Qualitia supports upgrade from v3.14. In case you are using prior version of Qualitia WebDriver, please upgrade to v3.14 first and then upgrade to Qualitia for Web and Mobile v4.1.5.

In case your MySQL database server is on Linux machine, you must first upgrade to the 4.1.6 before upgrading to the latest version of Qualitia.

In order to optimize execution performance for non-browser test cases, Qualitia now launches the browser only on the OpenURL action. This might cause failing test cases with any browser-based actions used before OpenURL in 4.1.x and above.
Qualitia users must use the browser-based actions such as MaximizeBrowser and so on after the OpenURL action.
