==================================================================

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=v2.16
or run this command from a git-cloned grep directory:
git shortlog v2.15..v2.16

To summarize the 56 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v2.16
git submodule summary v2.15

Here are the compressed sources and a GPG detached signature[*]:
http://ftp.gnu.org/gnu/grep/grep-2.16.tar.xz
http://ftp.gnu.org/gnu/grep/grep-2.16.tar.xz.sig

Use a mirror for higher download bandwidth:
http://ftpmirror.gnu.org/grep/grep-2.16.tar.xz
http://ftpmirror.gnu.org/grep/grep-2.16.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-2.16.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 2.69.112-f181
Automake 1.99a
Gnulib v0.1-50-g7a0c729

NEWS

* Noteworthy changes in release 2.16 (2014-01-01) [stable]

** Bug fixes

Fix gnulib-provided maint.mk so that the release procedure described
in README-release actually does what we want. Before that fix, that
procedure resulted in a grep-2.15 tarball that would lead to a grep
binary whose --version-reported version number was 2.14.51...

The fix to make \s and \S work with multi-byte white space broke
the use of each shortcut whenever followed by a repetition operator.
For example, \s*, \s+, \s? and \s{3} would all malfunction in a
multi-byte locale. [bug introduced in grep-2.15]

The fix to make grep -P work better with UTF-8 made it possible for
grep to evoke a larger set of PCRE errors, some of which could trigger
an abort. E.g., this would abort:
printf '\x82'|LC_ALL=en_US.UTF-8 grep -P y
Now grep handles arbitrary PCRE errors. [bug introduced in grep-2.15]

Handle very long lines (2GiB and longer) on systems with a deficient
read system call.
