Changes in version 1.25: The option '-F, --fec', which implements Forward Error Correction (FEC), has been added. The options '-0' to '-9' (FEC fragmentation level) have been added. The option '-b, --block-size', which sets the FEC block size, has been added. The option '--fec-file', which sets the fec file to be used, has been added. The options '-r, --recursive' and '-R, --dereference-recursive' have been added for recursive creation and reading of fec files. The short name of option '--byte-repair' has been changed to '-B'. The option '--byte-repair' now repairs a nonzero first LZMA byte. When decompressing, testing, or listing, lziprecover now exits with error status 2 if any empty member is found in a regular multimember file unless '-i' is given. When decompressing or testing, lziprecover now exits with error status 2 if the first byte of the LZMA stream is not 0 unless '-i' is given. The option '--clear-marking' has been renamed to '--nonzero-repair'. Options '--empty-error' and '--marking-error' have been removed. The chapter 'Syntax of command-line arguments' has been added to the manual. Lzip 1.16 (or clzip 1.6) or newer is required to run the tests.
