Vaadin 7 extended maintenance
FACT SHEET
Vaadin 7.7.17 was the last public open-source version of the Vaadin 7 framework. Vaadin guarantees 5 years of maintenance from the release date of long-term release (LTS) versions. Official support for Vaadin 7 ended in February 2019.
Vaadin Prime subscription customers get access to Vaadin 7 version that extends the support for up until 2029. 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.
