  -Note that the branch name is *not* the same any of the eventual tag names (eg `isis-1.16.0` or `simpleapp-archetype-1.16.0`).
  +Note that the branch name is *not* the same any of the eventual tag names (eg `isis-2.0.0` or `simpleapp-archetype-2.0.0`).
   
   If they did have the same name, then what would happen is that the `maven-release-plugin` would checkout the (HEAD of the) branch and thus upload a SNAPSHOT to the snapshot repository.
   What it should of course do is checkout the tag and then upload that to the release staging repository.

negative.code: If it has not, make the change.
  
  Double check that the version number of the core POM (`core/pom.xml`) should reflect the branch name that you are now on.
  For example, if releasing version `2.0.0`, the POM should read:
  
  [source,xml]
  ----
  <groupId>org.apache.isis.core</groupId>
  <artifactId>isis</artifactId>
  <version>2.0.0-SNAPSHOT</version>
  ----
  
  Also, check that there are no snapshot dependencies:
