Support

Vaadin 14 is an LTS (long term support) version, which will be supported for 5 years after the GA (general availability) release. More details of our release model are available on our roadmap page.

Vaadin also provides commercial support and warranty.

New and Noteworthy Since 14.3

  • Field helpers
    • Slot below/above input fields for supplying additional information or content related to the field.
  • Parallelized dev-mode startup
    • Dev mode initialization and webpack build is run in a separate thread and a temporary page telling 'front-end build is ongoing' is shown until compilation is done. This speeds up the deployment time (as Java services like Hibernate can start in parallel) and fixes deployment timeout issues in IDEs
  • Live Reload on frontend changes
    • The browser automatically refreshes when files in the frontend folder are modified, allowing instant preview of JS and CSS changes.

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. If you encounter an issue when using the HTML/JS API of a component or the component renders incorrectly, the problem is likely in the web component. The web component repositories are named like https://github.com/vaadin/vaadin-button
  2. If you encounter an issue when using the Java API of a component, the problem is likely in the Flow integration of the web component. The Flow component integration repositories are named like https://github.com/vaadin/vaadin-button-flow
  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
