Release Notes: This release skips faster over damaged areas. A new pass has been added that trims error areas backward before splitting. Support for sparse output files has been added. Blocks are now split at sector boundaries. The new option "--fill" has been added. This release can resume an interrupted retry pass instead of reinitiating it. It achieves perfect resumability if interrupted during trimming or splitting and handles SIGHUP and SIGTERM. The "--quiet" option quiets error messages. Consistency checks have been added to detect bugs.
Release Notes: This release adds the new option "-w, --ignore-write-errors", which makes fill mode ignore write errors. This is useful to avoid ddrescue exiting because of new errors developing while wiping the good sectors of a failing drive.
Release Notes: Ddrescuelog no longer says that the logfile does not exist when it exists but is empty. The manual now explains that only whole sectors can be read when "direct disc access" is used.
Release Notes: The option "-l, --logfile-size" has been added. Trimming is now done from both edges of each non-trimmed block. The largest blocks are trimmed first. The largest blocks are now split first until logfile reaches "--logfile-size" entries.
Release Notes: The option "--sector-size" has been added as a synonym of "--block-size". Ddrescue now terminates with an error if an unexpected EOF would discard any successfully read data, and automatically adjusts the logfile to shrinking input devices, like CD-ROMs written in TAO mode. A bug has been fixed which prevented status updating after the system clock had been put back. Control-C no longer overwrites status messages. Generate mode no longer requires the "--force" option. The new chapter "Using ddrescue safely" has been added to the manual.
Release Notes: The new options "-K, --skip-size" and "-T, --timeout" have been added. The short name of option "--try-again" has been changed to "-A". Maximum skip size is now limited to 1% of infile size or 1 GiB (whichever is smaller). The current position is now set to the end of the block when reading backwards, allowing perfect resumability also in reverse mode. 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. The option "-v, --verbose" now increases verbosity if repeated.
