As +the announcement points out, some 200 people contributed more than +10,000 commits since the previous release. This post focuses on +important changes for HPC users, admins, and scientists made since +version 1.1.0 was released in April 2020. + +# Reproducible science workflows + +We’re giving users more flexibility on the command line, with the +addition of three [*package transformation +options*](https://guix.gnu.org/manual/en/html_node/Package-Transformation-Options.html): +`--with-debug-info` ([always debug in good +conditions](https://guix.gnu.org/manual/devel/en/html_node/Rebuilding-Debug-Info.html)!), +`--with-c-toolchain`, and `--without-tests`. Consider this example: + +``` +guix build octave-cli \ + --with-c-toolchain=fftw=gcc-toolchain@10 \ + --with-c-toolchain=fftwf=gcc-toolchain@10 +``` + +The command above builds a variant of the fftw and fftwf packages using +version 10 of gcc-toolchain instead of the default tool chain, and then builds +a variant of the GNU Octave command-line interface using them. GNU Octave +itself is also built with gcc-toolchain@10. + +This other example builds the Hardware Locality (hwloc) library and its +dependents up to intel-mpi-benchmarks with the Clang C compiler: + +``` +guix build --with-c-toolchain=hwloc=clang-toolchain \ + intel-mpi-benchmarks +``` + +On the side of long-term archival of all the software Guix packages refer to, +Guix now serves the file [`sources.json`](http://guix.gnu.org/sources.json) +that is ingested by [Software Heritage](https://softwareheritage.org) via the +[nixguix +loader](https://docs.softwareheritage.org/devel/_modules/swh/loader/package/nixguix.html). +In addition to the “archival” check of `guix lint` which sends a “save” +request to Software Heritage for the specified packages. More packages are +continuously archived. + +The new option `--path` of [`guix +graph`](https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-graph.html), +shows the shortest path between two nodes. The example below shows the +shortest path between the packages gmsh and cunit: + +``` +guix graph --path gmsh cunit +firstname.lastname@example.org +email@example.com +firstname.lastname@example.org +email@example.com + +``` + +Moreover, the command [`guix +repl`](https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-repl.html) +can now be passed a script which ease [package exploratinon in +Guile](https://hpc.guix.info/blog/2020/01/reproducible-computations-with-guix/) +especially when dealing with the new Scheme `(guix transformation)` module for +package transformations. And the section [“Programming +Interface”](https://guix.gnu.org/manual/devel/en/html_node/Programming-Interface.html) +of the *reference manual* has been greatly expounded. + +The [`guix +pack`](https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-pack.html#Invoking-guix-pack) +command creates “application bundles” that can be used to deploy software on +machines that do not run Guix (yet!), such as HPC clusters. Since its +[inception in +2017](https://guix.gnu.org/blog/2017/creating-bundles-with-guix-pack/), it has +seen a number of improvements. The relocatable packs can be now [faster by +the addition of the Fakechroot +engine](https://hpc.guix.info/blog/2020/05/faster-relocatable-packs-with-fakechroot/). + + +# Packages + +Here are highlights among the 2,179 packages added and 4,487 packages +upgraded since the previous release: + + - [Gmsh](https://hpc.guix.info/package/gmsh) has been upgraded to 4.6.0. + - [MPICH](https://hpc.guix.info/package/mpich) is now at 3.3.2. + - [Open MPI](https://hpc.guix.info/package/openmpi) is now at 4.0.5. + - [GCC](https://hpc.guix.info/package/gcc-toolchain) 10.2.0 is + available and [LLVM, Clang](https://hpc.guix.info/package/clang-toolchain) + 11.0.0 too. + - [Julia](https://hpc.guix.info/package/julia) has been upgraded to + 1.5.2. + - [MPI4PY](https://hpc.guix.info/package/python-mpi4py) is at + 3.0.3. + - For statisticians, there’s now a total of 1,488 R packages, many of + which comes from [Bioconductor](https://www.bioconductor.org/) 3.11. + +Last but not least, *the manual is fully translated* to +[French](https://guix.gnu.org/manual/fr/html_node/), +[German](https://guix.gnu.org/manual/de/html_node/), and +[Spanish](https://guix.gnu.org/manual/es/html_node/), with partial +translations in [Russian](https://guix.gnu.org/manual/ru/html_node/) and +[Chinese](https://guix.gnu.org/manual/zh-cn/html_node/). + +Do not miss the [release +notes](https://guix.gnu.org/blog/2020/gnu-guix-1.2.0-released/) for more. + +### Try it! + +We want Guix to be accessible and useful to a broad audience and that +has again been a guiding principle for this release. The [graphical +system +installer](https://guix.gnu.org/en/videos/system-graphical-installer/) +and the [script to install Guix on another +distro](https://guix.gnu.org/manual/en/html_node/Binary-Installation.html) +have both received bug fixes and usability improvements. First-time +users will appreciate the fact that `guix help` now gives a clear +overview of the available commands, that `guix` commands are less +verbose by default, and that `guix pull` displays a progress bar as it +updates its Git checkout. + +We’ve been told [you may soon be able to `apt install +guix`](https://packages.debian.org/guix) if you’re on Debian or a derivative +distro!—[get in touch with us](https://guix.gnu.org/en/contact/). + +Enjoy the new release! base-commit: 67a725bebe63d3933ae133da2bc5d778994dbc39 -- 2.28.0
