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 '--ignore-empty', which makes lziprecover ignore empty members in multimember files when decompressing, testing, or listing, has been added. By default lziprecover now exits with error status 2 if any empty member is found in a multimember file. The option '--ignore-nonzero', which makes lziprecover ignore a nonzero first byte in the LZMA stream when decompressing or testing, has been added. By default lziprecover now exits with error status 2 if the first LZMA byte is nonzero in any member of the input files. The option '--clear-marking' has been renamed to '--nonzero-repair'. Options '--empty-error' and '--marking-error' have been removed. Lzip 1.16 (or clzip 1.6) or newer is required to run the tests.
