The underlying GNU/Linux operating system was upgraded. This release is based on the Ubuntu Quantal repository (as of 2012/Nov/26).
Package drbl was updated to 2.1.34-drbl1, and clonezilla was updated to 3.1.22-drbl1. The new paths for the files in these two packages are in /usr/sbin, /usr/bin, /usr/share/drbl/sbin, and /usr/share/drbl/bin. No more under /opt/drbl/. Hence, the new pre-run and post-run paths are /usr/share/drbl/prerun/ocs/ and /usr/share/drbl/postrun/ocs/, respectively.
A KMS mode was added in the boot menu.
Partclone was updated to 0.2.56.
Packages tcplay and mpg123 were added.
Boot parameter "ocs_lang" is now replaced by "locales" from live-config.
Boot parameter "ocs_live_keymap" is now replaced by "keyboard-layouts" from live-config.
Boot parameters "echo_ocs_prerun" and "echo_ocs_postrun" were added. This can be used to disable echoing the ocs_prerun and ocs_postrun command.
An option to use "autohostname" to create the image name was added. Thanks to tererecool (David Bauer) for this idea.
The command to save an image will be saved in the image dir as file Info-saved-by-cmd.txt.
Another partition table file, e.g. sda-pt.parted.compact, will be saved in image dir when saving an image. It's easier for human to read.

A better mechanism was implemented to decide the restored OS is using grub 1 or 2. Thanks to Robert Weir for reporting this issue on Fedora 17 restoring.
The *.mod files for grub2 are not fixed in the path /boot/grub/. It could be in /boot/grub/i386-pc/. Function install_grub_hd failed in this case.
Program ocs-lvm2-stop did not work on Ubuntu Linux due to the udevd rules 85-lvm2.rules from Ubuntu.
The function install_grub_hd in ocs-live-dev should skip checking the boot loader on the USB flash drive, because it might be new, empty one.
To avoid the KMS and vmwgfx conflict issue (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686939), some blacklist boot parameters were added.
The VOL_LIMIT for splitting image file could not larger than 20000000000000. Ref: https://sourceforge.net/tracker/?func=detail&atid=671650&aid=3567350&group_id=115473
Saving mode should enable ncurse interface by default, too. Otherwise it's confusing.
Program run-parts is confusing, there now we use drbl-run-parts.
The description using space key to mark the selection for disk to disk clone is not required. Thanks to sabrehagen (https://sourceforge.net/tracker/?func=detail&atid=671650&aid=3552271&group_id=115473).
