This release comes with a nice improvement for many:
grep '[0-9]' can be around 7 times faster in the multibyte
locales that most people use. Thank you, Paul Eggert.
There have been 27 commits by 4 people in the 20 weeks since 3.0.

[*] 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-3.1.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.

NEWS
* Noteworthy changes in release 3.1 (2017-07-02) [stable]
** Improvements
grep '[0-9]' is now just as fast as grep '[[:digit:]]' when run
in a multi-byte locale. Before, it was several times slower.
** Changes in behavior
Context no longer excludes selected lines omitted because of -m.
For example, 'grep "^" -m1 -A1' now outputs the first two input
lines, not just the first line. This fixes a glitch that has been
present since -m was added in grep 2.5.
The following changes affect only MS-Windows platforms. First, the
--binary (-U) option now governs whether binary I/O is used, instead
of a heuristic that was sometimes incorrect. Second, the
--unix-byte-offsets (-u) option now has no effect on MS-Windows too.
