banks the lower side of a bridged step (no averaging: the higher side never thins, the slant clears the step's edge); the drift inflow past the grid border takes the texel's fill, not the global depth (no border ridge for a snap to carry inward) (dcf33263cb)
    • #783: snow seams + snow mesh edges -- the grid border no longer thins the depth (seam grid after snaps); the mesh tapers to the ground, bridges small steps, skirts real cuts, marching-squares outlines (23c34028c0)
    • #874: RT audit -- cluster AS storage rows are 'unverifiable', not bad; freed-after-build is bad only while the frame may still have run (787ead1c34)
    • #874: DEVICE_LOST RT scene audit -- host readback of the TLAS records + rt_geom, every BLAS reference / CPU table / fault address checked against the address registry (efbca8be93)
    • #783: M3 snow shader docs: name the module constants, not settings that do not exist (comment only; SPIR-V unchanged) (e59b31a440)
    • #783: M3 renderer: the snow surface mesh in the deferred G-buffer and the sun cascades (a0a88b8049)
    • #783: M3 weather module: depth / transport push, avatar pass + footprints, snow mesh build in prepare() (a78e94f6ef)
    • #783: M3 shaders: snow depth field + drift / slide / settle, avatars' own snow + footprints, the snow surface mesh (3e5700d753)
    • #783: M3 state: the global snow depth (metres; intensity x duration, melts with the cover) + the M3 settings (224f6b558e)
    • #783: snow patches and puddles from rotated gradient-noise octaves (value noise showed its square lattice) (1add7c0672)
    • #783: snow beyond the cover grid (the grid lookup zeroed the global cover on a miss); unpublish the grid when RenderVKWeatherSnowCover is off (a90db82e0f)
    • #783: M2 movers' snow: the FS never fetches past the per-instance image (rows in ssr.weather[11].x) (0ea4abf212)
    • #783: M2 weather module docs: per-recording steps, memory / cost, probes and mirrors draw no precipitation (f364c17eb2)
    • #783: M2 rain splashes (93456ae1e0)
    • #783: M2 snow cover: a risen column top starts at the open-sky cover, not bare (e3c99b22c8)

    • Default LimitSelectDistance off: select / edit objects at any distance (d298b19643)
    • #783: lightning counts as visible weather (storm flashes draw with no precipitation) (e61133f2f5)
    • #783: thunder fixups: pack check for storm-only weather, a decode slot of its own, storm gate settles exactly (e647e586fa)
    • #783: M2 puddle / wet-ground reflections ride the existing SSR + RT hybrid path (e9a94fc16c)
    • #783: Weather floater: wind variation / gustiness, thunderstorm, region weather opt-ins with status (deaeb4a342)

    • #783: M2 lightning visuals and weather cloud cover (773508b8ea)
    • #783: M2 wind-tilted roof map: sheared ortho cascades along the mean fall direction, wind-facing walls wet (1919c265b0)
    • #783: weather audio: thunder per strike (delayed, positioned, sheltered, occluded), gusty wind beds, close-strike ducking (eae31a4160)
    • #783: M2 weather state: seeded gusts (windMean = eased mean, wind = gusty) and deterministic lightning strikes (58bb28eb81)
    • #783: llaudio: local shots (positioned one-shot PCM, EFX low-pass + room send) for thunder (6f70d7a513)

    • #783: weather audio: drain drips only with a live cover answer (9c374a6014)
    • #783: weather audio: ignore roof material shares under 10% (no bed loaded for a stray ray) (2df668b4d8)
    • #783: About: courtesy credit for the Freesound authors of the weather sounds (CC0) (69432a7128)
