New features

guestfish

   - guestfish strings can use escapes,
     eg. ><fs> write /foo "line 1\nline 2\n"
   - guestfish write-append command can be used to append to files.
   - Long-running file uploads and downloads can be cancelled through the
     API or by hitting ^C in guestfish.
   - New guestfish "display" command for displaying graphical files
     inside guests.
   - In guestfish, tab completion now works on /dev/mapper devices.

virt-inspector

   - Inspection API can get an icon or logo for certain guests.
   - virt-inspector includes the logo and hostname for certain guests.
   - virt-inspector can now get the version and release numbers for RPM
     packages.
   - CentOS and Scientific Linux are now treated as separate distros by
     the inspection API.

virt-resize

   - virt-resize can now handle btrfs.
   - New virt-resize --ntfsresize-force option allows Windows VMs to be
     resized multiple times.

other virt tools

   - guestfish, guestmount, virt-cat, virt-df, virt-edit, virt-filesystems,
     virt-inspector, virt-ls and virt-rescue now allow you to use
     "-d UUID" option to specify a guest by UUID.  This makes them more
     robust to use from other programs.
   - virt-ls -lR option allows complex file iteration and guest analysis.
   - virt-win-reg supports HKEY_USERS\<SID> and HKEY_USERS\<username>.
   - virt-win-reg new option --unsafe-printable-strings allows printable
     strings to be displayed in the output (unsafely: read the documentation
     before using).
   - virt-edit has been rewritten in C.

API and language bindings

   - Java is now completely supported.
     See http://libguestfs.org/guestfs-java.3.html
   - JRuby is supported via the Java bindings.
   - guestfs_close now appears in trace messages.
   - Python binding adds explicit g.close() method.
   - Python programs can now use the new event API.
   - Python GIL is released during libguestfs calls, allowing multithreaded
     Python programs to work properly.
   - 9pfs (Plan 9 filesystems exported from the host) are now supported.
   - Add -DGUESTFS_WARN_DEPRECATED=1 to warn about use of deprecated API
     functions in C programs.
   - New manual page guestfs-recipes(1) with recipes.
   - mkfs-opts can now set inode size and sector size on created filesystems
     (thanks Nikita Menkovich).
   - guestfs_last_errno is now accessible from OCaml (as g#last_errno ()).

Security

 - optargs_bitmask is checked even for calls that have no optional
   arguments.  This closes a possible exploit in the daemon from
   untrusted callers.

New APIs

  btrfs-filesystem-resize, get-pgroup, inspect-get-icon, is-zero,
  is-zero-device, list-9p, list-dm-devices, mount-9p, ntfsresize-opts,
  set-pgroup, write-append

Internals

 - Coverity (a static analysis tool) was run across the codebase and
   many fixes were made.
 - Generator can handle functions that return RBufferOut and have
   optional arguments.
 - Compatible with Perl 5.14.
 - Compatible with gcc 4.6.
 - Perform safety checks on QEMU.
 - C API tests can now fully test calls that have optional arguments.
 - Use ./configure --enable-install-daemon to install /usr/sbin/guestfsd.
 - po-docs directory now covers all man pages.
 - stderr from qemu process is now captured by the event subsystem.
