ocaml-augeas 0.7 was released today: https://download.libguestfs.org/ocaml-augeas/

One change that affects libguestfs is that Augeas.matches returns matches in the correct order, instead of in reverse order as before. That could affect how libguestfs inspects disks and how virt-v2v does conversions (although I tested it and I couldn't find anything obvious). http://git.annexia.org/?p=ocaml-augeas.git;a=commitdiff;h=b703b92e3d26690aa6f7b822132049ce5435983e
