v2.2.0

Minor Changes

• 65d468e: Add Zod 4 compatibility and improve JavaScript builtin handling

  • FEAT: Update import generation to use zod/v4 for Zod 4 compatibility
  • FEAT: Add support for new Zod 4 object methods (.strict() → z.strictObject(), .passthrough() → z.looseObject())
  • FIX: Significantly improve JavaScript builtin detection to prevent incorrect transformations
  • REFACTOR: Replace brittle regex-based post-processing with robust AST-based transformations
  • IMPROVEMENT: Enhanced context-aware detection between runtypes schema usage and JavaScript builtin usage

  This update ensures that:

  • Boolean(), String(), Number(), Symbol() calls remain as JavaScript built-ins
  • .filter(Boolean) stays as native Boolean instead of being transformed to z.boolean()
  • Only actual runtypes imports get transformed to their Zod equivalents
  • Generated code uses Zod 4 API patterns for future compatibility
