On December 2nd, Spring Cloud released the first release of Spring Boot 2.6 support. The release number is 2021.0.0, and codename is Jubilee.
Before we get into the details of the update, the most important point is that Spring Boot for version 2021.0.0 starts at 2.6.1, so don’t use version 2.6.0 when upgrading.
Ok, let’s take a look at this version with DD.
