Inconsistent energy for fixed electron occupancies: Rickard Armiento pointed out that the HF total energy for fixed electron occupancies was inconsistent when comparing to 5.4.4 or older versions.
This bug was introduced in 6.1.0 in order to support IALGO=3 in combination with ISMEAR=-2 (for sphpro calculations as post-processing step) but broke the CG algorithms (IALGO=53)
The fix was added in |

ML_ISTART=1 fails for some scenarios: Due to a bug in the rearrangement of the structures found on the ML_AB file, restarting the training of a force field by means of ML_ISTART=1 fails in some cases. N.B.: this problem only occurs in a scenario where one repeatedly restarts the training, and returns to training for a structure that was trained on before (that means exactly same element types and number of atoms per element), but not immediately before. Example: one starts training a force field for structure A, follows this by a continuation run to train for structure B, and then restarts a second time returning to training for structure A again. |

Treatment of the Coulomb divergence in hybrid-functional band-structure calculations is only correct for PBE0: The Coulomb divergence correction for states at and near the Γ-point in hybrid-functional band-structure calculations (see HFRCUT) was only correctly implemented for PBE0 and HFRCUT=-1. Note: HSE band-structure calculations are not expected to be (strongly) affected because this hybrid functional only includes “short-range” Fock exchange. |

Bug in interface with Wannier90 for non-collinear spin calculations: The spin axis for non-collinear spin calculations is not correctly read from the wannier90 input file. This is because this line in the |

Incompatibility with Fujitsu compiler: Fujitsu's Fortran compiler does not support overloaded internal subroutines. A simple workaround is to compile without machine-learning–force-fileds capabilities. Comment out the macro definition of |

Bug in interface with Wannier90 writing UNK when exclude_bands present: The UNK files generated by VASP include all bands where bands specified by `exclude_bands` should be excluded. The fix is to pass the `exclude_bands` array to `get_wave_functions` in mlwf.F. Thanks to Chengcheng Xiao for reporting this bug.
