Upstream GlusterFS could do with a decent feature matrix on the website, to show which GlusterFS features are introduced in which versions. The upstream PostgreSQL website has a good example we could follow: http://www.postgresql.org/about/featurematrix/
Eco Willson might be the right guy to do this. BZ won't let me assign this to him though (yet). :(
pre-release version is ambiguous and about to be removed as a choice. If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
