New and Noteworthy

Here are the highlighted new and improved features in this maintenance release.

Flow 6.0.2

• Fixes:

  • ⧉ Write generated theme file to the generated folder. PR:10262. Ticket:10030

  • ⧉ Support Java 16 for production build (#10231). PR:10232. Ticket:10115

    Updates bytebuddy dependency from 1.10.9 -> 1.10.21

  • ⧉ Fix shortcuts when listenOn is a dialog (#10264). PR:10265

    This makes it possible for a component to specify a client side only element that should be used for listening keydown events on when the component is setup as the listenOn target for a Shortcut. This is needed for components like Vaadin Dialog which transport the dialog contents inside an overlay that only exists on the client side and thus breaks shortcut event handling. Related to #7799, vaadin/vaadin-dialog#229

  • ⧉ Revert "Execute error handling as a last action in message handler" (#10254). PR:10258

  • ⧉ Cache stats.json file loaded from class path which improves the performance by not opening too many stats.json files under the load (#10252). PR:10244. Ticket:10116. Special thanks to @knoobie for contributing this.

Reporting Issues

We appreciate if you try to find the most relevant repository to report the issue in. If it is not obvious which project to add issues to, you are always welcome to report any issue at https://github.com/vaadin/platform/issues.

A few rules of thumb will help you and us in finding the correct repository for the issue:

1. Bug tickets and enhancement requests that are specific to a certain Vaadin component should be posted in the component's Web Component repostory (e.g. https://github.com/vaadin/vaadin-button for Button).
2. Issues that are not component-specific (e.g. requests for new components) or encompass multiple components should be posted in vaadin-flow-components repository.
3. If you encounter an issue with Flow which does not seem to be related to a specific component, the problem is likely in Flow itself. The Flow repository is https://github.com/vaadin/flow
4. If you encounter an issue with Designer, the repository is https://github.com/vaadin/designer
5. If you encounter an issue with TestBench, the repository is https://github.com/vaadin/testbench
