Is there any information which clean up rules in the version 9.0 will be added? The Issue "TW-8717 Add more build cleanup conditions" has fix version 9.0.
We need rules in style
* A build with a specific pattern string in the version number (eg "alpha" - beta and final would thus not be deleted - that would be our main application) and/or
* A build with a special tag
A workaround / alterative would be the Issue "TW-19949 pin a running build"
