We are happy to announce a new release of Kuma! Kuma 1.4.1 is a new n release that ships with 25+ new features and significant performance improvements at scale. We strongly suggest to upgrade, in order to take advantage of the latest and greatest when it comes to service mesh.

Notable Features:

• 🚀 Performance continues to be significantly improved. We’ve streamlined some JSON marshalling, which cuts memory consumption in half.
• 🚀 Authentication tokens are now simpler to manage.
• 🚀 Kubernetes Pods are automatically tagged to identify the Pod’s namespace, so you can easily build policies around the Pod.

And much more!

Also check the upgrade path.
