## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

 - ACTION REQUIRED for custom scheduler plugin developers:
  `PodEligibleToPreemptOthers` in the `preemption` interface gets `ctx` in the parameters.
  Please change your plugins' implementation accordingly. ([#126465](https://github.com/kubernetes/kubernetes/pull/126465), [@googs1025](https://github.com/googs1025)) [SIG Scheduling]
