I am pleased to announce the release of lziprecover 1.26.
Lziprecover is a data recovery tool and decompressor for files in the lzip
compressed data format (.lz). Lziprecover also provides Forward Error
Correction files (.fec) that can be used to repair any kind of file, not
only lzip files. A fec file can be used as recovery record for a tar.lz archive.
GNU ddrescue provides data recovery capabilities which complement those of
lziprecover. If the cause of file corruption is a damaged medium, the
combination GNU ddrescue + lziprecover is the recommended option for
recovering data from damaged files.

(This release is signed with a new key because the old 1024-bit DSA key
8FE99503132D7742 is no longer accepted by Debian).
Changes in version 1.26:
* '--fec=create' can now process efficiently input files larger than RAM.
If the size of the input file is larger than half the system's RAM,
'--fec=create' now creates all the packets of the fec file concurrently to
avoid reading the input file more than once.
* '--fec=repair' and '--fec=test' can now process input files larger than
RAM.
* '--fec=repair/test/list' now exit immediately with a diagnostic if the
protected file is passed by mistake as the fec file.
* '--fec=repair' now inserts '_fixed' before '.tar' instead of after.
* The new option '--append=<file>', which appends the contents of <file>
as trailing data to another file(s) in a safe way, has been added.
* '-dvv' and '-tvv' now print (de)compressed sizes instead of compression
ratio. (Sizes are more informative than compression ratio).
* Large numbers in option arguments are now accepted with underscore
separators (-b 123_456_789).
* Large numbers are now printed with underscore separators (123_456_789).
* '--list' now can safely skip any trailing data added to a lzip file by
the option '--append'.
* '--list' now prints '+t' after the number of members to indicate the
presence of trailing data, and prints the size of the trailing data below
the size of the last member.
* '-lvv' now prints a blank line between the list of members of each
multimember file and the next file.
* Diagnostics for protected file size mismatch in '--fec=repair/test'
have been improved.
* It has been documented in the manual how to append a fec recovery
record to a tar.lz archive, and how to use it to test and repair the archive.
* 'EXIT STATUS' now has its own section in the man page.
