Vaadin 7 extended maintenance

Now available as an optional add-on for Prime and Ultimate subscribers.

Vaadin 7.7.17 was the last public open-source version of the Vaadin 7 framework. We guaranteed 5 years of maintenance from the release date. Official support for Vaadin 7 ended in February 2019.

Vaadin Prime customers can continue to get support up until 2029 by purchasing Extended Maintenance. Vaadin will fix issues in the framework and widgets, ensuring that your applications and end-customers don’t feel any negative impact.

Scope

  • Vaadin 7 Core framework.
  • All Vaadin 7-specific Pro add-ons (for example, Touchkit for Vaadin 7).
  • All official Core Add-ons (for example CDI, Spring, ContextMenu, etc.).
  • New feature development for Vaadin 7 (Enterprise subscribers only). Enterprise customers can use Expert on Demand (EoD) support hours for this.

Common use-cases

  • Your internal web framework that powers your critical business web applications is built on Vaadin 7. 
  • You have a customer-facing web application built on Vaadin 7 and still have binding support agreements with your customers. 
  • The cost of migrating to a more recent Vaadin version is more than the cost of extended maintenance.

Types of maintenance tasks

The Vaadin support team will perform two types of maintenance tasks:

  • Proactive tasks
    • Automated integration testing on Vaadin 7-supported browsers.
    • 3rd party library monitoring for security alerts etc.
    • Security impact monitoring of any new features added to Vaadin 7 (through EoD etc.). The security impact is reviewed through the normal review processes.
  • Reactive maintenance tasks
    • Responding to bug fix and warranty priorities for Vaadin 7.
    • Responding to Expert Chat requests for Vaadin 7-related issues.

Communication

  • If Vaadin receives a report for a security flaw, Vaadin will fix the issue, and then communicate the incident to all affected customers (through a private mailing list).
  • Expert Chat can be used for Vaadin 7-related communication.

Bug Fixes and feature releases in the Framework since version 7.7.17

Under the extended maintenance service, Vaadin has already released the following versions to our customers:

Vaadin 7.7.42

  • Added read-only support to Grid. This allows disabling editing features in an otherwise editable Grid while still retaining scrolling. Use existing API method Grid.setReadOnly(true).
  • Enabled dependency convergence enforcement in Vaadin 7 to mitigate transitive dependency mismatches.
  • Internal test fixes

Vaadin 7.7.41

  • Fixed a regression which caused issues if the syncId check was disabled
  • Added the possibility to reorder UIProviders
  • Modified the Framework 7 project itself to compile with Java 11, note applications made with Vaadin 7 do not require Java 11, they still work with Java 7 or newer (Java 17). This is more an internal improvement ensuring our infrastructure being future proof.
  • License updated to VCL-2
  • Fixed a version mismatch for the license checker being used
  • Test fixes

Vaadin 7.7.40

  • Fixed an issue where compile-time license checking would fail on CI servers with release-only license files.
