+Kubernetes API Version: 1.18.12
+
+**Important Information:**
+
+- The Kubernetes Python client versioning scheme has changed. The version numbers used till Kubernetes Python Client v12.y.z lagged behind the actual Kubernetes minor version numbers. From this release, the client is moving a version format `vY.Z.P` where `Y` and `Z` are respectively from the Kubernetes version `v1.Y.Z` and `P` would incremented due to changes on the Python client side itself. Ref: https://github.com/kubernetes-client/python/issues/1244
+- Python 2 had reached [End of Life](https://www.python.org/doc/sunset-python-2/) on January 1, 2020. The Kubernetes Python Client has dropped support for Python 2 from this release (v18.0.0) and will no longer provide support to older clients as per the [Kubernetes support policy](https://kubernetes.io/docs/setup/release/version-skew-policy/#supported-versions).
+
+**Deprecations:**
+- The following deprecated APIs can no longer be served:
+  - All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
+  - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead
+  - `networkpolicies` resources under `extensions/v1beta1` - use `networking.k8s.io/v1` instead
+  - `podsecuritypolicies` resources under `extensions/v1beta1` - use `policy/v1beta1` instead ([#85903](https://github.com/kubernetes/kubernetes/pull/85903), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps, Cluster Lifecycle, Instrumentation and Testing]
+
+**API Change:**
+- Fix bug in reflector that couldn't recover from "Too large resource version" errors ([#92537](https://github.com/kubernetes/kubernetes/pull/92537), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]
+- Fixed: log timestamps now include trailing zeros to maintain a fixed width ([#91207](https://github.com/kubernetes/kubernetes/pull/91207), [@iamchuckss](https://github.com/iamchuckss)) [SIG Apps and Node]
+- Fixed: log timestamps now include trailing zeros to maintain a fixed width ([#91207](https://github.com/kubernetes/kubernetes/pull/91207), [@iamchuckss](https://github.com/iamchuckss)) [SIG Apps and Node]
+- Resolve regression in metadata.managedFields handling in update/patch requests submitted by older API clients ([#92007](https://github.com/kubernetes/kubernetes/pull/92007), [@apelisse](https://github.com/apelisse)) [SIG API Machinery and Testing]
+- A new IngressClass resource has been added to enable better Ingress configuration. ([#88509](https://github.com/kubernetes/kubernetes/pull/88509), [@robscott](https://github.com/robscott)) [SIG API Machinery, Apps, CLI, Network, Node and Testing]
+- The CSIDriver API has graduated to storage.k8s.io/v1, and is now available for use. ([#84814](https://github.com/kubernetes/kubernetes/pull/84814), [@huffmanca](https://github.com/huffmanca)) [SIG Storage]
+- autoscaling/v2beta2 HorizontalPodAutoscaler added a `spec.behavior` field that allows scale behavior to be configured. Behaviors are specified separately for scaling up and down. In each direction a stabilization window can be specified as well as a list of policies and how to select amongst them. Policies can limit the absolute number of pods added or removed, or the percentage of pods added or removed. ([#74525](https://github.com/kubernetes/kubernetes/pull/74525), [@gliush](https://github.com/gliush)) [SIG API Machinery, Apps, Autoscaling and CLI]
+- Ingress:
+  - `spec.ingressClassName` replaces the deprecated `kubernetes.io/ingress.class` annotation, and allows associating an Ingress object with a particular controller.
+  - path definitions added a `pathType` field to allow indicating how the specified path should be matched against incoming requests. Valid values are `Exact`, `Prefix`, and `ImplementationSpecific` ([#88587](https://github.com/kubernetes/kubernetes/pull/88587), [@cmluciano](https://github.com/cmluciano)) [SIG Apps, Cluster Lifecycle and Network]

([#88488](https://github.com/kubernetes/kubernetes/pull/88488), [@gnufied](https://github.com/gnufied)) [SIG  Storage]

+- The beta feature `ServerSideApply` enables tracking and managing changed fields for all new objects, which means there will be `managedFields` in `metadata` with the list of managers and their owned fields.
+- The alpha feature `ServiceAccountIssuerDiscovery` enables publishing OIDC discovery information and service account token verification keys at `/.well-known/openid-configuration` and `/openid/v1/jwks` endpoints by API servers configured to issue service account tokens.

+- CustomResourceDefinition schemas that use `x-kubernetes-list-map-keys` to specify properties that uniquely identify list items must make those properties required or have a default value, to ensure those properties are present for all list items. See https://kubernetes.io/docs/reference/using-api/api-concepts/#merge-strategy for details.

+## Homogenizing the Kubernetes Python Client versions
+
+The client releases v12 and before following a versioning schema where the major version was 4 integer positions behind the Kubernetes minor on which the client is based on. For example, v12.0.0 is based on Kubernetes v1.16, v11.0.0 is based on Kubernetes v1.15 and so on.
+
+This created a lot of confusion tracking two different version numbers for each client release. It was decided to homogenize the version scheme starting from the Kubernetes Python client based on Kubernetes v1.17. The versioning scheme of the client from this release would be vY.Z.P where Y and Z are the Kubernetes minor and patch release numbers from Kubernets v1.Y.Z and P is the client specific patch release numbers to accomodate changes and fixes done specifically to the client.
