Additions

General

Game rule

Added the tntExplodes game rule.
- When false, TNT will not explode and cannot be primed by any means.
  - Trying to do so directly, like with a flint and steel, will show a message on the action bar.
  - Powering a TNT block with redstone makes it simply vanish, as does blowing it up with a creeper.
  - A TNT block on fire can burn up as if it was a plank.
- Default value: true

Tag

Added #flowers item tag.
- Corresponds to the #flowers block tag.

Changes

Blocks

Cactus Flower

Can now be placed on farmland.
Can now be picked up and carried by endermen.

Test Block and Test Instance Block

Their textures have been updated.

Mobs

Cow

The new models have been tweaked so the horn placement and leg positioning now match the model on Bedrock Edition.
The textures of temperate cow legs no longer have harsh borders due to a mirroring issue.
The heads of baby cows are now positioned correctly.

Sheep

Its wool texture has been tweaked to remove the stark line at the back.

General

Data pack

The pack format version is now 70.

Entity data

Custom data (previously present only on markers) is now available on all entities.
- It is exposed as a minecraft:custom_data component, so it can be set by spawning items and matched by predicates.
- The component is currently stored in a field called data.
- It is stored only if it's non-empty.

Predicates

Block predicates
- New optional fields have been added to block predicates: components and predicates.
- Their functionality and format are identical to the fields components and predicates on item predicates, but they operate on block entity components (when present).
  - When present, components will match exact contents of block entity components.
  - When present, predicates will match partial contents of block entity components.

Entity predicates
- A new optional field has been added to entity predicates: predicates.
  - Its functionality and format is identical to the field predicates on item predicates, but they operate on entity components.
    - When present, predicates will match partial contents of entity components.

Resource pack

The version is now 54.
"Global" uniforms may now be defined in any shader, and the game will attempt to fill it.
- Currently, these are: ModelViewMat, ProjMat, TextureMat, ScreenSize, ColorModulator, Light0_Direction, Light1_Direction, GlintAlpha, FogStart, FogEnd, FogColor, FogShape, LineWidth, GameTime, ModelOffset.
- The type of the uniform must match what it would normally be, or it'll be undefined behavior.

SNBT format

SNBT now also supports following operations:
- bool(arg) - converts argument to boolean.
  - If argument is a boolean value, returns value directly.
  - If argument is a number value, returns true if it is non-zero.
- uuid(str) - converts string representation of UUID to integer array.
Implicit infinite float values (like 1e1000) are now rejected.

Sounds

Blocks that are broken by a piston now play their breaking sound.

Tag

Added cactus_flower to #enderman_holdable block tag.
Removed blocks that mine instantly without a tool from the #mineable/axe, and #sword_efficient block tags.

Title screen

The panorama was changed to showcase the Spring to Life.
