Release v1.9.0

Networking Core Module Release 1.9.0

Welcome to the latest release of Networking module of Kubernetes Fury Distribution maintained by team
SIGHUP.

This is a minor release that updates Calico to version 3.23.2. This update fixes a compatiblity issue with Kuberentes >= 1.21.

Kubernetes 1.21 introduced expiring Service Account Tokens by default and some Calico components where not handling the token renewal gracefully.

Important changes

• Default MTU is not forced anymore and is set to auto, following upstream.
• POD CIDR is not set anymore, Calico has autodetection for clusters created with kubeadm (like KFD clusters).
• Calico 3.23 is not compatible with Kubernetes 1.20 or older.
