Minecraft 26.3 Pre-Release 1

The first pre-release for 26.3 is here! There are technical changes, but we are now mainly fixing bugs, making improvements and putting on the final touches ahead of release.

Happy mining!

Changes#

UI#

• On macOS, Exclusive Fullscreen is now available again
• On macOS, added a "Menu/Dock Visibility" option in Video Settings, which controls whether the macOS Menu bar and Dock can be revealed by moving the mouse to the edge of the screen while in fullscreen
• The cursor is now confined to the window while Exclusive Fullscreen is active

Technical Changes#

• The Data Pack version is now 119.0
• The Resource Pack version is now 97.1

Data Pack Version 119.0#

• The minecraft:number_provider and minecraft:number_provider_type registries have been split into separate registries for integer calculations (minecraft:context_int_provider, minecraft:context_int_provider_type) and float calculations (minecraft:context_float_provider, )

Number Providers#

Number provider types and values have been split into two separate registries: minecraft:context_int_provider and minecraft:context_float_provider to avoid accidental loss of precision and range due to mixing of float and integer operations

Note: those new types should not be confused with already existing minecraft:int_provider_type and minecraft:float_provider_type, which are context-free providers, used mostly for world generation

Following number provider types have been split into integer and float variants:

• minecraft:constant
• minecraft:uniform
• minecraft:storage
• minecraft:sum (renamed to minecraft:add)
• (renamed to )

Following number providers types are now only available in integer variant:

• minecraft:binomial
• minecraft:score

Following number providers types are now only available in float variant:

• minecraft:enchantment_level

Following vanilla number providers have been migrated to minecraft:context_int_provider registry:

• minecraft:compostable/low
• minecraft:compostable/low_medium
• minecraft:compostable/medium
• minecraft:compostable/medium_high
• minecraft:compostable/always_add_one

Following vanilla number providers have been migrated to minecraft:context_float_provider registry:

• minecraft:cooking/speed_default
• minecraft:cooking/normal_speed_multiplier
• minecraft:cooking/fast_speed_multiplier
• minecraft:brewing/speed_default

Following vanilla number providers have been removed:
