Non 1.26 specific but still relevant work

Cluster API support

MicroK8s bootstrap and control plane CAPI providers for AMD64 and ARM64. Clusters deployed with Cluster API benefit from features such as; automatic and frictionless patch-level upgrades, a comprehensive set of addons to ease the cluster deployment and operations, as well as the ability to deploy any Kubernetes version with ease.

EKS-D

EKS-D is a Kubernetes distribution with extended support used by Amazon Elastic Kubernetes Service (EKS). New tracks have been introduced to accommodate all EKS-D releases: 1.22, 1.23 and 1.24. For example, get the 1.24 release with:

snap install microk8s --classic --channel=1.24-eksd/stable

The EKS-D tracks bundle the extra patches from the EKS Distro as well as various addons for storage and authentication, offering a similar experience to EKS with all the added benefits of MicroK8s.
