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

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=v3.2
or run this command from a git-cloned grep directory:
git shortlog v3.1..v3.2

To summarize the 867 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v3.2
git submodule summary v3.1

==================================================================
Here are the compressed sources and a GPG detached signature[*]:
https://ftp.gnu.org/gnu/grep/grep-3.2.tar.xz
https://ftp.gnu.org/gnu/grep/grep-3.2.tar.xz.sig

Use a mirror for higher download bandwidth:
https://ftpmirror.gnu.org/grep/grep-3.2.tar.xz
https://ftpmirror.gnu.org/grep/grep-3.2.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-3.2.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 2.69.197-b8fd7
Automake 1.16a
Gnulib v0.1-2296-g453f37e2b

* Noteworthy changes in release 3.2 (2018-12-20) [stable]

** Changes in behavior

The --files-without-match (-L) option now causes grep to succeed
when a file is listed, instead of when a line is selected. This
resembles what git-grep does.

** Bug fixes

The --recursive (-r) option no longer fails on MS-Windows.
[bug introduced in grep 2.11]

** Improvements

An over-30x performance improvement when many 'or'd expressions
share a common prefix, thanks to improvements in gnulib's dfa.c,
by Norihiro Tanaka. See gnulib commits v0.1-2110-ge648401be,
v0.1-2111-g4299106ce, v0.1-2117-g617a60974

An additional 3-23% speed-up when searching large files, via
increased initial buffer size.

grep now diagnoses stack overflow. Before grep-2.6, the included
regexp code would detect it. Since 2.6, grep defaulted to using
glibc's regexp, which lost that capability.
