Dear EasyBuilders,

I'm happy to announce the release of EasyBuild version 3.4.1 [1].
You may have already heard... this is the best EasyBuild release ever!

This is primarily a bugfix & update release, but it also adds a couple of minor features.
Highlights include:

    * stable support for 'eb --trace' [2]

    * support for --force-download & --ignore-checksums

    * generic SystemMPI easyblock to install a module for an already available OpenMPI or Intel MPI installation

    * put symlinks in place for cc/c++/f77/f95 commands when installing GCC to shadow available system commands

    * fixed checksums for software for which the sources are downloaded from GitHub (github.com/../../archive source URLs)       * see also https://github.com/easybuilders/easybuild-easyconfigs/issues/5151

    * also consider rdma-core-devel as alternative to libibverbs-devel OS dependency in OpenMPI easyconfigs

    * include NLopt as dependency in R easyconfigs if nloptr extension is installed         * this fixes an infinite loop that occurs when NLopt is being installed during the installation of nloptr

    * support for 13 new software packages, incl. FSLeyes, QEMU, REMORA, SAS

    * updates for already supported software,
       incl. Blender 2.79, matplotlib 2.1.0, OpenCV 3.3.0, OpenFOAM-Extend 4.0, OpenMPI 2.1.2 + 3.0.0, Python 2.7.14 + 3.6.3, etc.


This brings the total number of supported software packages to 1,307 [3]!
A detailed overview of all changes is available in the release notes [4].

Thanks to everyone who contributed to this release in one way or another!


To upgrade to EasyBuild v3.4.1, there are several options, see [5].
Two particularly easy options include:

    * eb --install-latest-eb-release  # requires EasyBuild v3.3.0 or more recent

    * eb --from-pr 5231               # use easyconfig from PR #5231 [6]


(EasyBuild v3.3.0 is required for --install-latest-eb-release because support for SHA256 checksums is required)


Enjoy!

regards,
