All releases of GNU ddrescue
Release Notes: The "-E, --max-error-rate" option now checks the rate of actually failed reads, not the growth of error size, and shows the error rate in the error message. Quote characters in messages have been changed as advised by GNU Coding Standards.
Release Notes: The options "-a, --min-read-rate", "-I, --verify-input-size", and "-x, --extend-outfile" have been added. Ddrescue now verifies that infile, outfile, and logfile are all different. 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 removed. Ddrescuelog, a tool for manipulation, display, conversion, comparison, and testing of ddrescue log files, has been added.
Release Notes: The new options "-I, --verify-input-size", and "-x, --extend-outfile" have been added. Ddrescue now verifies that infile, outfile, and logfile are all different. Non-tried blocks are now read aligned to cluster-size sectors. The "split or skip" algorithm of the split pass has been improved. The default block size for ddrescuelog has been changed to 512, the value used by ddrescue.
Release Notes: The "-a, --min-read-rate" option now uses additional passes, dividing rate by ten on each pass. The new options "-a, --change-types", "-c, --create-logfile", "-d, --delete-if-done", "-D, --done-status", "-m, --domain-logfile", "-n, --invert-logfile", "-p, --compare-logfile", "-t, --show-status", "-x, --xor-logfile", "-y, --and-logfile", and "-z, --or-logfile" have been added to ddrescuelog.
Release Notes: The new option "-a, --min-read-rate" has been added. A spurious warning about option "-D" being ignored in fill mode has been removed.
Release Notes: Ddrescuelog, a tool for conversion and manipulation of ddrescue logfiles, has been added.
Release Notes: 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 the option "--max-errors" has been extended to specify new errors (--max-errors=+N). The short name of the option "--retrim" has been changed to "-M". A spurious warning about "preallocation not available" has been fixed.

The code implementing logfile generation has been moved to the new class "Genbook" in preparation for the addition of the reverse mode.
