Changes since v0.7.0:

Urgent Upgrade Notes

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

• Use a single rate limiter for all API types clients.

  Consider adjusting clientConnection.qps and clientConnection.burst if you observe any performance degradation. (#2462, @trasc)

Feature

• Add a column to workload indicating if it is finished (#2615, @highpon)

• Add preempted_workloads_total metric that tracks the number of preemptions issued by a ClusterQueue) (#2538, @vladikkuzn)

• Add the following events for eviction on the workload indicating the reason for eviction:

  • "EvictedDueToPodsReadyTimeout"
  • "EvictedDueToAdmissionCheck"
  • "EvictedDueToClusterQueueStopped"
  • "EvictedDueToInactiveWorkload" (renamed from InactiveWorkload)

  If you were watching for the typed Normal event with InactiveWorkload reason, use EvictedDueToInactiveWorkload reason one instead. (#2376, @mbobrovskyi)

• AdmissionChecks: A workload with a Rejected AdmissionCheck gets deactivated (#2363, @PBundyra)

• Allow stoping admission from a specific LocalQueue. (#2173, @mbobrovskyi)

• CLI: Add stop/resume localqueue commands (#2415, @rainfd)

• CLI: Added Node Labels column on resource flavor list. (#2557, @mbobrovskyi)

  preemption to occur in the same scheduling cycle, even with overlapping
  FlavorResources (#2641, @gabesaba)

• More granular Preemption condition reasons: PriorityReclamation, InCohortReclamation, InCohortFairSharing, InCohortReclaimWhileBorrowing (#2411, @vladikkuzn)

• MultiKueue: Allow for defaulting of the spec.managedBy field for Jobs managed by MultiKueue.
  The defaulting is enabled by the MultiKueueBatchJobWithManagedBy feature-gate. (#2401, @vladikkuzn)

• MultiKueue: Remove remote objects synchronously when the worker cluster is reachable. (#2347, @trasc)

• Fix check that prevents preemptions when a workload requests 0 for a resource that is at nominal or over it. (#2520, @alculquicondor)
• Fix for the scenario when a workload doesn't match some resource flavors due to affinity or taints

• Fixed issue that prevented restoring the startTime and pod template when evicting a batch/v1 Job, if any API errors happened in the process (#2567, @mbobrovskyi)
• MultiKueue: Do not reject a JobSet if the corresponding cluster queue doesn't exist (#2425, @vladikkuzn)
• MultiKueue: Skip garbage collection for disconnected clients which could occasionally result in panic. (#2369, @trasc)
• Show weightedShare in ClusterQueue status.fairSharing even if the value is zero (#2521, @alculquicondor)
• Skip duplicate Tolerations when an admission check introduces a toleration that the job also set. (#2498, @trasc)

Other (Cleanup or Flake)
