For a summary of changes and contributors, see:
http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v2.27
or run this command from a git-cloned grep directory:
git shortlog v2.26..v2.27
To summarize the 98 gnulib-related changes, run these commands
from a git-cloned grep directory:
git checkout v2.27
git submodule summary v2.26

[*] 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-2.27.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 2.69.171-527f1
Automake 1.99a
Gnulib v0.1-995-gca3ca77

NEWS
* Noteworthy changes in release 2.27 (2016-12-06) [stable]
** Bug fixes
grep no longer reports a false match in a multibyte, non-UTF8 locale
like zh_CN.gb18030, with a regular expression like ".*7" that just
happens to match the 4-byte representation of gb18030's \uC9, the
final byte of which is the digit "7".
[bug introduced in grep-2.19]
grep by default now reads all of standard input if it is a pipe,
even if this cannot affect grep's output or exit status. This works
better with nonportable scripts that run "PROGRAM | grep PATTERN
>/dev/null" where PROGRAM dies when writing into a broken pipe.
[bug introduced in grep-2.26]
grep no longer mishandles ranges in nontrivial unibyte locales.
[bug introduced in grep-2.26]
grep -P no longer attempts multiline matches. This works more
intuitively with unusual patterns, and means that grep -Pz no longer
rejects patterns containing ^ and $ and works when combined with -x.
[bugs introduced in grep-2.23] A downside is that grep -P is now
significantly slower, albeit typically still faster than pcregrep.
grep -m0 -L PAT FILE now outputs "FILE". [bug introduced in grep-2.5]
To output ':' and tab-align the following character C, grep -T no
longer outputs tab-backspace-':'-C, an approach that has problems if
run inside an Emacs shell window. [bug introduced in grep-2.5.2]
grep -T now uses worst-case widths of line numbers and byte offsets
instead of guessing widths that might not work with larger files.
[bug introduced in grep-2.5.2]
grep's use of getprogname no longer causes a build failure on HP-UX.
** Improvements
grep no longer reads the input in a few more cases when it is easy
to see that matching cannot succeed, e.g., 'grep -f /dev/null'.
