Fixed

• Fixed TypeScript type inference for discriminated unions in ValidationErrors. #653
• Fixed FormData parsing for discriminated unions, so they work properly without requiring dataType: 'json'. #655
• reset() function didn't preserve tainted state for fields that are not being reset when using partial data. #656
• Fixed FormData parsing incorrectly coercing empty strings to literal values (e.g., z.literal("bar")). Empty strings now properly fail validation instead of being replaced with the literal value. #664
• Fixed ReferenceError when using customValidity with validateForm({ update: true }). #669

Changed

• Replaced deprecated @finom/zod-to-json-schema with zod-v3-to-json-schema. #660
• Migrated Valibot adapter to use the official @valibot/to-json-schema package. #668
