Minecraft:Old Growth Spruce Taiga and Minecraft:Old Growth Pine Taiga
- Increased the size of the Minecraft:podzol patches generated beneath mega pines and mega Minecraft:spruces.

- Seagrass no longer pokes through Minecraft:ice when it generates in shallow Minecraft:water in biomes that have ice on the water's surface.
Technical
Minecraft:Add-Ons and Script Engine
- Custom biome names are no longer implied by their filenames. Biome names are explicitly specified via the Template:Cd property under the Template:Cd sub-object of their JSON definition.
- Biome identifiers must now be namespaced (ex: Template:Cd). Client biomes with a format version lower than 1.21.90 will have their identifier automatically prefixed Template:Cd when loaded if no namespace is already specified.
- Updated biome documentation to match updated biome JSON formatting and requirements.
- The Template:Cd parameter of the Template:Cd method on Template:Cd no longer accepts a Template:Cd as an option. This option was redundant as it is covered by the existing Template:Cd option. This affects the Template:Cd method in all versions.
- Updated many error strings to use consistent punctuation.
- The properties Template:Cd and Template:Cd on the Template:Cd class are now optional.
- Updated several APIs to throw Template:Cd instead of Template:Cd where appropriate. This affects the following APIs in all versions:
- Template:Cd for when the Template:Cd setting is out of bounds (0 - 255) or Template:Cd setting is out of bounds (1 - 20000000).
- Template:Cd for when the Template:Cd parameter is out of bounds (-1000 - 1000 per axis).
- Template:Cd and Template:Cd for when the Template:Cd parameter is out of bounds (0 - 100 max lines, 0 - 1000 max length per line).
- Template:Cd and Template:Cd for when the Template:Cd parameter is out of bounds (0 - 255).
- Some existing errors that throw Template:Cd have been updated to use a standardized error message. This affects the following APIs in all versions:
- Template:Cd for when the Template:Cd, Template:Cd or Template:Cd settings are out of bounds (min value of 0).
- Template:Cd for when the Template:Cd setting is out of bounds (0 - 1).
- Template:Cd for when the Template:Cd setting is out of bounds (10 - 90) or Template:Cd setting is out of bounds (1 - 16).
- Template:Cd and Template:Cd for when the Template:Cd parameter length is out of bounds (0 - 255).
- Some existing errors that throw Template:Cd have been updated to use a standardized error message.
- Template:Cd for when the Template:Cd parameter is empty or a duplicate.
- Released Template:Cd to Template:Cd.
Block Components
- Modified Template:Cd block component.
- Field Template:Cd no longer requires "Upcoming Creator Features" experiment to work, Json Template:Cd still needs to be >= Template:Cd.
Components

- Content warnings will log missing references in Template:Cd JSON.
- The Template:Cd component has been renamed to Template:Cd.
Entity Components

Graphical

- Added Template:Cd and Template:Cd rules to jigsaw processors.
- Added heightmap projection type Template:Cd and made it the default setting, which instead of performing heightmap calculations uses the starting placement position.
