What's New:

User Changes:

• Added cmd:expression to /execute if.
• Updated EvalEx to v3.3.0. Release Notes...
• Removed commander:store_expression_data and commander:store_nbt_data JSON commands, as they can be easily replaced by the brigadier command and don't offer any advantages.

Example replacement:

{
  "type": "commander:store_expression_data",
  "target": "level",
  "selector": "origin",
  "key": "my_cool_data",
  "expression": "random(0, 2)"
}

Becomes:

{
  "type": "commander:commands",
  "selector": "origin",
  "commands": [
    "cmd:data write level my_cool_data ${{random(0, 2)}}"
  ]
}
