Non-command Minecraft 1.13 news: https://www.youtube.com/watch?v=6uWV1zEPml0

General:
- New command parser: Brigadier
- Now only have SuccessCount + Result, Command blocks output Result

Functions:
- Parsed on load, in data packs
- Can be grouped in tags
- /function #(namespace):tag runs all functions in a tag
- gameLoopFunction game rule removed
- #minecraft:tick runs every tick
- #minecraft:load runs on data pack (re-)load

Coordinates:
- Local coordinates specified as ^left ^up ^forwards

Selectors:
- Numeric matching ranges: min..max
- Decimal support
- Renames: c - limit, m - gamemode, lm & l - level, - r & rm -- distance, rx & rxm - x_rotation, ry & rym - y_rotation
- Can quote string arguments
- sort: nearest, furthest, random, arbitrary
- scores={obj=range,obj2=range2,...}
- advancements={foo=true,custom:something={criterion=true}}
- nbt={nbt}
- Can use multiple arguments where it makes sense
- @r is now only players
- @a, @e default sort now arbitrary

Blocks:
- Block specifiers can always include block states, nbt
- minecraft:block_name[state=true,another=2]{NbtField:{Blah:1s}}
- Can match block tag, #(namespace):(tag)

Items:
- Item specifiers can always include nbt
- minecraft:item_name{NbtField:1s}
- Can match item tag, #(namespace):(tag)

Contexts and /execute:
- /execute (specifier chain) run (command)
- Direct upgrade: /execute as (target) at @s positioned (x y z) run (command)

Context manipulation:
- as (target)
- at (target)
- positioned (xyz)
- positioned as (target)
- align (axes)
- rotated (y x)
- rotated as (target)
- facing (xyz)
- facing entity (target) (anchor)
- in (dimension)
- anchored (feet|eyes)

Conditionals:
- if|unless block (xyz) (block)
- if|unless blocks (begin) (end) (destination) (all|masked)
- if|unless entity (target)
- if|unless score (target) (targetObjective) (operator) (source) (sourceObjective)
- if|unless score (target) (objective) matches (range)
- Conditionals used without a run specifier acts as their own commands, return match number

Result management:
- store (result|success) score (name) (objective)
- store (result|success) block (xyz) (path) (type) (scale)
- store (result|success) entity (target) (path) (type) (scale)
- type: byte|double|float|int|long|short
- Paths: [] for array access, . for member access, "" to quote field names
- store (result|success) bossbar (id) (value|max)

Scoreboards:
- New subcommand: /scoreboard players get (target) (objective)
- Objective names are now text components
- /scoreboard objectives modify (objective) rendertype (integer|hearts)
- /tag, /team split out
- prefix, suffix fields are now text components

Teleportation:
- /tp & /teleport now aliases
- /teleport (entity)
- /teleport (xyz)
- /teleport (victim) (entity)
- /teleport (victim) (xyz) [yRot xRot]
- /teleport (victim) (xyz) facing [xyz]
- /teleport (victim) (xyz) facing entity (target) [feet|eyes]
- Teleporting to another dimension now allowed

XP:
- /xp & /experience now aliases
- /experience add (target) (amount) [points|levels] - default points
- /experience set (target) (amount) [points|levels]
- /experience query (target) (points|levels)

New commands:
- /data merge block (xyz) (nbt)
- /data merge entity (target) (nbt)
- /data get block (xyz) [path] [scale]
- /data get entity (target) [path] [scale]
- /data remove block (xyz) (path)
- /data remove entity (target) (path)

- /bossbar create (id) (name) - name is a text component
- /bossbar set (id) (option) (value) - name, color, style, value, max, visible, players
- /bossbar remove (id)
- /bossbar list
- /bossbar get (id) max|players|value|visible
