This is to announce grep-2.10, a bug-fix release.

    http://www.gnu.org/s/grep/
    grep searches files for lines containing a match to a specified pattern

It's been nearly five months and 80 commits since 2.9, yet few big
changes in grep proper.  However, there have been many changes in gnulib,
including a few portability fixes that affect grep.

See the NEWS below, or for a more complete summary of changes and
contributors, see:
  http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.10
or run this command from a git-cloned grep directory:
  git shortlog v2.9..v2.10

As usual, we inherit many portability and robustness improvements
by using gnulib.  To summarize its 750+ changes, run these commands
from a git-cloned grep directory:
  git checkout v2.9
  git submodule summary v2.10

Here are the compressed sources and a GPG detached signature[*]:
  http://ftp.gnu.org/gnu/grep/grep-2.10.tar.xz
  http://ftp.gnu.org/gnu/grep/grep-2.10.tar.xz.sig

Use a mirror for higher download bandwidth:
  http://ftpmirror.gnu.org/grep/grep-2.10.tar.xz
  http://ftpmirror.gnu.org/grep/grep-2.10.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-2.10.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 2.68.95-e0cb9
  Automake 1.11a
  Gnulib v0.0-6628-g4f6a7ef

NEWS

* Noteworthy changes in release 2.10 (2011-11-16) [stable]

** Bug fixes

  grep no longer mishandles high-bit-set pattern bytes on systems
  where "char" is a signed type. [bug appears to affect only MS-Windows]

  grep now rejects a command like "grep -r pattern . > out",
  in which the output file is also one of the inputs,
  because it can result in an "infinite" disk-filling loop.
  [bug present since "the beginning"]

** Build-related

  "make dist" no longer builds .tar.gz files.
  xz is portable enough and in wide-enough use that distributing
  only .tar.xz files is enough.
