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

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

To summarize the 987 gnulib-related changes, run these commands
from a git-cloned diffutils directory:
git checkout v3.4
git submodule summary v3.3

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

Use a mirror for higher download bandwidth:
http://ftpmirror.gnu.org/diffutils/diffutils-3.4.tar.xz
http://ftpmirror.gnu.org/diffutils/diffutils-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 diffutils-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 2.69.147-5ad35
Automake 1.99a
Gnulib v0.1-820-ge4f1a4a

* Noteworthy changes in release 3.4 (2016-08-08) [stable]

** New features

   diff accepts two new options --color and --palette to generate
   and configure colored output. --color takes an optional argument
   specifying when to colorize a line: --color=always, --color=auto,
   --color=never. --palette is used to configure which colors are used.

** Bug fixes

When binary files differ, diff now exits with status 1 as POSIX requires.
Formerly it exited with status 2.

Unless the --ignore-file-name-case option is used, diff now
considers file names to be equal only if they are byte-for-byte
equivalent. This fixes a bug where diff in an English locale might
consider two Asian file names to be the same merely because they
contain no English characters.

diff -B no longer generates incorrect output if the two inputs
each end with a one-byte incomplete line.

diff --brief no longer reports a difference for unusual identical files.
For example, when comparing a file like /proc/cmdline (for which the linux
kernel reports st_size of 0 even though it is not an empty file) to a
copy of that file's contents residing on a "normal" file system:
    $ f=/proc/cmdline; cp $f k; diff --brief $f k
    Files /proc/cmdline and k differ

** Performance changes

diff's default algorithm has been adjusted to output higher-quality
results at somewhat greater computational cost, as CPUs have gotten
faster since the algorithm was last tweaked in diffutils-2.6 (1993).
