New and Noteworthy

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

Vaadin Flow (2.5.3)

• Fixes:

  • ⧉ Compare file content from stream. PR:10640

    Compare jar file content and existing target file content before writing to disk.

  • ⧉ Do not override user pinned versions with pnpm. PR:10635. Ticket:9793

    Any user defined (package.json / NpmPackage-annotation) versions will not be overridden by based on the platform versions (versions.json file). This means that the users will have to remember to also remove their pins after those are not needed anymore or they will stay on using old versions, which is the same as with Maven overrides.

  • ⧉ Avoid log an error if frontend tool can't be found. PR:10631. Ticket:9212

  • ⧉ Upper and lower case drive works in build. PR:10638. Ticket:8959

    Update the directory-maven-plugin to not fail the build on windows when the CWD drive letter is lower case.

  • ⧉ Log webpack output on failure. PR:10628. Ticket:7472

    Log as error any output from webpack when webpack exits prematurely without success/failure.

Vaadin Components(14.5.3)

Changes in vaadin-grid-flow

• Warranty Fixes:
  • ⧉ Allow joining columns over multiple headers (#775). PR:786. Ticket:1928

Changes in vaadin-radio-button-flow

• Fixes:

  • ⧉ Change enabled state of radio-buttons when enabled state of radio-button-group changes (#774). PR:801

    ItemEnableProvider is no longer ignored when re-enabling a disabled radio-button-group

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
