• Bubble columns: soul sand under water lifts you up, magma pulls you down
• Fish: cod, salmon, pufferfish and tropical fish (3,000+ looks), which school, flee, flop on land and go in buckets
• Turtles: they return to their home beach to lay eggs; babies grow up dropping scutes for the turtle shell
• Dolphins: they play, escort boats, give Dolphin's Grace and lead you to treasure when fed
• Drowned and phantoms: underwater zombies that throw tridents; phantoms that hunt players who haven't slept

• Item frames on floors and ceilings, the debug stick, the furnace recipe book, the new horse model
• The /bossbar, /forceload and /data commands, and 1.13's advancements

Village & Pillage (1.14)

• 1.14's villages in place of 1.12's: plains, desert, savanna, taiga and snowy, with now and then an abandoned one overrun by zombie villagers. Other mods' village buildings still go up beside the streets
• villagers live 1.14's day. They dress for their biome, take a profession at a workstation, sleep in beds, meet at the bell, farm, gossip and breed only when there's a free bed. They trade through 1.14's trading screen, levelling from Novice to Master, with prices that follow demand and what villagers say about you. Other mods' careers keep their 1.12 trades
• iron golems guard villages 1.14's way, and curing a zombie villager makes a village like you
• the wandering trader and his llamas
• pillagers, their patrols and outposts, ravagers, and raids: walk into a village with Bad Omen and waves of raiders attack it. Defend it to become a Hero of the Village
• the crossbow, with Multishot, Piercing and Quick Charge, and firework rockets that explode on impact
• foxes, pandas, cats (ocelots can no longer be tamed, only won over), brown mooshrooms, and parrots that imitate guardians
• bamboo, bamboo jungles and scaffolding
• the new workstations: smoker, blast furnace, barrel, composter, lectern, stonecutter, grindstone, loom (with banner patterns), cartography table, fletching table and smithing table, plus recipe books for the smoker and blast furnace
• campfires, bells and lanterns
• cornflowers, lilies of the valley, wither roses and sweet berry bushes, growing wild where 1.14 grows them
• signs for every wood, dyeing sign text, the four new dyes as items, suspicious stew and leather horse armour
• banners marked on maps
• the six new note block instruments
• 1.14 sneaking: you're 1.5 blocks tall and stay crouched under low ceilings
• the /loot, /schedule and /teammsg commands, and the jigsaw block
• 1.14's path finding for every mob, including other mods' mobs
• 1.14's new advancements and its changes to old ones

A head start on later updates

• Deepslate (1.17): every variant, stairs, slabs and walls, and deepslate ores with ore dictionary entries
• Tuff, calcite and dripstone block (1.17)
• New wood sets: crimson and warped (1.16), mangrove (1.19), cherry and bamboo (1.20)
• Nether blocks (1.16): the blackstone family, basalt, quartz bricks, nether gold ore, shroomlight, soul soil and more
• Stone variants: stairs, slabs and walls for the vanilla stones, and smooth stone, sandstone and quartz
• Stripped logs, wood blocks, trapdoors, buttons and pressure plates for every vanilla wood
• Optional: give vanilla blocks and items their modern look

Built for modpacks

• Every feature can be switched off in the config, in game too
• Fish and mobs spawn in modded biomes too
• Drops are vanilla items, so other mods' recipes keep working
• Tested with Galacticraft, OptiFine and Cubic Chunks. With Cubic Chunks, everything generates across the full -64 to 320 world height
• No Mojang files inside: textures and sounds are downloaded once on first launch (internet needed that one time). On servers too

Requires

MixinBooter and AssetMover (2.5 or newer), on clients and servers.
