## Changelog since v1.3.5

### Other notable changes

* Addresses vSphere Volume Attach limits ([#29881](https://github.com/kubernetes/kubernetes/pull/29881), [@dagnello](https://github.com/dagnello))
* Increase request timeout based on termination grace period ([#31275](https://github.com/kubernetes/kubernetes/pull/31275), [@dims](https://github.com/dims))

bumped version of golang it is compiled with to go1.18, which introduced significant changes to its garbage collection algorithm. As a result, we observed an increase in memory usage for kube-apiserver in larger an heavily loaded clusters up to ~25% (with the benefit of API call latencies drop by up to 10x on 99th percentiles). If the memory increase is not acceptable for you you can mitigate by setting GOGC env variable (for our tests using GOGC=63 brings memory usage back to original value, although...

     * * **Unreachable IP addresses.** If the URL's host has multiple IP addresses,
     *   failure to reach any individual IP address doesn't fail the overall request. This can
     *   increase availability of multi-homed services.
     *
     * * **Stale pooled connections.** The [ConnectionPool] reuses sockets
     *   to decrease request latency, but these connections will occasionally time out.
     *

    expands HTTP/2 support to older Android devices that have Google Play
    Services.
 *  New: Consider all routes when looking for candidate coalesced connections.
    This increases the likelihood that HTTP/2 connections will be shared.
 *  New: Authentication challenges and credentials now use a charset. Use this in
    your authenticator to support user names and passwords with non-ASCII
    characters.

* fix the create azure file pvc failure if there is no storage account in current resource group ([#56557](https://github.com/kubernetes/kubernetes/pull/56557), [@andyzhangx](https://github.com/andyzhangx))
* Increase allowed lag for ssh key sync loop in tunneler to allow for one failure ([#60068](https://github.com/kubernetes/kubernetes/pull/60068), [@wojtek-t](https://github.com/wojtek-t))

* Creating LoadBalancer Service with "None" ClusterIP is no longer possible ([#33274](https://github.com/kubernetes/kubernetes/pull/33274), [@nebril](https://github.com/nebril))
* Increase timeout for federated ingress test. ([#33610](https://github.com/kubernetes/kubernetes/pull/33610), [@quinton-hoole](https://github.com/quinton-hoole))

* In GCE with COS, increase TasksMax for Docker service to raise cap on number of threads/processes used by containers. ([#51986](https://github.com/kubernetes/kubernetes/pull/51986), [@yujuhong](https://github.com/yujuhong))

- Kube-apiserver: gzip compression switched from level 4 to level 1 to improve large list call latencies in exchange for higher network bandwidth usage (10-50% higher). This increases the headroom before very large unpaged list calls exceed request timeout limits.
