vibeqc 0.1.0 First tagged release. Molecular: RHF, UHF, RKS, UKS, RMP2, UMP2 with analytic gradients, Pulay DIIS, SAD/Hcore guesses, validated against PySCF to machine precision. 500+ XC functionals via libxc. Periodic: 1D/2D/3D infrastructure, Gamma-only and multi-k RHF, multi-k KS-DFT (LDA/GGA). spglib for crystal symmetry. POSCAR I/O. Monkhorst-Pack k-meshes with IBZ reduction. Periodic results are validated in the molecular-limit regime; 3D bulk goes quantitative in v0.2.0 when Ewald lands. Basis sets: 90 standard molecular bases from libint plus pob-TZVP, pob-TZVP-rev2, pob-DZVP-rev2 (Peintinger-Vilela Oliveira-Bredow solid-state bases) imported via a CRYSTAL-format parser. Documentation: Sphinx + Furo + MyST at docs/, MPL 2.0 license, 276 regression tests.
