Feature Gates (removed)
This page contains list of feature gates that have been removed. The information on this page is for reference. A removed feature gate is different from a GA'ed or deprecated one in that a removed one is no longer recognized as a valid feature gate. However, a GA'ed or a deprecated feature gate is still recognized by the corresponding Kubernetes components although they are unable to cause any behavior differences in a cluster.
For feature gates that are still recognized by the Kubernetes components, please refer to the Alpha/Beta feature gate table or the Graduated/Deprecated feature gate table
Feature gates that are removed
In the following table:
- The "From" column contains the Kubernetes release when a feature is introduced or its release stage is changed.
- The "To" column, if not empty, contains the last Kubernetes release in which you can still use a feature gate. If the feature stage is either "Deprecated" or "GA", the "To" column is the Kubernetes release when the feature is removed.
