v2.10.0 is released

New in this release - Simulink

  • Added support for .sldd files (details).
  • Some blocks with custom mask drawing code had their background and foreground colors set to white. Because DiffPlug can't read all custom mask code, white-on-white is invisible, so the foreground color is now drawn as grey for these cases.
  • When the label of a constant block is too long to fit, DiffPlug tries shrinking the font by 1 or 2 points.

Fixed in this release - Simulink

  • Stateflow blocks whose ports have been reordered are now drawn in the correct position - no more unnecessary wire bends.
  • Various bugs around drag-and-drop on the DiffList have been fixed.
