Hi!

The Linux-v3.7 is out, and it's good time to release the next version
of the checkpoint-restore tool.

This is mostly bugfix and improvements release, however it's worth
mentioning some new interesting features

  * Proper COW mappings handling
    Now anonymous private mappings are not COW-ed at restore, but
    pages that were shared remain such [1]

  * Full support for PF_PACKET sockets, thus letting us to C/R the
    tcpdump tool

  * The --shell-job option, which makes it possible to dump apps
    launched from one shell and restore them in another [2]

Some features are still available with the custom kernel, but things
are eventually getting merged upstream. In particular the 3.7 now has
support for C/R-ing of LXC containers' network devices, the initial
support for packet sockets and a couple of fixes for TCP repair code.


The v0.3 can be downloaded from
