Release candidate 2 for 3.6.0. Single tuning fix on top of rc1: at low zoom (z3-5) wind streamlines compounded into a uniform grey band along the wind direction, obscuring the basemap. No code-path changes — pure visual tuning, no impact on any other feature.
What's new in rc2 (since rc1)
Low-zoom streamline tuning
Four-part fix using z7 as the visual reference (z7+ unchanged):
- Trail decay sharpened. Fade now targets ~0.5% alpha by particle-lifetime end (was 5%) so trails crisp-end instead of asymptote-linger. Lifetime cap dropped from 600 frames (20 s) to 120 frames (4 s).
- Per-stroke alpha attenuated at low zoom. New
globalAlpha = pow(detailMultiplier, 1/3)cube-root scaling: full at z12+, ~0.45 at z3. - Density additionally tapered below z7. Linear ramp from 0.5× at z3 to 1.0× at z7, on top of the existing detail multiplier.
- Line width inverse-scaled at low zoom. Strokes are 3 px at z3 → 1 px at z7+, compensating visually for the lower density.
Cumulative effect at z3: ~50% the particle count, each rendered at 3 px width and ~45% opacity, with trails that crisply fade to invisible by 4 seconds. At z7+, behaviour is identical to rc1.
Diagnosed by attaching to a live HA testbed via the Chrome DevTools Protocol — the same workflow that unblocked the rc1 streak-layering fix.
Cumulative since 3.5.0
Same as rc1 plus the low-zoom tuning above. See v3.6.0-rc1 notes for the full 3.6 feature inventory.
Upgrade notes
No breaking changes. No new config keys. Existing 3.5.x and 3.6.0-rc1 configs continue to work unchanged. Pure visual refinement of the existing wind streamline overlay.
