📢 xtb Version 6.7.1 Latest Release 📢
🐞 Bugfix release for the upcoming ORCA 6. 🚀
⚠️ Note: Due to the deprecation of the C++ compiler, the Windows version is 6.7.1pre, as the compilation excluded C-API tests for xtb and CPCM-X and used the previous version of dftd4 (v3.4.0). In the next release, we will likely fully switch to the icx-cl compiler.
📌 What's Changed:
- 🔧 fix no omp build in #984
- 📝 add indentation to CI in #978
- 📦 add dependencies in meson build in #991
- 🛠 fix gfnff restart in #992
- 📈 GFNFF: Update ntrans in latPoint structure in #993
- 💾 reduce memory usage in egbond_hb for GFN-FF in #994
- 🔄 update gfnff_lists JSON output by @Thomas3R in #1005
- 🗂 include preprocessor definitions in #1008
- ➕ add --ceh flag in #1010
- ⚙️ allow disabling cell optimization via command line argument in #1011
- 🛠 fix CI in #1021
- ❌ error tblite/ptb + solvation in #1020
- 📚 update solvation docs in #1028
- 🗺 mapping between tblite and xtb in #1026
- 🔧 refactor geometry optimization (part 2) in #982
- 🔢 increase number of characters for Schoenflies notation from 4 to 6 in #1056
- 🔄 change sign of Fukui indices in #1057
- ✅ fixes #1054 by ensuring thread safety of hessian calculations with GFN-FF in #1061
- 🛡 fix ESP SegFaults with GCC in #728

Elk version 10.0.15 released
Most of the code is now considerably faster without incurring any loss
of precision. This is thanks to more efficient use of the FFT as well as
improved parallelism.
The phonon code has also been enhanced and now includes the non-analytic
term in the dispersion which is calculated using the Born effective
charges and the dielectric function. This gives the correct LO-TO
splitting for polar semiconductors in the q → 0 limit. See the GaAs and
hBC examples in the examples/phonons-superconductivity/ directory.
The ultra long-range ansatz and spin-dependent vector potentials have
been further improved thanks to Wenhan Chen and Eddie Harris-Lee.
Elk has now been in continuous development for over 22 years.
