Released: Jun 2, 2026

Updates in v2.5.27

Features

• Dependency Tracking for Expression Questions
  • Introduced a global expressionQuestionTrackDependencies property that controls when Expression question values are recalculated.
  • By default, this setting is false, and Expression questions recalculate whenever any survey value changes. If you set expressionQuestionTrackDependencies to true, Expression questions recalculate only in the following cases:
    • During the initial evaluation.
    • When all expressions are re-evaluated.
    • When a dependent value or property changes.
    • This behavior can improve performance in surveys that contain many Expression questions.

Fixes

• Form Library
  • Dynamic Panel: "Add Panel" button ignores the enableAddPanelIf condition when the panel has 0 entries.
  • Date input shows value from survey.data in disabled (grayed out) text color.
  • Dynamic Panel + Lazy Rendering: Fields of a nested panel do not appear immediately when the parent panel is expanded.
  • Yes/No (Boolean) question in radio button mode inside Dynamic Panel is skipped during keyboard navigation in some panels.
  • Read-only Multi-Select Dropdown (Tag Box) displays the Other option value instead of the Other label.
