July 1, 2013. Version 1.0.1
- Two bug fixes related to reading Gaussian formatted checkpoint files.
- The Gaussian 03 FCHK format contains a spelling error (‘independant’ instead of ‘independent’). This is fixed in Gaussian 09. Both variants are now properly handled by HORTON.
- Post-HF density matrices are read in properly.
- Reorganization of mean-field code. It is now located in a sub package
- It is now impossible to start the SCF-ODA algorithm with a density matrix whose occupation numbers fall out of the admissible range. This prevents fake convergence to nonphysical solutions.

May 23, 2013. Version 1.0
- This release mainly focuses on real-space density partitioning (atoms-in-molecules) methods.
- Other major features include: import wavefunctions from various file formats, basic Hartree-Fock and DFT algorithms (making user of libint and libxc), pruned integration grids up to Ar, checkpointing, …
- Experimental features: ESP fitting of charges and related algorithms, currently only for 3D periodic systems.
