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.
Release Notes: If ddrescue is interrupted by a signal, it now terminates by raising the signal received. The algorithm of the copying phase has been changed. It now marks as non-trimmed just the failed blocks, skips beyond them, and tries the skipped areas later in additional passes (before trimming), reversing the direction after each pass. The new method produces better starting points for trimming, which now tries the smallest blocks first. The message "About to copy an unknown number of bytes" is now shown when the size of the input file can't be determined.
Release Notes: Blocks skipped during the copying phase are no longer marked as non-trimmed. They are tried in additional passes (before trimming). This speeds the rescue in case of large errors by avoiding the creation of large non-trimmed areas. "ddrescue.texinfo" has been renamed "ddrescue.texi".
Release Notes: The new option "-L, --loose-domain" has been added to ddrescue and ddrescuelog. The new option "-N, --no-trim" has been added to ddrescue. The default value of option "-a, --min-read-rate" has been restored to its original value (disabled). The option "-B, --binary-prefixes" has been ported to ddrescuelog. The new option "-C, --complete-logfile" has been added to ddrescuelog. A code reorganization has been made. The new class 'Logfile' has been added.
Release Notes: The long name of the option "-r" has been changed to "--retry-passes" to make it clear that ddrescue tries each sector only once per retry pass. The default value of option "-a, --min-read-rate" has been changed to 0 (auto). The effect of option '-O, --reopen-on-error' is now limited to the copying phase, but it also reopens the file on slow reads.
Release Notes: The new option "-O, --reopen-on-error" has been added.
