# v1.18.0

[Documentation](https://docs.k8s.io)

* Fix concurrent map access panic ([#65327](https://github.com/kubernetes/kubernetes/pull/65327), [@dashpole](https://github.com/dashpole))
    * Don't watch .mount cgroups to reduce number of inotify watches
    * Fix NVML initialization race condition
    * Fix brtfs disk metrics when using a subdirectory of a subvolume

* Flex drivers by default do not produce metrics. Flex plugins can enable metrics collection by setting  the capability 'supportsMetrics' to true. Make sure the file system can support fs stat to produce metrics in this case. ([#67508](https://github.com/kubernetes/kubernetes/pull/67508), [@brahmaroutu](https://github.com/brahmaroutu))

    * Disable the metadata agent for monitored resource construction in logging.
    * Disable timestamp adjustment in logs to optimize performance.
    * Reduce logging agent buffer chunk limit to 512k to optimize performance.

* We change the default attach_detach_controller sync period to 1 minute to reduce the query frequency through cloud provider to check whether volumes are attached or not.  ([#41363](https://github.com/kubernetes/kubernetes/pull/41363), [@jingxu97](https://github.com/jingxu97))

- Reduced GCE log rotation check from 1 hour to every 5 minutes.  Rotation policy is unchanged (new day starts, log file size > 100MB). ([#72062](https://github.com/kubernetes/kubernetes/pull/72062), [@jpbetz](https://github.com/jpbetz))

### Network

- Reduce vSphere volume name to 63 characters ([#100404](https://github.com/kubernetes/kubernetes/pull/100404), [@gnufied](https://github.com/gnufied)) [SIG Storage]

- Reduce event spam during volume operation errors in Portworx in-tree driver ([#135192](https://github.com/kubernetes/kubernetes/pull/135192), [@gohilankit](https://github.com/gohilankit)) [SIG Storage]

### Other (Cleanup or Flake)

- Add flag --lease-reuse-duration-seconds for kube-apiserver to config etcd lease reuse duration. ([#97009](https://github.com/kubernetes/kubernetes/pull/97009), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery and Scalability]
