Changes in version 1.16:

  * The new option "-K, --skip-size" has been added.

* The new option "-T, --timeout", which sets the maximum time allowed since the last successful read, has 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), rounded to the next multiple of sector size.

* 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.

  * Initial skip size is now shown at verbosity level 1 and above.

* Most user-defined parameters are now shown at verbosity level 2 and above.

* Verbosity level 2 and above adds two lines of initial status showing current position, current sector, and size of last block in logfile.

* Quote characters in messages have been changed as advised by GNU Coding Standards.

* Configure option "--datadir" has been renamed to "--datarootdir" to follow GNU Standards.

Please send bug reports and suggestions to address@hidden

If you are packaging ddrescue for a distribution, please, try to use the lzipped source tarball, as this can improve the support for the lzip format in packaging systems. Thanks.
