2.4.0 - Release for Vaadin 14.4

on GitHub

Vaadin Flow 2.4.0 is a feature release of the Java Framework for Vaadin 14.4 that includes a number of new features and enhancements.

New features in 2.4.0:

• In development mode, the webpack devserver is run in a separate thread, improving the server startup time. (Backported from V16 / Flow 3.0)
• Browser automatically reloads when webpack recompiles files in the frontend folder, allowing instant preview of JS and CSS changes. (Backported from V17 / Flow 4.0)
• A new interface HasHelper, for field components that have a helper text feature (e.g. as TextField)

Breaking or behavior changes compared to 2.3

• No public API changes. Only some internal classes related to development mode startup have changed.
• PolymerTemplate: calling setVisible(false) for @Id-mapped components inside the shadow-dom now hides them in browser (#8256) without any workarounds.

All changes since 2.3
