* Fix initial exec terminal dimensions. ([#51126](https://github.com/kubernetes/kubernetes/pull/51126), [@chen-anders](https://github.com/chen-anders))
* vSphere: Fix attach volume failing on the first try. ([#51218](https://github.com/kubernetes/kubernetes/pull/51218), [@BaluDontu](https://github.com/BaluDontu))



# v1.6.9

* Fixed regression in initial kubectl exec terminal dimensions ([#51127](https://github.com/kubernetes/kubernetes/pull/51127), [@chen-anders](https://github.com/chen-anders))

### Bug or Regression

- Fixed `threadSafeMap` high memory usage caused by indices that have churn of high-cardinality keys. E.g. namespaces ([#88007](https://github.com/kubernetes/kubernetes/pull/88007), [@patrickshan](https://github.com/patrickshan)) [SIG API Machinery]

*   [beta] Flag `--chunk-size={SIZE}` is added to `kubectl get` to customize the number of results returned in large lists of resources. This reduces the perceived latency of managing large clusters because the server returns the first set of results to the client much more...

    * 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.
