Release Notes

Changes from v1.8.1 to v1.9.0

IMPORTANT: This version of Diego subtracts the maximum size of the cell’s download cache from the advertised disk capacity of the cells in order to guard against cases where the cell VMs actually run out of ephemeral disk space on account of competition from instance and system disk usage. This more conservative advertised capacity may result in an increase in placement errors due to insufficient resources in environments that have relatively small disks provisioned. Operators may still configure this capacity manually via the diego.executor.disk_capacity_mb property.
