I've been ranting about this on Twitter for a while, and now blogged about it:http://people.planetpostgresql.org/devrim/index.php?/archives/89-9.6,-or-10.0.html There are major changes in 9.6 (some of them are listed in the blog post), and I think they are good enough to call this 10.0. A counter argument might be waiting for pglogical for inclusion, but I think the current changes are enough to warrant a .0 release.
