Version 1.15-1 of ddrescue has been uploaded.


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.

Ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile
contents, converts logfiles to/from other formats, compares logfiles,
tests rescue status, and can delete a logfile if the rescue is done.
Ddrescuelog operations can be restricted to one or several parts of the
logfile if the domain setting options are used.

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 also features a "fill mode" 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

Cygwin NEWS:

ddrescue does no longer crash if cygstdc++-6.dll from package
libstdc++6-4.5.3-3 is installed.

Upstream NEWS:

Changes in version 1.13:

Non-regular output files are no more overwritten by default.

The option "--force", which forces overwriting of non-regular output
files has been added.

The option "--preallocate", which preallocates space on disc for output
file has been added.

The command line used is now written to the logfile as information for
the user.

Even more warnings have been added to the tutorial in the manual.

Revert to use "long" instead of "time_t" for time variables. Ddrescue
only needs counting seconds and "time_t" causes warnings on some

Changes in version 1.14:

The new option "-R, --reverse", which reverses direction of copy
operations, has been added.

The new option "-E, --max-error-rate", which stops ddrescue when the
error size grows too fast (in Bytes/s), has been added.

The syntax of option "--max-errors" has been extended to specify new
errors (--max-errors=+N).

The short name of option "--retrim" has been changed to "-M".

A spurious warning about "preallocation not available" has been fixed.

Changes in version 1.15:

The new option "-a, --min-read-rate" has been added.

The new option "-I, --verify-input-size" has been added.

The new option "-x, --extend-outfile" has been added.

Ddrescue now verifies that infile, outfile and logfile are all

Non-tried blocks are now read aligned to cluster-size sectors.

The "split or skip" algorithm of the split pass has been improved.

A spurious warning about "-D" being ignored in fill mode has been

Ddrescuelog, a tool for manipulation, display, conversion, comparison
and testing of ddrescue logfiles, has been added.
