Even though the current stable branch is 1.4.x[1] I'm not going to leave the 1.2.x branch to completely wither. I will still pull in any more serious bug fixes into the 1.2.x branch and make an occasional release. Therefore I have released 1.4.1 and 1.2.10 which contain a small number of bug fixes. If you are using earlier 1.4.x or 1.2.x versions, and if you simply want a more stable version of libguestfs with no surprises, then upgrading along the same branch is recommended. I still get reports from people using the old 1.0.x versions, and I would *strongly* recommend upgrading to at least 1.2.10 as nearly 100 bugs have been fixed. This link shows the changes along the stable-1.2 branch: http://git.annexia.org/?p=libguestfs.git;a=shortlog;h=refs/heads/stable-1.2 and this link shows the same for the stable-1.4 branch: http://git.annexia.org/?p=libguestfs.git;a=shortlog;h=refs/heads/stable-1.4 The upstream branches currently map to Fedora, RHEL and EPEL releases as follows: Rawhide 1.5.x (currently 1.5.0) Fedora 13 1.4.x (currently 1.4.1) Fedora 12 1.2.x (currently 1.2.10) EPEL 5 1.2.x (currently 1.2.10) RHEL 6.0 1.2.7 + backported fixes and features needed for V2V RHEL 6.1 undecided, probably rebase to latest 1.2.x or 1.4.x RHEL 5.5 with RHEV-M subscription 1.2.7 + backported fixes and features needed for V2V Link to latest public builds: http://koji.fedoraproject.org/koji/packageinfo?packageID=8391 Rich.
