Version 1.12-1 of ddrescue has been uploaded.

http://www.gnu.org/software/ddrescue/ddrescue.html

Description from README:
GNU ddrescue is a data recovery tool. It copies data from one file or
block device (hard disc, cdrom, etc) to another, trying hard to rescue
data in case of read errors.

The basic operation of ddrescue is fully automatic. That is, you don't
have to wait for an error, stop the program, read the log, run it in
reverse mode, etc.

If you use the logfile feature of ddrescue, the data is rescued very
efficiently, (only the needed blocks are read). Also you can interrupt
the rescue at any time and resume it later at the same point.

Ddrescue is also able to selectively overwrite parts of the output file,
which has a number of interesting uses like wiping data, marking bad
areas or even, in some cases, "repair" damaged sectors.

Upstream NEWS:

Changes in version 1.10:

The new option "--try-again" has been added.

The size skipped when bad sectors are found has been made independent of
"cluster-size".

Rescue speed has been improved for large logfiles.

An overflow reading from devices of undefined size has been fixed.

Changes in version 1.11:

In case of error writing the logfile to disc, the user is now given the
possibility of fixing the problem and continue.

The splitting algorithm has been modified to read sequentially the areas
smaller than a threshold size.

After every read error, ddrescue now verifies the input file has not
disappeared.

In rescue mode, ddrescue now shows the time elapsed from the last
successful read.

Signals SIGUSR1 and SIGUSR2 are now ignored by ddrescue.

Descriptions of "--direct", "--synchronous" and "--sparse" in the manual
have been made clearer.

Description of rescue algorithm in the manual has been made clearer.

"make check" now verifies that files are open in binary mode.

A warning about logfile usage has been added to "ddrescue --help" output.

Changes in version 1.12:

The destination file is now created with write permission for all if
umask allows it.

Files are now open in binary mode in non-POSIX platforms defining the
O_BINARY macro.

Lintian warnings in Debian about man pages have been fixed.
