Glass

• Now acts more like most solid blocks.
  • Redstone dust and torches can now be placed on top of glass.
  • Mobs now suffocate inside glass.

Grass path, mycelium, and podzol

• Now have random orientations when placed, similar to grass blocks.

Sandstone

• Cut sandstone and cut red sandstone are now available through stonecutters.

Totems of undying

• The texture and model of the totem shown when used now has the same CustomModelData value as the item.
  • Resource packs which use this tag thus now have the correct model when activated.

Iron golems

• Tweaked spawning in villages.
  • Also only spawn now if villagers in a village have worked and slept before a meeting.

Villagers

• Improved AI.
• Baby villagers now play in villages.

Creative inventory

• Wall blocks are now found in the "Decoration Blocks" tab.

Sounds

World creation

• Worlds with names already being used now prepend a number in parentheses to the folder name instead of adding hyphens.
