SurveyJS v2.5.27

Released: June 2, 2026

This release includes bug fixes, minor enhancements, and a new performance-related feature for Expression questions: dependency tracking for value recalculation control. Alongside it, SurveyJS v3.0 Beta is available as a major upcoming milestone that introduces a unified styling system across products, a redesigned Dashboard, enhanced PDF customization, and a no-code editor for Survey Creator UI and behavior.

What's New in SurveyJS v3.0 Beta

Dependency Tracking for Expression Questions

SurveyJS v2.5.27 introduces 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.

import { settings } from "survey-core";

settings.expressionQuestionTrackDependencies = true;

Expressions that use parameterless functions or functions whose parameters do not reference survey values recalculate on every value change, regardless of the expressionQuestionTrackDependencies setting.
