    Release Notes: The main focus of this release has been the improvement of the status output. It has rate limiting (10/s), optional colors, and a few consistency improvements. Beyond that, there's a simple rewrite logic for write errors, and SSE2 optimized sparse detection is included.

      Release Notes: Minor bugs were fixed. A bunch of minor code adjustments were made to improve compilation on many compilers (including C++) and more *nix systems. Specifically, there were fixes for FreeBSD. dd_rescue can now load libfallocate at runtime (with libdl), if you want to build it that way. Some more write errors are now treated as fatal to avoid pointless repeats.

        Release Notes: dd_rescue 1.33 brings a new double-overwrite (random and zero) mode. More importantly, dd_rescue now supports long options and has a man page that properly documents all the options and modes.

          Release Notes: This release adds two new options: -x facilitates appending to an output file, and -Y OUTFILE (can be specified multiple times) allows the user to specify secondary output files which receive the same data (at the same position) as the primary output file.

            Release Notes: This release brings a few minor cleanups (messages) and one feature: it now has a mode where the output file/partition/disk is overwritten two (-3) or three (-4) times with random data and finally with zeros. This supports secure data destruction according to German data privacy standards from BSI.

              Release Notes: -p correctly copies access times, output to stdout works, and the progress info is always updated when exiting. This release fixes copying the last block with hardbs==softbs. Better option validation. Allows for 512 byte blocks with direct I/O now, and has better defaults for block sizes. Optimization for writing the same block again and again (-R). Can write random data (e.g. -z seedval or -Z /dev/urandom) using the libc or Eli Billauer's RC4 based PRNG. Writes can be avoided if the output file/device already contains identical contents (-W). Builds .deb binaries.

                Release Notes: Changes since the last published version (1.20) include additional warnings for overwriting existing files in sparse mode, documentation improvements, an FPE bugfix for reverse copy, really defaulting to -y 0 (not syncing except at the end), not considering EOF an error and displaying better error messages (errno was overwritten in one scenario), portability improvements, and fixes for the output of bad blocks.

                  Release Notes: This release brings support for fallocate (to tell the filesystem how large the resulting target file will be, so it can avoid fragmentation better). It also enables a progress indicator when the input file size is not known (e.g. a pipe or /dev/zero) but the maximum transfer length has been set with -m.

                    Release Notes: This release include some fixes (sparse writing, filling 0 when read errors occur) and some better error handling (consider ENOSPC fatal, don't repeat warnings for failed fsyncs). The program now defaults to -y0, meaning no fsyncs. Optionally, dd_rescue can now use the splice system call (on Linux) to do avoid copying of data in memory. The output of the program is now better, allowing the user to see better on what operation (read, write, fsync) warnings or errors occurred. Most importantly, there is a progress bar now, with a completion percentage and an ETA displayed.

                      Release Notes: The options -b and -y have been added. -b logs the numbers of bad blocks in an ASCII file, suitable for the mke2fs -l option (but beware to match hard block size with mke2fs). The -y option sets the frequency of fsync() on the output file; -y 0 results in the maximum speed.
