• Improved ribbon and tube rendering of cyclic structures • A format error is no longer incorrectly reported when loading certain valid mmCIF files.

• Make video recordings of animations within the program • Load PDB-format coordinates from your own external scripts • User interface polish

• Scenes in custom animations can optionally spin or oscillate. • The View Editor window can be set to open when the program launches. • View Editor visibility can be toggled by a toolbar button. • Updates for MacOS Sequoia • Bug Fixes and UI improvements

• A unified View Editor window provides a central location to make adjustments to the visual presentation. • The model-traversal animation can now optionally center each model as it is shown. • Bug fixes and performance improvements.

• A new animation sequentially displays molecular models at a user-adjustable speed • Atom label formats that include single-letter amino acid codes were added • When reading PDB/PDBQT files, model names are retrieved from lines of the form "REMARK Name = ..." if present • When reading PDB/PDBQT files, docking scores are retrieved from lines of the form "REMARK VINA RESULT: ...", and the score is appended to the model name • Multiple bug fixes and UI improvements

• Fixed a bug that could potentially cause a hang or crash when playing a custom animation • Fixed a bug preventing a saved scene from appearing when transitioning from an blank window • XYZ coordinate format can now be read

• Faster solvent-excluded surface generation • Improved rendering of multiple translucent surfaces • Commands in the object browser context menu to hide or show hydrogens • Improved animation performance and transitions • Additional optional toolbar buttons • Other bug fixes and user interface improvements

• New animation features allow creation of complex custom animations for presentations and videos. • The color assigned to Uracil in the "Residue" color scheme was changed to improve visual contrast. • Multiple performance and user interface improvements. • Improved responsiveness when canceling long-running operations. • Fixed a bug that could potentially cause a crash when loading V3000 SDF/MOL files containing nonspecific atom types.

• Atom label positions are now adjustable using the Object Editor, and an additional label format is available. • Coordinate files in PDBQT format can now be read. • A bug causing torsion angle measurements to be saved incorrectly was fixed. • The performance of the Oscillate command is improved.

• Simple nucleic acid representations • An "Oscillate" command to continuously rock a structure back and forth • Additional recognized terms for text selection of atoms • More items included on the default toolbar • Improved performance • User interface adjustments

User interface bug fixes and improvements

• The radii of bond, ball-stick, tube, chain trace and ribbon representations are now adjustable. • The color assigned to any chemical element can now be changed in the "Element" color scheme using the Object Editor. • All colors in the "Secondary Structure" color scheme can now be changed. • The translucency of surfaces is now adjustable using a slider in the Object Editor instead of using the system color panel. • There are now menu items and keyboard shortcuts for adjusting the depth and position of the view frustum ("slab"). • Optional undo/redo toolbar buttons are now available. • Some minor user interface bugs have been resolved. • The font used for labels is now Helvetica Bold rather than Helvetica. • The initial window size has been increased.
