October 16th, 2012· Ruby: Dialog#filter_kit is implemented.
· Crash when loading a new molecule was fixed.
· ORTEP export did not generate the same orientation as in the screen. Fixed.
· Ruby: Molecule#bond_par, angle_par, dihedral_par, improper_par, vdw_par are made obsolete, and instead MDArena#bond_par, angle_par, dihedral_par, improper_par, vdw_par are implemented. These methods returns the 'cached' parameters in the MDArena. The ParameterRef record for these parameters have a negative index, which represents the parameter belongs to the MDArena instead of the molecule.
· Opening bond/angle/dihedral/improper table now triggers search of MD parameters (but not rebuilding angle/dihedral/improper tables from bond information)
· Handling of view-related attributes of Molecule is improved (specifically, methods like Molecule#show_periodic_image= now work).
· Best-fit plane dialog is not working in Windows; fixed.
· Some fields in md_arena were not properly copied when a molecule is duplicated. Fixed.
· 'Show Graphite' command was using wrong C-C bond length. Fixed.
· Some unused fields of Molecule were removed.
· LAMatrix#svd (singular value decomposition) was implemented.
· Ruby: create_graphic was not working correctly when :ellipsoid is given with a single radius.
· Loading multiple-frame mbsf sometimes fails to load the cell parameter for the last frame. Fixed.
· Property table can now list the unit cell parameters.
· Documents for Dialog#show, Dialog#hide are written. (These were somehow missing)
· Cell minimization was not working correctly when no symmetry operations are defined. Fixed.
· MDArena#prepare was not working correctly when unit cell is added/created after initialization of MDArena. Fixed.
· Handling of selection from Ruby script was partially broken. Fixed.
· Best fit plane dialog was behaving strangely Fixed.
· Handling of Molecule object was not consistent. Hopefully fixed...
· Export ORTEP (improved) and best-fit plane calculations are implemented in Scripts/crystal.rb.
· The revision number is displayed in the about dialog (and is used for labeling clipboard contents)
· Copy/paste of molecules was broken when it had atoms with more than ATOMS_CONNECTS_LIMIT bonds. Fixed.
· Documents for some missing Ruby methods are written.
· Cell minimization is improved (hopefully...)
· Remove printf() for debugging cell minimization
· Implemented minimization of cell parameters. Looks like working...
· Handling of flexible cells were still inconsistent.
· Molecule#cell_flexibility and set_cell_flexibility are implemented, and enable/disable_cell_flexibility are removed.
· Figures for the Ruby tutorial are added to the repository.
· Handling of periodic box during MD is being reworked.
· Ruby: Molecule#box= was not working as expected. Fixed.
· Memory leak bugs are examined and removed.
· amend_by_symmetry in MD was still broken. Hopefully fixed.
· Tutorial for the Ruby interpreter was (finally) written.
· amend_by_symmetry during MD run was causing crash. Fixed.
· Graphite potential calculation is further modified (hope this is complete now!)
· When no molecule is open, Ruby scripts are evaluated in the context of 'main' (the toplevel object)
· Graphite potential calculation is improved.
· The current working directory is set to the document home on startup.
· The anisotropic parameters for the symmetry expanded atoms are now correctly handled.
· Pressure control and surface potential are removed from the GUI; they are not well tested and should be used with great care.
· The load commands can now include error messages in Ruby exception.
· MD minimize was not working properly (especially for the second run with the same molecule). Fixed.
· Symmetry expansion in CIF import is improved. (May not be complete yet)
· Molecule#expand_by_symmetry now returns an array of atom indices instead of IntGroup.
· Molecule#symop_for_transform and transform_for_symop are implemented. The symmetry expansion of CIF import is being reworked, but still incomplete.
· Molecule#is_atom_hidden and AtomRef#hidden, hidden= are implemented, and Molecule#hidden_atoms and hidden_atoms= are made obsolete.
· Molecule#set/get_view_rotation: the sign of the angle is made opposite (left-hand screw in respect to the axis), so that it is consistent with Transform#rotation. This is opposite to the convention of the OpenGL rotator.
· The restriction on the number of bonds (12) is removed (modified so heavily, that it is likely that there is still some bugs left...)
· Include periodicity flags in the 'define unit cell' dialog
· Problem on guessing UFF angle parameter was fixed.
· Fixed a very stupid bug in drawing unit cell.
· Handling of frame-specific cell parameters was very inconsistent. Hopefully fixed, but may be still incomplete.
· Graphite potential in MM/MD gets recalculated much less frequently now.
· Building verlet list was reworked to implement complete search of the periodic lattice points. Still in progress.
· Symmetry operations from the CIF file were not read correctly for hexagonal system. Fixed.
· Mac (only 10.6?): when the graphite display is on, the lighting of the molecule model looks strange. Fixed.
June 19th, 2012· Features of Molecule cell and Molecule box are modified so that the handling of the sigma values of the cell parameters looks more consistent.
· Mbsf format now retains anisotropic parameters and sigma (for crystallographic data)
· Crash during creating bonds when ellipsoid display is on is fixed.
· Ruby: Moleculefit_coordinates is implemented.
· LAMatrixnew, zero, submatrix now accept arguments in 'column,row' order.
· MM forces are updated after 'run(0)'
· Load/save mbsf files were broken when atom type variants were used for atom types with 3 or 4 characters. Fixed.
· The order of parameters in cmd_edit_local_parameter_in_main view dialog was inconsistent. Fixed. Also fixed Ruby exception in UFF guess dialog.
· Moleculetransform, rotate, invert, etc. are now aware of symmetry related atoms. That is, the symmetry operation is updated so that the atoms are also symmetry related after transformation.
· Ruby: AtomRefsymop can now be set from script.
· Ruby: Moleculeamend_by_symmetry is implemented.
· Ruby: Moleculeset(get)_view_translation is now obsolete and replaced by set(get)_view_center.
· The order of the anisotropic thermal parameters is changed to 'b11, b22, b33, b12, b13, b23'. Inconsistency in some of the codes is fixed. TODO: when symmetry expansion is done, the anisotropic thermal parameters should be correctly converted.
· Ruby: Moleculehidden_atoms and Moleculeset_hidden_atoms are implemented.
· The order of columns for MD parameters in the bond/angle/dihedral tables are changed, so that the columns appear in the same order as in the parameter table.
· UFF parameter guess is implemented.
· Moleculeneutralize was not working correctly. Fixed, and Moleculecharge was implemented.
· The load/unload global parameters dialog is sometimes out of the screen. Fixed.

· Various ring structures (cycloalkanes, aromatics) and solvent boxes are accessible from "Open Predefined" menu.
· CIF import is improved, so that bonds including the calculated hydrogen atoms are created by guess.
· Import/export of dcd trajectory files is implemented.
· Creating AMBER input now allows to select between AMBER8 (also for NAMD) and AMBER11 formats.
August 23rd, 2011· Fchk import was broken (enbug in 0.5.6.1); fixed.
· Final compile date/time is now shown in the 'About' window.
· Fix mdcrd import to allow coordinates using full 8 digits (like -123.456 or 1234.567).
· Occasional crash during minimization is fixed.
August 4th, 2011· Crash on running antechamber/parmchk on PPC Mac is (hopefully) fixed.
· Mac: resp and sqm (semiempirial QM calculation invoked by antechamber) caused crash unless gfortran is installed. To fix this, config.h/Makefiles for AmberTools is modified so that gfortran library is statically linked.

· Loading GAMESS dat file now can be interrupted by ESC.
· Disable close box of RubyDialogFrame.
· On importing frcmod, atom type with a single character (like "c") was not recognized properly. Fixed.
