Thanks, I did title < 72 and body wrapping at 80.  Let me get other
critiques first and I'll post an updated version.

GLEP 42 says Title should be 50 characters or less, and the body
should be wrapped at 72 characters.

Hi everyone,

I'd like to commit the following news item in a couple of days.  I'm
sending it as an attachment so hopefully it'll come across exactly as I
will commit it.

Please review. Thanks.

Upstream development of uClibc has been stalled since July 2015 and there hasn't
been a proper release since May 2012 [1].  New patches addressing important
issues have been submitted but these have not been reviewed nor have they been
committed to the master branch.  Furthermore, backporting even those patches
which have been committed to master is now impractical as too many intermediate
layers of patches conflict.  For all intents and purposes, upstream uClibc is
dead.

Fortunately, a fork called uClibc-ng [2] was begun by Waldemar Brodkorb in
February 2015 and is actively being maintained.  Accordingly, Gentoo's Hardened
uClibc project will be migrating to uClibc-ng as its libc provider.  Currently
stage3 tarballs based on sys-libs/uclibc-ng are available for all supported
arches at [3] and these will become the default after October 5, 2016.  Older
stage3s based on sys-libs/uclibc will be removed.

Unfortunately, migrating a production system from uclibc to uclibc-ng is not
straightforward owing to the central role played by libc.  A migration guide
is provided at [4].  This has been tested on live systems with success, but
the user is cautioned to plan a backup and recovery plan should something go
wrong.
