Question

In 1.18.1 is the mob generation different for my mob farms? Like different from 1.16 and 1.18

Answer 1

Apparently, no.

According to 1.18.1 Minecraft changelog, changes were applied to fog:

World fog now starts further away from the player, to make distant terrain more visible.
Instead of applying fog as a spherical volume, it is now applied as a cylindrical volume.

And of course, several bugs were fixed. But nothing regarding mob spawn.

Latest version to change mobs spawn was 1.18:

• Axolotls can now only spawn in the water above clay blocks in lush cave biomes.
• Cod, dolphins, pufferfish, salmon, squid, and tropical fish will only spawn in water between height levels Y=50 and Y=64. However, these creatures can spawn in lush cave biomes' water at any height.
• Drowned zombies can now spawn in dripstone cave biomes and warm ocean biomes.
• Pillagers can now spawn on snow blocks.
• Foxes can now spawn on podzol, snow, and coarse dirt blocks.
• Glow squids now only spawn in water blocks under the height level Y=30.
• Goats may now only spawn in snowy slope, jagged peaks, and snowy peak mountain biomes.
• Rabbits can now spawn on snow blocks.
• Wolves can now spawn on snow blocks.
• Hostile mobs now spawn only in areas where the block light level is equal to zero.
