 ## diverge branches
 
 on the master branch, delete the changelog (to be filled with new features which
 will also only be pushed to this branch). the release branch will be used for
 bugfix/pointreleases.
 tag the master/development branch as such, so dev packages will be ordered correctly:
 ```
-git tag -s 0.6.9999 -m "this is the beginning of the unreleased development branch which will become 0.7.0 eventually"
+git tag -s 0.7.9999 -m "this is the beginning of the unreleased development branch which will become 0.8.0 eventually"
 ```
