+We are pleased to announce the new release of GNU Guix and GuixSD,
+version 0.16.0!  This release is (hopefully!) the last one before 1.0—we
+have been closing [most key items for
+1.0](https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/doc/1.0.org)
+over the last few months.
+
+The release comes with [GuixSD ISO-9660 installation
+images](https://www.gnu.org/software/guix/manual/en/html_node/System-Installation.html),
+a [virtual machine image of
+GuixSD](https://www.gnu.org/software/guix/manual/en/html_node/Running-GuixSD-in-a-VM.html),
+and with tarballs to install the package manager on top of your
+GNU/Linux distro, either [from
+source](https://www.gnu.org/software/guix/manual/en/html_node/Requirements.html)
+or [from
+binaries](https://www.gnu.org/software/guix/manual/en/html_node/Binary-Installation.html).
+Guix users can update by running `guix pull`.
+
+It’s been 5 months since the previous release, during which 95 people
+contributed code and packages.  Here are the highlights.
+
+  - The default [substitute
+    
URL](https://www.gnu.org/software/guix/manual/en/html_node/Substitutes.html)
+    has been changed to `https://ci.guix.info`.  This is backed by a
+    more powerful build farm with terabytes of storage kindly donated by
+    the [Bioinformatics platform of the Berlin Institute of Medical
+    Systems Biology (BIMSB) at the Max Delbrück Center
+    (MDC)](https://www.mdc-berlin.de/bioinformatics).  The build farm
+    front-end runs Cuirass, our continuous integration tool that was
+    partly developed during two
+    
[GSoC](https://www.gnu.org/software/guix/blog/2018/gsoc-2018-report-cuirass-web-interface/)
+    
[internships](https://www.gnu.org/software/guix/blog/2016/gnu-guix-welcomes-four-students-for-gsoc/).
+  - `guix pull` now [lists new and upgraded
+    
packages](https://www.gnu.org/software/guix/blog/2018/multi-dimensional-transactions-and-rollbacks-oh-my/),
+    and it has a `--profile` option that allows you to keep several
+    Guix revisions in parallel.  Related to that, the new [`guix
+    
describe`](https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-describe.html)
+    command displays information about the Guix revision you are using.
+  - `guix pull` now supports
+    
[_channels_](https://www.gnu.org/software/guix/manual/en/html_node/Channels.html).
+    In a nutshell, you can specify in `~/.config/guix/channels.scm` the
+    channels from which `guix pull` will fetch Guix as well as,
+    optionally, third-party package repositories.  Again `guix describe`
+    displays all the channels in use and `guix describe -f channels`
+    produces a “pinned channel” specification that can be used as the
+    `channels.scm` file of `guix pull`.
+  - Using the new [_inferior_
+    
mechanism](https://www.gnu.org/software/guix/manual/en/html_node/Inferiors.html),
+    you can now interact with a different revision of Guix and even
+    _compose packages coming from different revisions of Guix_!
+  - The output of the command-line tools has been noticeably improved:
+    important events are colorized, `guix package` and `guix system` no
+    longer display build logs, and `guix build` colorizes build logs (in
+    a way that is similar to what
+    [Emacs-Guix](https://emacs-guix.gitlab.io/website/) does.)
+  - There are new [package transformation
+    
options](https://www.gnu.org/software/guix/manual/en/html_node/Package-Transformation-Options.html):
+    `--with-branch` and `--with-commit` allow you to obtain a package
+    variant straight from its Git repository.
+  - Guix had reproducible builds and now it has “reproducible source
+    code downloads”: when a package refers to a Git repository that has
+    disappeared (which is unfortunately not uncommon!), the checkout can
+    be fetched from [Software
+    Heritage](https://www.softwareheritage.org/).  That makes Guix one
+    of the first distros to be backed by a long-term archive.  See [this
+    issue](https://issues.guix.info/issue/33432) for more info.
+  - Our [Rust](https://www.rust-lang.org) packages are now _fully
+    bootstrapped from source_, starting from
+    [mrustc](https://github.com/thepowersgang/mrustc), a Rust compiler
+    written in C++.  This is a victory on this instance of [“yogurt
+    software”](https://bootstrappable.org/), and Guix is probably the
+    first distro to achieve this.  More on that in a future post!
+  - On GuixSD, `guix system reconfigure` will now always load
+    replacements of system services.  That way, when you deem
+    appropriate, you can run `herd restart SERVICE` to start the
+    upgraded service.
+  - As usual, 985 packages were added and 1,945 were upgraded, notably
+    the GNU C Library now at version 2.28 (which, incidentally, allowed
+    us to [get rid of our Hurd-specific glibc
+    
variant](https://git.savannah.gnu.org/cgit/guix.git/commit/?id=2d546858b139e5fcf2cbdf9958a17fd98803ac4c),
+    at last!).  Today Guix provides [8,715
+    packages](https://guix-hpc.bordeaux.inria.fr/browse).
+  - The manual is now partially [translated into
+    German](https://www.gnu.org/software/guix/manual/de/html_node/).
+    The [French
+    translation](https://www.gnu.org/software/guix/manual/fr/html_node/)
+    is now 90% complete.  You can help [translate the manual into your
+    native
+    language](https://translationproject.org/domain/guix-manual.html) by
+    [joining the Translation
+    Project](https://translationproject.org/html/translators.html).
+
+Pffew, quite a long list already!  The [release
+announcement](https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00141.html)
+lists additional noteworthy changes and bug fixes you may be interested
+in.
+
+Enjoy!
+
+#### About GNU Guix
+
+[GNU Guix](https://www.gnu.org/software/guix) is a transactional package
+manager for the GNU system.  The Guix System Distribution or GuixSD is
+an advanced distribution of the GNU system that relies on GNU Guix and
+[respects the user's
+freedom](https://www.gnu.org/distros/free-system-distribution-guidelines.html).
+
+In addition to standard package management features, Guix supports
+transactional upgrades and roll-backs, unprivileged package management,
+per-user profiles, and garbage collection.  Guix uses low-level
+mechanisms from the Nix package manager, except that packages are
+defined as native [Guile](https://www.gnu.org/software/guile) modules,
+using extensions to the [Scheme](http://schemers.org) language.  GuixSD
+offers a declarative approach to operating system configuration
+management, and is highly customizable and hackable.
+
+GuixSD can be used on an i686, x86_64, ARMv7, and AArch64 machines.  It
+is also possible to use Guix on top of an already installed GNU/Linux
+system, including on mips64el and aarch64.
