Here is the GNU grep home page:
http://gnu.org/s/grep/
For a summary of changes and contributors, see:
http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.17
or run this command from a git-cloned grep directory:
git shortlog v2.16..v2.17
To summarize the 26 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v2.17
git submodule summary v2.16
================================
Here are the compressed sources and a GPG detached signature[*]:
http://ftp.gnu.org/gnu/grep/grep-2.17.tar.xz
http://ftp.gnu.org/gnu/grep/grep-2.17.tar.xz.sig
Use a mirror for higher download bandwidth:
http://ftpmirror.gnu.org/grep/grep-2.17.tar.xz
http://ftpmirror.gnu.org/grep/grep-2.17.tar.xz.sig
[*] 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 grep-2.17.tar.xz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys 7FD9FCCB000BEEEE
and rerun the 'gpg --verify' command.
This release was bootstrapped with the following tools:
Autoconf 2.69.117-1717
Automake 1.99a
Gnulib v0.1-76-g497f4cd
================================
NEWS
* Noteworthy changes in release 2.17 (2014-02-17) [stable]
** Improvements
grep -i in a multibyte locale is now typically 10 times faster
for patterns that do not contain \ or [.
grep (without -i) in a multibyte locale is now up to 7 times faster
when processing many matched lines.
** Maintenance
grep's --mmap option was disabled in March of 2010, and began to
elicit a warning in January of 2012. Now it is completely gone.
