For example, we could happen to have different group name rule, etc. in the future. Avoiding pointing out the latest shouldn't be too difficult .. You could just say "Please refer deployment section in Apache Avro data source guide.". if we happen to have other new changes specific to newer versions there, we should go down and fix the links in all the branches strictly in theory.
