# v1.11 Pending Release Notes
|
|
|
|
## Breaking Changes
|
|
|
|
- Removed support for MachineDisruptionBudgets, including settings removed from the CephCluster CR:
|
|
- `manageMachineDisruptionBudgets`
|
|
- `machineDisruptionBudgetNamespace`
|
|
|
|
## Features
|
|
|
|
- Added setting `requireMsgr2` on the CephCluster CR to allow clusters with a kernel of 5.11 or newer
|
|
to fully communicate with msgr2 and disable the msgr1 port. This allows for more flexibility to enable
|
|
msgr2 features such as encryption and compression on the wire.
|
|
- Change `pspEnable` default value to `false` in helm charts, and remove documentation for enabling PSP since the min supported K8s version is 1.21 where PSPs were deprecated.
|
|
- [Bucket notifications and topics](https://rook.io/docs/rook/latest/Storage-Configuration/Object-Storage-RGW/ceph-object-bucket-notifications/)
|
|
for object stores moved to stable from experimental.
|
|
- Introduce [Ceph exporter](https://github.com/rook/rook/blob/master/design/ceph/ceph-exporter.md) as the new source of metrics based on performance counters coming from every Ceph daemon.
|
|
- Added support to enable read affinity for RBD volumes. It leverages the [krbd map options](https://docs.ceph.com/en/latest/man/8/rbd/#kernel-rbd-krbd-options) to allow serving reads from an OSD in proximity to the client, according to OSD locations defined in the CRUSH map and topology labels on nodes.
|
|
- Added support for [multi cluster service](https://github.com/rook/rook/blob/master/design/ceph/multi-cluster-service.md) to export mon and OSD services across multiple clusters with overlapping CIDRs. The clusters should be connected together using MCS API compatible applications like [submariner globalnet](https://submariner.io/getting-started/architecture/globalnet/). This helps establishing rbd mirroring between peer clusters with overlapping CIDRs for disaster recovery scenarios. This feature is supported for Ceph version v17.2.6 or later.
|
|
- Update golang version to (v1.19)[https://github.com/rook/rook/pull/11692] and K8s version to (v1.26.1)[https://github.com/rook/rook/pull/11740]
