The dev discussion appears to be going that direction. We already have version numbers on the data encoding format (javabin, xml, etc.), we may need it for the content of the request as well. See the newly added comments on SOLR-5762: https://issues.apache.org/jira/browse/SOLR-5762?focusedCommentId=13920560&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13920560 Thanks, Shawn
