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

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=v2.28
or run this command from a git-cloned grep directory:
  git shortlog v2.27..v2.28

To summarize the 151 gnulib-related changes, run these commands
from a git-cloned grep directory:
  git checkout v2.28
  git submodule summary v2.27

Here are the compressed sources and a GPG detached signature[*]:
  http://ftp.gnu.org/gnu/grep/grep-2.28.tar.xz
  http://ftp.gnu.org/gnu/grep/grep-2.28.tar.xz.sig

Use a mirror for higher download bandwidth:
  http://ftpmirror.gnu.org/grep/grep-2.28.tar.xz
  http://ftpmirror.gnu.org/grep/grep-2.28.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-2.28.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 2.69.185-b502e
  Automake 1.99a
  Gnulib v0.1-1146-gb6acb8d

NEWS

* Noteworthy changes in release 2.28 (2017-02-06) [stable]

** Bug fixes

  When grep -Fo finds matches of differing length, it could
  mistakenly print a shorter one.  Now it prints a longest one.
  [bug introduced in grep-2.26]

  When standard output is /dev/null, grep no longer fails when
  standard input is a file in the Linux /proc file system, or when
  standard input is a pipe and standard output is in append mode.
  [bugs introduced in grep-2.27]

  Fix performance regression with multiple patterns, e.g., for -Fi in
  a multi-byte locale, or for -Fw in a single-byte locale.
  [bugs introduced in grep-2.19, grep-2.22 and grep-2.26]

** Improvements

  Improve performance for -E or -G pattern lists that are easily
  converted to -F format.
