After upgrade to Vaadin 24.4.0.alpha3 now it asks me about the license:
c.v.pro.licensechecker.LicenseChecker : Opening system browser to validate license. If the browser is not opened, please open [URL] manually
For CI/CD build servers, you need to download a server license key, which can only be used for production builds. You can download a server license key from https://vaadin.com/myaccount/licenses.
If you are working offline in development mode, please visit [URL] for an offline development mode license.
In my application I only use free Vaadin components.
Has something changed, and is there no longer a free version of Vaadin available?
