# Major Themes

## Action Required

## Notable Features
- Added K8s 1.16 to the test matrix and removed K8s 1.11 from the test matrix.

### Ceph

- The job for detecting the Ceph version can be started with node affinity or tolerations according to the same settings in the Cluster CR as the mons.
- A new CR property `skipUpgradeChecks` has been added, which allows you force an upgrade by skipping daemon checks. Use this at **YOUR OWN RISK**, only if you know what you're doing. To understand Rook's upgrade process of Ceph, read the [upgrade doc](Documentation/ceph-upgrade.html#ceph-version-upgrades).
- Mon Quorum Disaster Recovery guide has been updated to work with the latest Rook and Ceph release.
- A new CRD property `PreservePoolsOnDelete` has been added to Filesystem(fs) and Object Store(os) resources in order to increase protection against data loss. if it is set to `true`, associated pools won't be deleted when the main resource(fs/os) is deleted. Creating again the deleted fs/os with the same name will reuse the preserved pools.
- OSDs:
  - Ceph OSD's admin socket is now placed under Ceph's default system location `/run/ceph`.
  - The on-host log directory for OSDs was set incorrectly to `<dataDirHostPath>/<namespace>/log`;
    fix this to be `<dataDirHostPath>/log/<namespace>`, the same as other daemons.
  - Use the mon configuration database for directory-based OSDs, and do not generate a config
