grep-2.14 released [stable]

This is to announce grep-2.14, a stable release.

It is unusual to make a new release after so few changes, but it
is even more unusual to discover that a command like grep -i '^$'
can malfunction.  It could report a match even though there was none.

There have been 17 commits by 2 people in the 7 weeks since 2.13.

See the NEWS below for a brief summary.

Thanks to everyone who has contributed!
The following people contributed changes to this release:

  Jim Meyering (12)
  Paul Eggert (5)

Jim [on behalf of the grep maintainers]

Here is the GNU grep home page:

For a summary of changes and contributors, see:;a=shortlog;h=v2.14
or run this command from a git-cloned grep directory:
  git shortlog v2.13..v2.14

To summarize the 72 gnulib-related changes, run these commands
From a git-cloned grep directory:
  git checkout v2.14
  git submodule summary v2.13

Here are the compressed sources and a GPG detached signature[*]:

Use a mirror for higher download bandwidth:

[*] 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-2.14.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 --recv-keys 7FD9FCCB000BEEEE

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.69.19-1bb10
  Automake 1.12a
  Gnulib v0.0-7573-ga451aa0


* Noteworthy changes in release 2.14 (2012-08-20) [stable]

** Bug fixes

  grep -i '^$' could exit 0 (i.e., report a match) in a multi-byte locale,
  even though there was no match, and the command generated no output.
  E.g., seq 2 | LC_ALL=en_US.utf8 grep -il '^$' would mistakenly print
  "(standard input)".  Related, seq 9 | LC_ALL=en_US.utf8 grep -in '^$'
  would print "2:4:6:8:10:12:14:16" and exit 0.  Now it prints nothing
  and exits with status of 1.  [bug introduced in grep-2.6]

  'grep' no longer falsely reports text files as being binary on file
  systems that compress contents or that store tiny contents in metadata.
