Lighting reworked: sky light takes the color of the sky (blue day, warm sunset, grey rain, blue moonlight); torch light no longer counted twice and fades smoothly over all 15 light levels.
Glow: separate emission buffer blurred into a colored halo (Glow screen in settings).
Redstone glow, plus furnaces, candles, crystals, sculk, portal, ores, glowing mobs, eyes, beacon beams, particles, held items.
Held light: a torch in hand lights the area around you.
Glow rebuilt: emission blurred with a real Gaussian at 8 sizes (new composite1 pass), summed into a bright core with a long soft tail. No squares, no flicker.
Redstone glow: one clean red.
Rain: wet reflective ground, puddles with raindrop rings, denser ripples on water.

First public release.

Deferred lighting with PCSS soft shadows, colored torch light and emissive blocks.
Water: waves, refraction, screen-space reflections, foam, caustics, Snell’s window, underwater god rays.
Volumetric clouds with cloud shadows, volumetric light, ground fog, aurora.
Round phased moon, softer realistic rain.
Bloom, auto exposure, lens flare, color grading, vignette.
