The Minecraft JIRA (bug tracker):

New in this version:
Gameplay:
- Fixed ender pearls not teleporting logged-out users
- Fixed ender pearls forgetting their owner after reload
- Fixed steerable ridden entities teleporting back to their previous positions for a short moment on dismount
- Fixed players appearing at the initial mount location when riding a mount out of view
- Fixed horses, donkeys, mules, and boats sometimes disappearing after dismounting
- Fixed ending up on top of boats when exiting
- Fixed boats breaking lily pads creating too many particles
- Fixed extreme lag spikes when pillagers are loaded
- Fixed pillagers not despawning
- Fixed raid horn sounds playing globally in all villages

Technical:
- Fixed disabling fire damage not disabling magma block damage
- Loot table predicates can now be defined in separate files
- /execute if predicate - New subcommand evaluates custom predicates (defined in predicates directory of datapack)
- predicate= selector argument
- reference condition in loot tables to apply an externally defined predicate
- /schedule ... [append|replace] (/schedule ... defaults to replace)
- /schedule clear (id) to remove existing schedules (returns number of removed schedules)
- /kill now defaults to @s if no target argument is given
- Entity loot table predicate now accepts player field, which checks player properties. Fails when entity is not player.
- level: range of allowed player levels
- gamemode: same values as /gamemode command
- stats: list of statistics to match
- Entry fields: type (like minecraft:custom), stat (like minecraft:sneak_time) and value (int range)
- recipes: map of recipe ids - Boolean value tells if it should or should not be known to player
- advancements: map of advancement ids
- If value is boolean, checks if advancement is done. If value is object, checks completion of criterions.
- Entity predicate now accepts team field, which matches team name
- Location predicate
- Also accepts block and fluid sub-predicate. Available fields:
- block/fluid: exact block/fluid id to match
- tag: block/fluid tag to match
- nbt: matcher for block entity NBT (only for blocks)
- state: map of name-value properties
- Value can be integer, boolean or string or object with optional min and max properties
- Now accepts light sub-predicate
- Object has one integer range - light that matches visible light (max(sky-darkening,block))
- location_check: new parameters added: offsetX, offsetY, offsetZ - optional offsets to location
- time_check: new condition that checks day time
- value: range of accepted values
- period: if present, time will be modulo-divided by this value (for example, if set to 24000, value will operate on time of day)
- Data commands can now use storage as target - a general-purpose key-value storage
- Storage is shared between all dimensions in level
- Data in storage persists between reloads
- Blaze3d refactorings
