Jim [on behalf of the grep maintainers]
==================================================================

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=v3.4
or run this command from a git-cloned grep directory:
git shortlog v3.3..v3.4

To summarize the 819 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v3.4
git submodule summary v3.3

==================================================================
Here are the compressed sources and a GPG detached signature[*]:
https://ftp.gnu.org/gnu/grep/grep-3.4.tar.xz
https://ftp.gnu.org/gnu/grep/grep-3.4.tar.xz.sig

Use a mirror for higher download bandwidth:
https://ftpmirror.gnu.org/grep/grep-3.4.tar.xz
https://ftpmirror.gnu.org/grep/grep-3.4.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-3.4.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-dirty
Automake 1.16a
Gnulib v0.1-3121-gc3c36de58

NEWS

* Noteworthy changes in release 3.4 (2020-01-02) [stable]

** New features

The new --no-ignore-case option causes grep to observe case
distinctions, overriding any previous -i (--ignore-case) option.

** Bug fixes

'.' no longer matches some invalid byte sequences in UTF-8 locales.
[bug introduced in grep 2.7]

grep -Fw can no longer false match in non-UTF-8 multibyte locales
For example, this command would erroneously print its input line:
echo ab | LC_CTYPE=ja_JP.eucjp grep -Fw b
[Bug#38223 introduced in grep 2.28]

The exit status of 'grep -L' is no longer incorrect when standard
output is /dev/null.
[Bug#37716 introduced in grep 3.2]

A performance bug has been fixed when grep is given many patterns,
each with no back-reference.
[Bug#33249 introduced in grep 2.5]

A performance bug has been fixed for patterns like '01.2' that
cause grep to reorder tokens internally.
[Bug#34951 introduced in grep 3.2]

** Build-related

The build procedure no longer relies on any already-built src/grep
that might be absent or broken. Instead, it uses the system 'grep'
to bootstrap, and uses src/grep only to test the build. On Solaris
/usr/bin/grep is broken, but you can install GNU or XPG4 'grep' from
the standard Solaris distribution before building GNU Grep yourself.
[bug introduced in grep 2.8]
