Slowlight

Waystones and Nightfall.

Waystones

• Pair two Waystones with a Twin Pearl, then send a stack from one to the other. Each trip burns a Chorus Pearl and takes days to arrive.
• Some things change on the way: glass sent to the End comes out as Starglass, candles from the Nether become Starwick Candles, stained glass sent to the Nether becomes Nether glass, and more. JEI lists every route.
• Unfalling Feather: carry it and you drift down instead of falling.
• Wandering Apple: eat it and you come straight up to the open sky.
• New blocks: Display Pedestal, Pearl Lantern, Pearl Chain, Block of Chorus Pearl, Hollowstone, Starglass, and crimson, warped, soul and magma glass in three patterns each.

Nightfall

• Cheese Wheel: milk left a week in a dark cellar. Set it down and eat it a wedge at a time.
• Some recipes now want a full moon, a new moon, a cold biome or a dark cellar. Drinks age quicker in a cellar.
• Moondial: under open sky, a comparator reads the moon's phase off it.
• Letter to Later: seal a signed book with honeycomb for 1 to 365 days. It won't open before then.
• Moths round the Slowlight Lantern and ripe Lanternfruit, four new stats and two new advancements.

Also

• Preserves come in round jars with cloth caps.
• The Sandglass tumbles over when it turns.
• The Gloamwood button gives a 1-tick pulse and can be pressed again straight away.
