📢 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
