I am very confused with all new vaadin versions upcoming. In few month ago Vaadin 10 was just released and now there are two others versions 11 and 12.
Are they declination of the vaadin 10 framework with the same technical base ? Like others versions : 8.0 , 8.1 …
The versioning scheme changed with the jump from 8 to 10. In broad terms, 11 can be thought of 10.1, 12 as 10.2 and so on. Take a look at https://vaadin.com/roadmap and https://vaadin.com/blog/the-revaadin-platform for more information.
