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

Here is the GNU diffutils home page:
http://gnu.org/s/diffutils/

For a summary of changes and contributors, see:
http://git.sv.gnu.org/gitweb/?p=diffutils.git;a=shortlog;h=v3.6
or run this command from a git-cloned diffutils directory:
git shortlog v3.5..v3.6

To summarize the 565 gnulib-related changes, run these commands
from a git-cloned diffutils directory:
git checkout v3.6
git submodule summary v3.5

Here are the compressed sources and a GPG detached signature[*]:
http://ftp.gnu.org/gnu/diffutils/diffutils-3.6.tar.xz
http://ftp.gnu.org/gnu/diffutils/diffutils-3.6.tar.xz.sig

Use a mirror for higher download bandwidth:
http://ftpmirror.gnu.org/diffutils/diffutils-3.6.tar.xz
http://ftpmirror.gnu.org/diffutils/diffutils-3.6.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 diffutils-3.6.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 2.69.185-b502e
Automake 1.99a
Gnulib v0.1-1390-g809f19d

* Noteworthy changes in release 3.6 (2017-05-21) [stable]

** New features

When one file is a prefix of the other, cmp now appends the shorter
file's size to the EOF diagnostic.

** Bug fixes

Using an invalid regular expression with --ignore-matching-lines=RE (-I)
no longer causes stack overflow. Before, with an invocation like the
following, diff would diagnose the error, but would still proceed to
blow the stack: diff -Ia -I\\ <(echo) <(echo b)
[bug introduced in 2.9]

diff no longer mishandles line numbers exceeding 2**31 on Mingw-w64.

the ---presume-output-tty (ostensibly test-only) option would cause
diff --color to read an uninitialized variable
[bug introduced in 3.4]

** Performance changes

diff's default algorithm has been tweaked to deal better with larger
files, reversing some of the changes made in diffutils-3.4.
