# 6.4.0

### What's new

- New `ClassAnonymizationSettings` for custom anonymization per country, region, and document type
- Added `isFilledByDomainKnowledge` property to `DateResult` and `Date`, indicating the date is filled from internal document knowledge rather than extracted from the image
- Added missing mandatory field feedback during scanning with the BlinkID overlay
- Added `cardRotation` result member to `ImageAnalysisResult`

### Breaking API changes

- `StringResult`: String values for each document field and alphabet are now accessed directly via `latin`, `arabic`, and `cyrillic` members
- `BlinkIdMultiSideRecognizerResult`: `dataMatchResult` renamed to `dataMatch`
