v3.0.0

3.0.0 (2026-02-25)

• feat!: remove console output and exitOnError, return warnings from loadExtended (282f32a), closes #77 #78

Bug Fixes

• normalize type coercion across all types (b4df29f), closes #76
• report clear errors for null values in config files (a9669ba), closes #75
• resolve all lint errors in test files (8fbba15)

BREAKING CHANGES

• loadExtended() now returns { data, warnings } instead of
  a raw NodeTree. The exitOnError option has been removed — errors always
  throw ConfigLoadError. The library no longer calls console.warn,
  console.error, or process.exit. Warnings are accessible via
  loadExtended().warnings or ConfigLoadError.warnings.
