I think this list doesn't include the ones where just the type changed. If I remember correctly aws sdk used to emit all request type attributes by default and response ones only with the experimental flag.
aws.dynamodb.table_names type change from string -> string[]
experimental aws.dynamodb.consumed_capacity type change from string -> string[]
aws.dynamodb.global_secondary_indexes type change from string -> string[]
aws.dynamodb.local_secondary_indexes type change from string -> string[]
aws.dynamodb.consistent_read type change from string -> boolean
aws.dynamodb.table_count type change from string -> long
aws.dynamodb.limit type change from string -> long
aws.dynamodb.attributes_to_get type change from string -> string[]
aws.dynamodb.segment type change from string -> long
aws.dynamodb.total_segments type change from string -> long
experimental aws.dynamodb.count type change from string -> long
experimental aws.dynamodb.scanned_count type change from string -> long
