[ANNOUNCE] Kueue v0.13.0 is released

[Yuki Iwai]

Hello kubefolks, we have released Kueue v0.13.0.

Highlights:

• Support for Elastic Jobs (Alpha) 🚀: Kueue now introduces alpha support for dynamically sized jobs. By adding the kueue.x-k8s.io/elastic-job annotation, batch/v1.Job workloads can be resized (scaled up and down) during their execution, a major feature for flexible resource management.
• New MultiKueue Dispatcher API 🌐: This release adds a powerful Dispatcher API for multi-cluster environments. You can now use an external dispatcher to control how workloads are nominated to worker clusters, moving beyond the default all-at-once or incremental strategies for more sophisticated scheduling logic.
• Advanced Scheduling and Fair Sharing ⚖️: The Admission Fair Sharing (AFS) mechanism is now smarter, introducing an "entry penalty" to prevent users from flooding the queue and gaining an unfair advantage. Additionally, preemption candidates are now better ordered to improve fairness.
• Feature Stability and Graduations ✅: Key features have matured, signaling increased stability. ManagedJobNamespaceSelector has graduated to General Availability (GA), and ObjectRetentionPolicies has been promoted to Beta.
• API Stability and Graduations 📈: The Cohort core API has now graduated to Beta.

For more details, please check the release notes and the documentation.

As always, feel free to share your feedback or join the discussions, either via Kueue issues or the wg-batch.

Best,

Yuki
