Linkerd, the world's lightest and fastest service mesh, today announced the release of Linkerd 2.10. The newest version extends the maintainers' dedication to minimalism, composability, and building on top of the existing ecosystem, introducing new opt-in extensions that pare down Linkerd's default control plane install and allow for third-party augmentation. This release also extends Linkerd's seamless, secure multi-cluster support to all TCP connections, and adds opaque ports to make it easier to apply mTLS to all protocols. Linkerd 2.10 now weighs in at under 200mb at startup, down from ~500mb in Linkerd 2.9, shedding non-critical components that previously shipped by default. "Complexity is the enemy. Despite what other projects would have you believe, the service mesh doesn't have to be complex. We are fanatically dedicated to making Linkerd as small and simple as possible while delivering the features necessary to build secure, reliable applications on Kubernetes," said William Morgan, CEO of
