Changes in version 0.30:

The option '-F, --fec' has been ported from lziprecover. When creating a
tar.lz archive, it makes tarlz call lziprecover to either append a recovery
record to the archive or create a .fec (Forward Error Correction) file for
the archive. The goal is to make tarlz a free, tar-compatible alternative to
RAR with recovery record.

Lziprecover 1.27-pre1 or newer is now required to run the tests (make check)
and at runtime (in the PATH) when using option '-F, --fec'.

'--create' and '--append' now ignore sockets instead of reporting them as
"Unknown file type.".

If during '--create' or '--append' a file is (or becomes) shorter than its
reported size, tarlz now pads the tar member with zeros instead of terminating.
