## Before Upgrading

Consider the following changes, limitations, and guidelines before you upgrade:

### **API Machinery**

* Disable session affinity for internal kubernetes service - Backport of [#56690](https://github.com/kubernetes/kubernetes/pull/56690) to 1.10 release branch ([#65177](https://github.com/kubernetes/kubernetes/pull/65177), [@afritzler](https://github.com/afritzler))



# v1.10.5

pkg syscall (freebsd-riscv64), type Flock_t struct, Sysid int32 #53466
pkg syscall (freebsd-riscv64), type Flock_t struct, Type int16 #53466
pkg syscall (freebsd-riscv64), type Flock_t struct, Whence int16 #53466
pkg syscall (freebsd-riscv64), type Fsid struct #53466
pkg syscall (freebsd-riscv64), type Fsid struct, Val [2]int32 #53466
pkg syscall (freebsd-riscv64), type ICMPv6Filter struct #53466

* Upgrade golang.org/x/net image to release-branch.go1.10 ([#70663](https://github.com/kubernetes/kubernetes/pull/70663), [@wenjiaswe](https://github.com/wenjiaswe))

- Featuregate AllowInsecureBackendProxy graduates to GA and unconditionally enabled. ([#99658](https://github.com/kubernetes/kubernetes/pull/99658), [@deads2k](https://github.com/deads2k))
- Increase timeout for pod lifecycle test to reach pod status=ready ([#96691](https://github.com/kubernetes/kubernetes/pull/96691), [@hh](https://github.com/hh))

- Fix throughput when scheduling daemonset pods to reach 300 pods/s, if the configured qps allows it. ([#124753](https://github.com/kubernetes/kubernetes/pull/124753), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- Kubeadm: ensured waiting for apiserver uses a local client that doesn't reach to the control plane endpoint and instead reaches directly to the local API server endpoint. ([#134269](https://github.com/kubernetes/kubernetes/pull/134269), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

  When adding links which point to resources within git repositories, like
  KEPs or supporting documentation, please reference a specific commit and avoid
  linking directly to the master branch. This ensures that links reference a
  specific point in time, rather than a document that may change over time.
