View the full version 16.30 release notes.

• 3D modelling : Software renderer
  • Optimisations applied to the solid rendering methods in W3dShow. Exact benefits are compiler/model dependent.
  • New Show2AutoWork flag added to W3dShow, to automatically determine workspace requirements, rather than relying on limit set via W3dNew. This increases computation time in W3dShow, but eliminates cases where rendering fails due to insufficient workspace.
  • The workspace calculated via the Show2AutoWork flag can be interrogated. This allows calculated workspace size to be tracked during development and the largest noted value used as a W3dNew MAXWORK argument when deployed in a release version.
  • Crossing border facet outline errors in Gouraud shading now only reported once per W3dShow call, rather than for every affected facet.
  • The W3dShow documentation has been expanded, particularly with respect to error conditions.
• Grids
  • Buttons in push button columns now remain capable of generating PushButtonGrid messages when the state of the whole grid is read only, since this state implies "not modifiable" rather than "disabled".
  • New WGridColumnActions routine allows selective control over which multi-cell actions are enabled in a specified column. Allowable actions are search, print, file, clipboard and sorting.
• Operating System Interface
  • IOsDirInfo and IOsFileDate modified to ensure accurate file dates are reported through to the early 22nd century, rather than until 2043 (Windows) or 2038 (Linux/macOS) as previously.
  • Documentation for IOsDirInfo, IOsFileDate and IOsFileTime all expanded w.r.t. 32-bit date/time encoding.
• Resource Editor
  • The "Menu" key is now selectable as a menu item accelerator.
  • A "Select" push button column has been added to the Field List window, allowing the corresponding field to be selected as the current field in the dialog editor.
  • On X Windows, double clicking on a field in the dialog editor's edit window now opens that field's properties dialog, as on Windows.
• 3D model viewer : Line width can now be selected in the wireframe and unlit rendering methods.
• Help editor : Obsolete features relating to HTML/Javascript help file set creation have been removed, notably the "legacy" format. The latter is no longer needed following resolution of the last remaining issue in the newer "unified" format at 16.20a.
