Since pyiron_atomistics-0.2.29 stresses are by default calculated and stored for VASP calculations. However, the stored values were stored in an undocumented order and had the wrong sign. [497](https://github.com/pyiron/pyiron_atomistics/pull/497) provides a fix by storing the stress as an unambiguous matrix.
- Update to pyiron_base-0.5.0 and add changelog ([501](https://github.com/pyiron/pyiron_atomistics/pull/501))
- Save VASP stresses as matrix ([497](https://github.com/pyiron/pyiron_atomistics/pull/497))
- Drop python3.7 support ([500](https://github.com/pyiron/pyiron_atomistics/pull/500))
- Add cell_only to Vasp.calc_minimize ([498](https://github.com/pyiron/pyiron_atomistics/pull/498))
- Use current structure instead of output to update previous structure ([483](https://github.com/pyiron/pyiron_atomistics/pull/483))
- give possibility of setting log_file in LAMMPS ([488](https://github.com/pyiron/pyiron_atomistics/pull/488))
- Replace Random Atomistics by Lennard Jones in testing ([478](https://github.com/pyiron/pyiron_atomistics/pull/478))
