 ## 2.7.0-rc.0 / 2019-01-18
 
 This release adds experimental support for disk size based retention. To accomodate that we are deprecating the flag `storage.tsdb.retention` in favour of `storage.tsdb.retention.time`. We print a warning if the flag is in use, but it will function without breaking until Prometheus 3.0.
