New features

• New utility functions in @rjsf/utils used by the validators and core

@rjsf/antd

• Treat multiple as a boolean rather than comparing against undefined in the SelectWidget, fixing #3595

@rjsf/core

• Switched Form to use the new validatorDataMerge() and toErrorList() functions instead of the now deprecated schemaUtils.mergeValidatorData() and schemaUtils.getValidator().toErrorList()
• Added option to provide a callback function to focusOnFirstError (3590)
• Updated MultiSchemaField to handle the OpenAPI discriminator extension on anyOf/oneOf fields by passing it into getClosestMatchingOption() if it exists, fixing #3512
• Updated SchemaField function to use getSchemaType rather than schema.type to set the proper class name.

@rjsf/utils

• Refactored the createErrorHandler(), toErrorList(), toErrorSchema() and unwrapErrorHandler() functions from the @rjsf/validator-ajv6 and @rjsf/validator-ajv8 implementations since they were identical
  • As a result, the mergeValidationData() function was deprecated in favor of the new validationDataMerge() function that uses the refactored toErrorList() function
  • Refactored the ROOT_SCHEMA_PREFIX constant as well
• Updated ValidatorType and SchemaUtilsType to deprecate the toErrorList() and mergeValidationData() functions, respectively
• Updated the getClosestMatchingOption() and getFirstMatchingOption() to pass the new discriminatorField to the getMatchingOption() function
• Updated getMatchingOption() to use discriminatorField when it is present in the options object properties to drill into the object to detect if that one field is valid
• Updated SchemaUtilsType and the associated forward functions in createSchemaUtils to add the new discriminatorField?: string optional parameter
• Updated toIdSchema() function to use getSchemaType(schema) === 'object' rather than schema.type === 'object' to get the proper pathing for ids, fixing #2044

@rjsf/validator-ajv6

• Removed the refactored functions and constant from the AJV6Validator in favor of using the new functions and constant from @rjsf/utils

@rjsf/validator-ajv8

• Removed the refactored functions and constant from the AJV8Validator in favor of using the new functions and constant from @rjsf/utils

Dev / docs / playground

• Updated the utility-functions documentation to describe the new refactored functions as well as deprecating the mergeValidationData() function
• Updated the playground to properly restore liveSettings from shared links and added a switch for noHtml5Validation in the live settings rather than having it set to true always
  • Also added a new Blank example to help users easily paste their code
