"The latest version of System Rescue version 1.1.5 is
out today and it includes a few notable improvements over its
predecessors. The most important in my view is support for the ext4
Linux filesystem. Version 1.1.5 includes a new Linux kernel with
support for ext4 as well as including a version 0.4.2 of the
GParted partitioning software that includes support for
ext4."
