KubeCon North America in Detroit wrapped a few weeks ago, and we’ve been pretty much full steam ahead since then with everything we took away from it! We were fortunate enough again to have a lot of great Linkerd content presented at the conference – if you missed the conference or weren’t able to see all these Linkerd talks, we have everything you need to get caught up below.

Earlier this week, OpenSSL released a security advisory detailing two high-severity vulnerabilities in certain versions of OpenSSL. After careful investigation, the Buoyant security team has determined that the latest Linkerd releases (2.12, 2.12.1, and 2.12.2) are not vulnerable to the noted exploits, and that no action is required by users of the latest Linkerd releases to mitigate these vulnerabilities in Linkerd.

As the company that coined the service mesh term, we are always keenly interested in understanding where engineers are at in their service mesh adoption. That's why, after surveying KubeCon L.A. attendees last October, we decided to do the same in Valencia. And just as in L.A., we gained some fascinating insights. Here's a snapshot.

Believe it or not, it’s time for KubeCon + CloudNativeCon NA 2022 – and, once again, you’ll find a lot of great Linkerd content there! We’ve put together this Linkerd Community Guide to help make sure you don't miss any of these delightful nuggets of Linkerd goodness.

Are you a KubeCon geek who can't wait for Detroit to happen? No need to wait. Join us at KubeCrash, the KubeCon Detroit warm-up, for crash courses on cloud native tech by the maintainers of CNCF and other open source projects.

Today we’re very happy to announce the release of Linkerd 2.12. This massive release introduces route-based policy to Linkerd, allowing users to define and enforce authorization policies based on HTTP routes in a fully zero-trust way. These policies are built on Linkerd's strong workload identities, secured by mutual TLS, and configured using types from Kubernetes' s new Gateway API.

In the upcoming 2.12 release, Linkerd will take a first step towards adopting the Gateway API as core configuration framework. While this API was originally designed to handle ingress traffic, we believe it has a lot of potential for service meshes as well. In this blog post we'll cover some of our thinking behind this choice and what, if anything, it means for you.

This year’s KubeCon in sunny Valencia was once again full of amazing Linkerd news! The CNCF’s service mesh micro-survey showed Linkerd usage skyrocketing, with 73% using or planning to use Linkerd in the next year. The world’s lightest, fastest, most secure service mesh is now fully managed. And …
