Todd, we didn't change the development space. We changed only the default organisation name to TBASE.
As far as I understood this docu, it is optional.
Installation docu
Optional:
If you want to change the name of the development space from the default DEV: Set the DEV_SPACE property of the di-dev-space resource to the new name, for example: resources: - name: di-dev-space properties: DEV_SPACE: MYSPACE
