-There are 2 new INCAR tags for VASP 6 patch, `LFIX_XY_COL` and `LFIX_Z_COL`. [They fix Cartesian components of the lattice vector, instead of the vector themselves](https://seongjoojung.github.io/posts/update/).

 Both `IBRION=1` and `IBRION=2` works, but if you're trying to converge to a saddle point, only `IBRION=1` works.
