in many forms are very welcome, particularly if you'd like to help with user documentation or website developement.

Highlights (tldr)

• Adds molecular surfaces, solvent-accessible, and solvent-excluded surfaces
• Adds support for a range of partial charge models, including coloring electrostatic potentials on surfaces.
  • This includes writing Python scripts to assign atomic charges or electrostatic potential
• Adds improved hydrogen-bond, chalcogen, and halogen bond rendering.
• Add improved close-contact and salt-bridge rendering
• Significantly improves interface translation, properly loading translation files, and including a dialog to choose your preferred user interface language (thanks to @ovari for significant help)
  • Includes English, Hungarian, Serbian, Esperanto, Portuguese, Turkish, German, Georgian, French, and Japanese translations with at least 45% coverage. Anyone can help via Weblate
• Now supports VTK-9 and Mac and Windows packages are updated to use Qt 5.15.
