What's New in SurveyJS v3.0

Bug Fixes

Form Library

  • [survey-core] Memory leak: TOCModel leaves an anonymous scroll listener attached to the survey root element (#12003)
  • [survey-*-ui] Memory leak: Scroll listeners retain replaced survey models because beforeDestroySurveyElement() is never called (#12004)
  • Topmost question is hidden when navigating to the next page (#11974)
  • Dynamic Panel: "Next" button caption does not update when the survey locale changes (#11979)
  • [Vue 3] Dynamic Panel: Fields in the next panel remain hidden even when values in the previous panel satisfy their visibility conditions (#11978)
  • defaultValueExpression incorrectly overrides a value explicitly set in survey.data (#11985)
  • Specialized question type with inheritBaseProps: true: toJSON() omits description and requiredErrorText when they are absent from questionJSON (#11973)
