We decided a while back to not continue doing releases for HBase-1.0, so please don't push to or recreate the 4.x-HBase-1.0 branch.
Also, looks like the current release of HBase 1.3 branch has some blockers for Phoenix, so we'll need to wait until the next HBase 1.3 branch to start doing Phoenix releases that support it. I've removed the 4.x-HBase-1.3 branch for now to avoid any confusion. Thanks, James
