grep-2.12 released [stable]
Item posted by Jim Meyering <meyering> on Tue 24 Apr 2012 08:57:07 AM UTC.
This is to announce grep-2.12, a stable release.
There have been 22 commits by 3 people in the 7 weeks since 2.11.
In spite of the relatively small number of commits, this is a
significant delta, with two regression fixes, Paul's conversion,
from grep's crufty old dir-traversal code to the use of gnulib's fts
and the change to how -r (--recursive) works.
See the NEWS below for a brief summary.
Thanks to everyone who has contributed!

For a summary of changes and contributors, see:
http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.12
or run this command from a git-cloned grep directory:
git shortlog v2.11..v2.12
To summarize the 366 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v2.12
git submodule summary v2.11

[*] 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-2.12.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 2.68b.19-eaa96
Automake 1.11e
Gnulib v0.0-7338-gd06b2e5

NEWS
* Noteworthy changes in release 2.12 (2012-04-23) [stable]
** Bug fixes
"echo P|grep --devices=skip P" once again prints P, as it did in 2.10
[bug introduced in grep-2.11]
grep no longer segfaults with -r --exclude-dir and no file operand.
I.e., ":|grep -r --exclude-dir=D PAT" would segfault.
[bug introduced in grep-2.11]
Recursive grep now uses fts for directory traversal, so it can
handle much-larger directories without reporting things like "File
name too long", and it can run much faster when dealing with large
directory hierarchies. [bug present since the beginning]
grep -E 'a{1000000000}' now reports an overflow error rather than
silently acting like grep -E 'a\{1000000000}'.
** New features
The -R option now has a long-option alias --dereference-recursive.
** Changes in behavior
The -r (--recursive) option now follows only command-line symlinks.
Also, by default -r now reads a device only if it is named on the command
line; this can be overridden with --devices. -R acts as before, so
use -R if you prefer the old behavior of following all symlinks and
defaulting to reading all devices.
