v0.41.0...v0.42.0

v0.41.0

Breaking

• XO can no longer be installed globally.
  • It caused too many problems. Instead, you can run the local XO binary with $ npx xo.
• XO now enforces trailing comma in multiline statements.
  • This has a lot of benefits.
  • Prettier also enforces this by default.
  • If you don't want it, you can disable the comma-dangle rule, and @typescript-eslint/comma-dangle if you use TypeScript.
• Change operator-linebreak rule to enforce operators before.
  • This way is more readable.
