One of the biggest update in this release is the configuration optimization. We discarded the old configuration and introduced a new one. Currently, the new configuration has been updated to the master branch of samples (corresponding to latest dubbo-go 3.0), and there are introductions and detailed examples on the our website dubbogo.github.
-
