• list of authors and contributors
• generate header file with API functions for Julia bindings
• direct reading of XML UPF-v2 files using pugixml library
• cleanup of tests and unit tests
• introduce real_occupation_matrix setting to enforce Hubbard matrix to be strictly real
• add pseudopotential radial grid cutoff as a parameter instead of a hardcoded 10 a.u. value
• add a code to generate smooth initial magnetisation at a slightly higher initialisation cost
• 'atom' utility is updated to generate high-accuracy LAPW species
• switch to GSL ODE solver for radial equation
• 3-rd order radial derivatives for LAPW functions
• API to set local and non-local occupancy matrices
• API to return major, minor version and revision
• issue a warning for non-optimal k-parallelization
• remove unused input parameters from the schema and move some input parameters to a more logical location
• use strong type for more indices
• iterator over split index
• save magnetisation in JSON output

Fixes:

• sirius_add_hubbard_atom_pair() contained a bug
