I am pleased to announce the release of zutils 1.14.
Zutils is a collection of utilities able to process any combination of
compressed and uncompressed files transparently. If any file given,
including standard input, is compressed, its decompressed content is used.
Compressed files are decompressed on the fly; no temporary files are
created. Data format is detected by its identifier string (magic bytes), not
by the file name extension. Empty files are considered uncompressed.
These utilities are not wrapper scripts but safer and more efficient C++
programs. In particular the option '--recursive' is efficient in those
utilities supporting it.
The utilities provided are zcat, zcmp, zdiff, zgrep, ztest, and zupdate.
The formats supported are bzip2, gzip, lzip, xz, and zstd.
Zutils uses external compressors. The compressor to be used for each format
is configurable at runtime.
zcat, zcmp, zdiff, and zgrep are improved replacements for the shell scripts
provided by GNU gzip. ztest is unique to zutils. zupdate is similar to
gzip's znew.

This release is also GPG signed. You can download the signature by appending
'.sig' to the URL. If the 'gpg --verify' command fails because you don't
have the required public key, then run this command to import it:
gpg --recv-keys 8FE99503132D7742
Key fingerprint = 1D41 C14B 272A 2219 A739 FA4F 8FE9 9503 132D 7742
Changes in version 1.14:
* 'zupdate --recursive --destdir=dir' now keeps the file name component
following the last slash in directory arguments:
'zupdate -r -ddir ../a' recompresses the file ../a/b.gz to dir/a/b.lz, while
'zupdate -r -ddir ../a/' recompresses the file ../a/b.gz to dir/b.lz.
* The chapter 'Syntax of command-line arguments' has been added to the
manual.
Please send bug reports and suggestions to zutils-bug@nongnu.org
Regards,
Antonio Diaz, zutils author and maintainer.

If you know someone who is using gzip, bzip2, or xz, please tell him/her
about the advantages of switching to lzip. See
