Special Note for 1.7+ Ops Manager Deployments
The 1.7, 1.8, 1.9, and 1.10 release lines of Ops Manager include a feature that allows tile stemcells to “float”, which lets Operators update their Ops Manager deployment once rather than installing all new Services product releases. If you upgrade one Service tile in Ops Manager with the newly released stemcell, all tiles with the "float" enabled will automatically upgrade. For more information about the floating stemcell feature, refer to this document.
