📢 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.

New ORCA 6 Optimizers

📚 If you struggle to manage your references while writing your papers, there's a new Zotero version, and this one is a big step forward for the free reference manager! 🚀

🎉 We’re thrilled to announce the release of Zotero 7! 🎉

Check out the official announcement here: Zotero 7 Release

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.
