This is to announce gzip-1.14, a stable release.
Most notable: "gzip -d" is up to 40% faster on x86_64 CPUs with pclmul
support. Why? Because about half of its time was spent computing a CRC
checksum, and that code is far more efficient now. Even on 10-year-old
CPUs lacking pclmul support, it's ~20% faster. Thanks to Lasse Collin
for alerting me to this very early on, to Sam Russell for contributing
gnulib's new crc module and to Bruno Haible and everyone else who keeps
the bar so high for all of gnulib. And as usual, thanks to Paul Eggert
for many contributions everywhere.
There have been 58 commits by 7 people in the 85 weeks since 1.13.
See the NEWS below for a brief summary.
Thanks to everyone who has contributed!

Bruno Haible (1)

Jim Meyering (26)

Here are the compressed sources:
https://ftp.gnu.org/gnu/gzip/gzip-1.14.tar.gz (1.4MB)
https://ftp.gnu.org/gnu/gzip/gzip-1.14.tar.xz (868KB)
Here are the GPG detached signatures:
https://ftp.gnu.org/gnu/gzip/gzip-1.14.tar.gz.sig
https://ftp.gnu.org/gnu/gzip/gzip-1.14.tar.xz.sig
Use a mirror for higher download bandwidth:

Here are the SHA1 and SHA256 checksums:

Aae4gb0iC/32Ffl7hxj4C9/T9q3ThbmT3Pbv0U6MCsY=3D gzip-1.14.tar.xz
Verify the base64 SHA256 checksum with cksum -a sha256 --check
from coreutils-9.2 or OpenBSD's cksum since 2007.
Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify gzip-1.14.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096/0x7FD9FCCB000BEEEE 2010-06-14 [SCEA]
Key fingerprint =3D 155D 3FC5 00C8 3448 6D1E EA67 7FD9 FCCB 000B E=
EEE
uid [ unknown] Jim Meyering <jim@HIDDEN>
uid [ unknown] Jim Meyering <meyering@HIDDEN>
uid [ unknown] Jim Meyering <meyering@HIDDEN>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --locate-external-key jim@HIDDEN
gpg --recv-keys 7FD9FCCB000BEEEE
wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=
=3Dgzip&download=3D1' | gpg --import -
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify gzip-1.14.tar.gz.sig
This release is based on the gzip git repository, available as
git clone https://git.savannah.gnu.org/git/gzip.git
with commit fbc4883eb9c304a04623ac506dd5cf5450d055f1 tagged as v1.14.
For a summary of changes and contributors, see:
https://git.sv.gnu.org/gitweb/?p=3Dgzip.git;a=3Dshortlog;h=3Dv1.14
or run this command from a git-cloned gzip directory:
git shortlog v1.13..v1.14
This release was bootstrapped with the following tools:
Autoconf 2.72.76-2f64
Automake 1.17.0.91
Gnulib 2025-01-31 553ab924d2b68d930fae5d3c6396502a57852d23
NEWS
* Noteworthy changes in release 1.14 (2025-04-09) [stable]
** Bug fixes
'gzip -d' no longer omits the last partial output buffer when the
input ends unexpectedly on an IBM Z platform.
[bug introduced in gzip-1.11]
'gzip -l' no longer misreports lengths of multimember inputs.
[bug introduced in gzip-1.12]
'gzip -S' now rejects suffixes containing '/'.
[bug present since the beginning]
** Changes in behavior
The GZIP environment variable is now silently ignored except for the
options -1 (--fast) through -9 (--best), --rsyncable, and --synchronous.
This brings gzip into line with more-cautious compressors like zstd
that limit environment variables' effect to relatively innocuous
performance issues. You can continue to use scripts to specify
whatever gzip options you like.
'zmore' is no longer installed on platforms lacking 'more'.
** Performance improvements
gzip now decompresses significantly faster by computing CRCs via a
slice by 8 algorithm, and faster yet on x86-64 platforms that
support pclmul instructions.
