  Slipstream Jetstream 1.5.0.7 -- jetstream-1.5.0.7 (1b7f54e358).

  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 jetstream-1.5.0.6.

  Fixes

  • #1008: rigged RT cadence only for no-self-shadow avatars (fixes the self-shadow flicker); off when none is traced (3348272b4f)

  Other changes

  • #1003: particle fog UI -- on by default, density 10, quality preset, Photo Studio section (1b7f54e358)
  • #1003: particle fog -- shape separate from opacity (cloud mask from relative density x base lumps; core density inside) (96998974f2)
  • #1003: billowing particle fog -- erosion noise, lumpy puffs, self-shadowed local lights, AO, HG halos, heavy settling, sharper near fog (eb116459f9)
  • #1003: particle fog texture test -- only hard edges mark a shaped texture; glowy fog at full score (eeaa8e5b1b)
  • #1003: particle fog classifier -- SRC_ALPHA,ONE glowy fog converts, short smoke puffs and rising smoke no longer rejected (5c8ba91126)
  • #1003: debug log keyed by the emitter's source id (U32) (2ea9c1dcf3)
  • #1003: particle fog debug log -- each system's inputs and the rule that kept it a particle (RenderVKParticleFogDebug) (3f58f3c0e4)
  • #1015: RT no longer hard-capped at a percentage of VRAM; avatars leave RT shadows only under real VRAM pressure (b8ff5d39ff)
  • #1003: particle fog classifier read ordinary systems as additive; fullbright no longer excludes (6f9180f8b9)
  • #1003: particle fog -- fog-like particle systems become dense local volumetric fog (RenderVKParticleFog, default off) (ce08e12284)
  • #1012: weather beds -- two cross-fading playheads, sparse-bed drop layer, slow level drift (WeatherAudioLoopVariation) (0ca8251156)
  • #1011: ranked shared cut -- per-instance completeness marker in mode 11 (an unskinned entry: no derived / shared cut for that instance) (96423eee4d)
  • #1011: Cluster LOD RT -- profile sub-marks, ranked shared cut (no mode-11 gather, stable slots, parallel admit), rigged CLAS reuse on the shared skinning (87b0288f16)
  • #1010: gather instance-cap warning states the real effect; arena-full WARN only at the limit (growth = INFO) (577ab3f3ab)
  • #1010: cluster LOD skinned arena -- VRAM-derived limit, whole-avatar coarsening, never a partial avatar (2fbd39c3d6)
  • #1009: Cluster LOD -- cluster-traced statics emit again in the emissive light build (legacy row beside the cluster RT row) (22c43ab86c)
  • #1008: rigged cluster RT cadence default off (flickering self-shadow on avatars and animesh) (e31d965457)
  • #1006: emissive light build -- incremental cell rebuild (dirty cells, budget, forward map), origin shift, weak-emitter overlay (bf965f49fd)
  • #1008: cluster RT -- rigged RT cut decoupled from the raster cut (bands, cadence, coarser mid / far cuts, pose-delta CLAS rebuilds) (d451a121fc)
  • #1007: rigged BLAS refit -- distance-band cadence + pose skip on near-unchanged poses (bd1911891f)
  • #1008: GPU timer mark after the async RT build join (g_join_rt_build) (4792318bd7)
  • RT signals under DLSS: stop forcing full resolution by default; the user's scale settings apply (2baa8e9a2a)
  • #978: GI phase 2 -- one-frame-latency GI: the trace runs on its own async segment after the combine (RenderVKGILatencyFrame) (d75c207bb2)
  • RT reflections: GPU hang (Xid 109) -- every ray query gets valid input; the back-face re-trace no longer steps tmin past tmax (ab53e12cc9)
  • #1001: undo 'Pause mine while it's worn' for scripted AOs (Resume button, Forget list, detect-off stops deferring) (78f95d91e4)
