I am pleased to announce the release of GNU ddrescue 1.29.1.

GNU ddrescue is a data recovery tool. It copies data from one file or block 
device to another, trying to rescue the good parts first in case of read 
errors. Ddrescue recommends lziprecover, whose data recovery capabilities 
complement those of ddrescue.

The ddrescue package also includes ddrescuelog, an auxiliary tool that 
manipulates ddrescue mapfiles, shows mapfile contents, converts mapfiles 
to/from other formats, compares mapfiles, tests rescue status, and can 
delete a mapfile if the rescue is done.

The homepage is at http://www.gnu.org/software/ddrescue/ddrescue.html

The sources can be downloaded from http://ftpmirror.gnu.org/ddrescue/ 
http://download.savannah.gnu.org/releases/ddrescue/ or from your favorite 
GNU mirror.

This release is also GPG signed. You can download the signature by appending 
'.sig' to the URL. If the 'gpg --verify' command fails because you don't 
have the required public key, then run this command to import it:

   gpg --recv-keys 8FE99503132D7742

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742


Changes in version 1.29.1:

   * The new option '--bad-sector-data=<file>' has been added. It makes 
ddrescue treat as a read error any sector containing the same data as 
<file>. This is useful when the drive, instead of signaling a read error, 
returns known garbage data (different for each drive model). If you need to 
use this option, it means that the failing drive lacks adequate integrity 
checking. (Suggested by Eliyahu Saks).

   * It has been documented in the manual the way of extending outfile to 
the size of the partition when using option '--domain-mapfile'. (Reported by 
Bret Quigley II).
