==== Pod disruption budget (PDB) unhealthy pod eviction policy (Technology Preview)

With this release, specifying an unhealthy pod eviction policy for pod disruption budgets (PDBs) is available as a Technology Preview feature. This can help evict malfunctioning applications during a node drain.

To use this Technology Preview feature, you must enable the `TechPreviewNoUpgrade` feature set.

[WARNING]
====
Enabling the `TechPreviewNoUpgrade` feature set on your cluster cannot be undone and prevents minor version updates. You should not enable this feature set on production clusters.
