Yeah, there's no official position on this. BTW see the new home of what info is published on this topic: http://spark.apache.org/versioning-policy.html
The answer is indeed that minor releases have a target cadence, but maintenance releases are as-needed, as defined by the release manager's judgment. From https://issues.apache.org/jira/browse/SPARK/?selectedTab=com.atlassian.jira.jira-projects-plugin:versions-panel you can see that maintenance releases for a minor release seem to continue for 3-6 months in general, with 1.6.x going on for a longer period as the last 1.x minor release. I wouldn't mind putting down some text to set a non-binding expectation around this, that minor releases might be 'supported' for 3-6 months? until 2 more minor releases have succeeded it? Because in practice that's very much how back-ports behave. We also don't say anything about major releases but I think that may also be too rare to put even informal statements around. Every couple years?
