Dear EasyBuilders,

We're happy to announce the release of EasyBuild v4.6.1 [1].

An independent jury of experts thoroughly evaluated this release, and reached the unanimous conclusion that this is the best EasyBuild release to date!

As usual, there's a lot of attempts to distract you from this, including soaring gas prices, granting rest to The Queen, and a Belgian 22-year old brat winning the Vuelta (w00! \o/). What will they think of next...

The executive summary for this release:

  - various minor bug fixes for EasyBuild framework;
- various bug fixes and enhancements to existing easyconfigs and easyblocks; - easyconfigs for various recent software versions: GATE v9.2, Graphviz v5.0.0, LAMMPS v23Jun2022, OpenFOAM v2206, ...
  - support for installing 37 new software applications and libraries;


EasyBuild v4.6.1 is primarily a bugfix and update release, but it also includes various minor enhancements.

Highlights for this release are listed below. More details are available in the release notes [2] which includes links to the respective pull requests for more detailed information.

## Highlighted enhancements

[enhancements that (may) warrant updating existing installations are marked with (***)]

- run python in the same process as eb wrapper script by using exec (which improves startup performance of eb command);

- reduce the number of command line options for cmake command in CMakeMake generic easyblock;

- enhance PythonPackage easyblock to make sure all test command output makes it to the EasyBuild log, also when return_output_ec=True is used;

- updates and enhancements for various software-specific easyblocks: GROMACS, LAMMPS, libQGLViewer, NVHPC, PyTorch;

- (***) add extra symlinks and sanity checks for libtinfo in ncurses;

- speed up OpenMPI 4.1.4 configure by not running autogen.pl --force, but only running required Autotools commands;


## Prominent bug fixes & changes

[bug fixes or changes that (may) warrant reinstalling easyconfigs are marked with (***)]

- use det_cmake_version function to determine CMake version in CMakeMake generic easyblock (rather than assuming that CMake is loaded as a build dependency);

- don’t enable building of ld.gold when installing binutils on a RISC-V system + don’t configure GCC to use gold as default linker on a RISC-V system;

- make Amber easyblock aware of FlexiBLAS;

- tweak Amber(Tools) easyblock to run tests from top-level directory, and enable running of tests for AmberTools v20 + v21;

- work around miscompilation of OpenBLAS on POWER by compiling with -fstack-protector-strong;

- various fixes for installing PyTorch on POWER systems;

- (***) replace HDF5 v1.13.1 with v1.12.1 as dependency, since we shouldn’t use odd minor versions of HDF5 which are not stable releases;

- (***) use versioned symbols in ncurses built with system toolchain (by adding --with-versioned-syms configure option);

- (***) add CVE patch for XZ 5.2.5 + attempt to fix symbol patch for all OSs;

- (***) add patch for AlphaFold v2.2.2 to fix NaN problem with jax 0.3.9;

- simplify AlphaFold foss/2021a easyconfigs by using a fleshed out patched OpenMM dependency;

- (***) add patch to fix missing sync in LINCS and SETTLE CUDA kernels for GROMACS 2020 and 2021;

- (***) fix checksum for Stacks v2.62 (due to silent re-release without version bump);

- (***) consistently add maeparser + CoordgenLibs dependencies to OpenBabel 3.1.1 easyconfigs;

- (***) update Java/11 to 11.0.16 and Java/17 to 17.0.4;
