Changes in version 1.27:

The new argument 'append' has been added to option '-F, --fec'. It appends
a recovery record to each input file.

The FEC fragmentation level is now specified as the second argument to option
'-F, --fec'. Options '-0' to '-9' will be removed in version 1.28.

The FEC unit block size is now specified as the third argument to option
'-F, --fec'. Option '-b, --block-size' will be removed in version 1.28.

The new option '--check-cl' has been added. It checks that all the options
and arguments preceding this option in the command line can be parsed
successfully and exits. This option is used by tarlz to parse the '-F, --fec'
option when calling lziprecover to create a recovery record for an archive.

The option '--append=<file>' now can append trailing data to non-lzip files.

Options '--dump' and '--strip' now can manage trailing data in non-lzip files.

The option '--remove' now can remove trailing data from non-lzip files.

'--fec=create' now keeps the block size greater or equal than the number of
data blocks, and writes two chksum packets to avoid a single point of
failure when the fec file contains more than one fec block.

'--fec=list', '--fec=repair', and '--fec=test' now also work on files
protected by a recovery record (fec data appended to the file).

'--fec=repair', and '--fec=test' now show the percentage damaged of the
protected data.

When producing repaired files, the name of the repaired file is now composed
by prepending the string "fixed_" to the basename of the original file name.

Make '-F, --fec' create by default 9 FEC blocks (instead of 8) because 9
blocks of minimum size (512 bytes) make more than 4096 bytes, preventing a
single-sector error from disabling a whole recovery record.

The option '-S, --nrep-stats' now runs a G-test for uniformity (an improved
type of chi-squared test) to check that the LZMA data in the input lzip
files follow a uniform distribution (all byte values are equally probable).
(The LZMA data generated by lzip reaches a high level of pseudo-randomness,
increasing the security of any subsequent encryption).

The option '-D, --range-decompress' now detects and reports mismatches
between index and members' contents.

The option '-z, --zcmp=<command>' of unzcrash now accepts quotes anywhere,
not only at begin and end of an argument. For example,
--zcmp="zcmp '--lz=plzip -n2'" can now be written as
--zcmp="zcmp --lz='plzip -n2'".

The new section 'Structure of a TDATABOX' has been added to the manual.
