Hi, For me the biggest issues regarding Camel 4 have been when Karavan VS Code extension updated itself to 4.0.0. I'm not sure things related to Karavan are discussed in the blog post but here's couple things we've encountered.
In short, if you use Karavan 4.x.x to open a route which has been designed with the 3.x.x version, in many cases the route breaks as the designer removes parts of it. I think the yaml schema has changed a bit between the releases and the editor only supports the latest version with no backward compatibility. In addition to that, the latest Karavan editor has some issues UI issues (scrolling the property panel doesn't work as it should, some textboxes are broken). We decided to downgrade the Karavan back to 3.x.x even though we updated Camel to 4.x.x. The Camel 4 itself has been a rock solid release. No issues. pe 6. lokak. 2023 klo 11.52 ski n (raymondmees...@gmail.com) kirjoitti: > Sure happy to give feedback.
