#   none    - Disable caching entirely
#
# REFERENCE OPTIONS:
#   hard - Strong reference (stays in memory, faster access)
#   soft - Weak reference (can be garbage collected under memory pressure)
#
# CONFIGURATION BREAKDOWN:
#   SourceCacheKey                   - File and RAW model requests (session/hard for consistent file access)

- Fixed a missing behavior where Windows nodes did not implement memory-pressure eviction. ([#122922](https://github.com/kubernetes/kubernetes/pull/122922), [@marosset](https://github.com/marosset)) [SIG Node, Testing and Windows]

- Added Pressure Stall Information (PSI) metrics to node metrics. ([#130701](https://github.com/kubernetes/kubernetes/pull/130701), [@roycaihw](https://github.com/roycaihw)) [SIG Node and Testing]

- Promoted Linux node pressure stall information (PSI) metrics to beta. ([#132822](https://github.com/kubernetes/kubernetes/pull/132822), [@roycaihw](https://github.com/roycaihw)) [SIG Node]

- 'Kubelet added the following Pod failure conditions:
  - `DisruptionTarget` (graceful node shutdown, node pressure eviction)' ([#112360](https://github.com/kubernetes/kubernetes/pull/112360), [@mimowo](https://github.com/mimowo))
- 'Priority and Fairness has introduced a new feature called _borrowing_ that allows an API priority level
