Dear EasyBuilders,

I'm happy to announce the release of EasyBuild version 3.4.0 [1].
You guessed it: this is the best EasyBuild release ever!

Highlights include:

    * support for backing up existing modules via --backup-modules before they are regenerated [2]
        * this is enabled automatically with --skip and --module-only

    * support for adding or replacing checksums in easyconfig files via --inject-checksums [3]

    * (experimental) support for "eb --trace" to trace the progress of installations in more detail [4]
        * feedback on the generated output is welcome!

    * updates to the easyblocks for GAMESS-US, MRtrix, ROOT, Siesta + various bug fixes

    * support for 31 new software packages, incl. CLISP, OpenNLP, PHAST, PYTHIA & UNAFold

    * updated easyconfigs for Boost 1.65.0, binutils 2.29, GCC(core) 7.2.0, GAMESS-US 20170420-R1, Perl 5.26.0, ROOT 6.10.04, etc.


This brings the total number of supported software packages to 1,293 [5]!
A detailed overview of all changes is available in the release notes [6].

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


To upgrade to EasyBuild v3.4.0, there are several options, see [7].
Two particularly easy options include:

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

    * eb --from-pr 5107               # use easyconfig from PR #5107 [8]


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


Enjoy!

regards,
