SurveyJS v2.5.13

Released: February 27, 2026

SurveyJS v2.5.13 enables caching for custom asynchronous functions in expressions by default and includes bug fixes and minor enhancements.

Expressions: Caching for Custom Async Functions is Enabled by Default

Introduced in SurveyJS v2.5.10, caching for custom asynchronous functions is now enabled by default. This change enhances performance and should not have any negative impact on existing applications. However, if you want your custom function to perform a server request on every call instead of using the cache, set the useCache option to false when registering the function:

import { registerFunction } from "survey-core";

function myFunc (params) {
  // ...
}

registerFunction({
  name: "foo",
  func: myFunc,
  isAsync: true,
  useCache: false
});
