2012-06-11 Antonio Diaz Diaz <ant_diaz@teleline.es>
* Version 1.16 released.
* Added new option '-K, --skip-size'.
* Added new option '-T, --timeout'.
* Changed short name of option '--try-again' 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.
* Set current_pos to end of block when reading backwards.
* The '-E, --max-error-rate' option now checks the rate of
actually failed reads, not the growth of error size.
* The option '-v, --verbose' now increases verbosity if repeated.
* Changed quote characters in messages as advised by GNU Standards.
* configure: 'datadir' renamed to 'datarootdir'.
* New files rational.h, rational.cc.

* Version 1.15 released.
* Added new option '-a, --min-read-rate'.
* Added new option '-I, --verify-input-size'.
* Added new option '-x, --extend-outfile'.
* main.cc: Verify that infile, outfile and logfile are all
different.
* Non-tried blocks are now read aligned to cluster-size sectors.
* rescuebook.cc: Improved skip algorithm for the split pass.
* main.cc: Removed spurious warning about '-D' ignored in fill mode.
* ddrescue.texinfo: Improved description of algorithm.
* logbook.cc (change_chunk_status): Return an adjust value (-1, 0, 1)
to keep "errors" updated without calling count_errors every time.
* ddrescue.cc: Renamed to io.cc.
* Added 'ddrescuelog', a program for logfile manipulation.
2011-01-10 Antonio Diaz Diaz <ant_diaz@teleline.es>

warnings on some systems.
