- In the event that more than one IngressClass is designated "default", the DefaultIngressClass admission controller will choose one rather than fail.

- [`KT-62335`](https://youtrack.jetbrains.com/issue/KT-62335) Improve debuggability of code generator crashes
- [`KT-61165`](https://youtrack.jetbrains.com/issue/KT-61165) More than one overridden descriptor declares a default value for 'cause: Throwable?'. As the compiler can not make sure these values agree, this is not allowed

  the correct number of rules, rather than being off by one.
  
  Fixed multiple iptables proxy regressions introduced in 1.22:
  
    - When using Services with SessionAffinity, client affinity for an
      endpoint now gets broken when that endpoint becomes non-ready
      (rather than continuing until the endpoint is fully deleted).
  

### Bug or Regression

- Fixed a regression since 1.27.0 in scheduler framework when running score plugins. 
  The `skippedScorePlugins` number might be greater than `enabledScorePlugins`, 
  so when initializing a slice the cap(len(skippedScorePlugins) - len(enabledScorePlugins)) is negative, 

- Support more than 100 disk mounts on Windows (#105673, @andyzhangx) [SIG Storage and Windows]
- The --leader-elect* CLI args are now honored correctly in scheduler. (#106130, @Huang-Wei) [SIG Scheduling]
- The kube-proxy sync_proxy_rules_iptables_total metric now gives
  the correct number of rules, rather than being off by one.
  

has now graduated to Beta.
This allows the kubelet to dynamically retrieve credentials for a container image registry
using exec plugins, rather than storing credentials on the node's filesystem.
