Change Log

SNAP 2.6.2 - Released 8/16/2018

  • The Maximum Concurrent Jobs property in Configuration Tool can now be set to 10240 for very large clusters.
  • The Version Control tool bar in the main tool bar may now be hidden through the right-click pop-up menu on the main toolbar.
  • The value based comparison logic has been updated to handle comparing categories from the Navigator better. Refreshing the dialog will find new components in the category, and category node components will be included in the comparison.
  • An issue was resolved that caused an unsupported "Loops" category to appear as an option in the 2D View Insertion Tool menu.
  • A series of standard editors provided by the core API have been updated to allow context selection.
  • The undo / redo logic for editing the legacy comment field for components has been updated to ensure changes may be undone and redone.
  • The ASCII view and validation display window now allow double clicking on context values to open the associated editors.
  • An issue was resolved in the "Trim Excess Canvas" 2D View feature that caused explicitly placed connection segments and points to be incorrectly translated.
  • The view component copy/paste logic has been updated to ensure that when an open view is copied between models, all of the drawn elements of that view are included if possible. Also, undoing a paste operation on a view will close the view.
  • The view component was updated to resolve an issue where undoing a change to the background color of an open view would not change the property view value.
