- Issues
- fix: preserve distinct inherited validation constraints
- fix(Length): pick the violated bound when each: true
- fix: @Length with each: true on string[] reports wrong constraint in error message
- fix: `arrayUnique` is O(nĀ²) and reports any array containing `NaN` as non-unique
- perf: improve ArrayUnique lookup performance
- fix(Length): don't reference unset constraint in error message
- feat: add IsMutuallyExclusiveWith decorator
- Security hardening: validateSync/validate inspect the live object ā read-unstable properties (getters/Proxy) can bypass validation
- fix: `getTargetValidationMetadatas` scans every registered class on each validation (O(N)), dominating CPU in large apps
- fix: reject enum member names in @IsEnum for numeric enums
