Today we’re happy to announce Linkerd 2.19! This release introduces a significant state-of-the-art security improvement for Linkerd: a modernized TLS stack that uses post-quantum key exchange algorithms by default.
Linkerd has now seen almost a decade of continuous improvement and evolution. Our goal is to build a service mesh that our users can rely on for 100 years. To do this, we partner with users like Grammarly to ensure that Linkerd can accelerate the full scale and scope of modern software environments—and then we feed those lessons directly back into the product. Linkerd 2.19 release is the third major version since the announcement of Buoyant’s profitability and Linkerd project sustainability a year ago, and continues our laser focus on operational simplicity—delivering the notoriously complex service mesh feature set in a way that is manageable, scalable, and performant.
