Vaadin Studio pre-release

Release estimated: Apr 15

Vaadin Studio is a VS Code based code-first user interface editor. It is built for editing Lit templates in a visual way, where you are always in charge of your code, while seeing the UI live.

• Live preview: See the UI while you edit the Lit template. Sub 100ms refresh rate shows UI changes while you type.
• Two-way cursor sync: Never lose the place, when you can click UI or code and see where you are in the other.

When you write the code in Studio, features (like the two above) are free. We'll add later on advanced editors that will generate code for you, those are available for subscribers.

Vaadin 22 LTS

Release estimated: Dec 1

No new features are planned for Vaadin 22. Instead, we focus solely in testing and quality. 

Plan is to declare Vaadin 22 as Long Term Supported, meaning that it will have support and maintenance available for up to 15 years.

Upgrade from Vaadin 14 LTS should be easy as there are no significant APIs that would be removed in this release.

Vaadin 22.1

• Collaboration Engine: Real-time collaboration support with Fusion and TypeScript.
  
  
  

Release model

Vaadin 14.x

Vaadin 14 and the following minors 14.x provide a stable platform to build Progressive Web Applications on and is the default choice for new applications. Most of our development effort goes towards 14.x with a focus on new features in addition to improving the developer experience based on our community's feedback. We focus on making it faster to develop, test, and debug your Vaadin web applications. As the 14.x series is an LTS, it has up to 15 years of support ahead.

We release backward compatible 14.x versions whenever a consistent feature set is completed.

We recommended this version for most users who are building production applications. For applications that require great IE11 support, we recommend Vaadin 8.

Vaadin 15+

Vaadin 15 and the following majors are incremental steps towards the next LTS release. Many of the features included Vaadin 15+ will also be released as backwards compatible features with the latest LTS, 14.x.

We release a new major version of Vaadin every 3 months. These releases are supported for 4 months.

Roughly every two years, we release a Long Term Support (LTS) version. We develop significant new features in the non-LTS releases, and when the features have matured and are ready for general use, we release an LTS version. The next LTS is planned to be released in Dec 2021.

We recommend this version for early adopters who are eager to explore the new features and want to have a say in the future direction of the product.

Support

We support LTS versions for 5 years, and for 15 years for our Enterprise customers. All fixes are made to the latest released version.

With the warranty service, available to Prime and Enterprise customers, we fix issues you come across for all currently supported versions.

* The support for Vaadin 8 includes the Vaadin 7 compatibility classes even though Vaadin 7 support has ended.
