What is Linkerd?
Linkerd pairs post-quantum mTLS with steady mesh perf work, on a blog-as-changelog feed.
Linkerd, the CNCF-graduated Rust service mesh, tracks its project blog rather than a pure release feed — so genuine version announcements (2.19, 2.20) sit alongside community deep-dives and republished educational essays. The product itself is in a mature, security-forward phase: 2.19 shipped post-quantum mTLS by default, and 2.20 follows with rate-limit-aware load balancing, lower memory use, and better inbound metrics. Native sidecars graduated to beta over this stretch.
What is Rivet?
Rivet is rebuilding its actor backend into managed infrastructure for AI agents.
Rivet ships an actor-model backend - durable per-actor state, SQLite, queues - and is now stacking AI-agent infrastructure on top of it: agentOS (WASM micro-VMs for running coding agents), Secure Exec (isolated process execution), and SDKs in Rust and Effect. The pace is unusual: five 'Introducing' releases in ten days. The core is being rewritten in Rust as it goes.

Linkerd
2.5DEVOPS
Linkerd pairs post-quantum mTLS with steady mesh perf work, on a blog-as-changelog feed.
◆ Current state
Linkerd, the CNCF-graduated Rust service mesh, tracks its project blog rather than a pure release feed — so genuine version announcements (2.19, 2.20) sit alongside community deep-dives and republished educational essays. The product itself is in a mature, security-forward phase: 2.19 shipped post-quantum mTLS by default, and 2.20 follows with rate-limit-aware load balancing, lower memory use, and better inbound metrics. Native sidecars graduated to beta over this stretch.
◆ Where it's heading
Two arcs run in parallel. The product is doubling down on operational simplicity and secure defaults — post-quantum crypto, native-sidecar maturation, OpenTelemetry consolidation (dropping the jaeger extension and OpenCensus), and steady proxy memory and metrics work across edge releases. The blog is simultaneously being used to seed community education (protocol detection, destination internals, certificate rotation), pointing to an adoption-and-retention push alongside the engineering cadence.
◆ Prediction
Expect the weekly edge-release train to keep feeding the next stable after 2.20, with more memory/metrics hardening and native-sidecar and Gateway API work. The crawled feed will keep interleaving real announcements with educational posts, so signal will stay mixed.
Rivet
6.3DEVOPS
Rivet is rebuilding its actor backend into managed infrastructure for AI agents.
◆ Current state
Rivet ships an actor-model backend - durable per-actor state, SQLite, queues - and is now stacking AI-agent infrastructure on top of it: agentOS (WASM micro-VMs for running coding agents), Secure Exec (isolated process execution), and SDKs in Rust and Effect. The pace is unusual: five 'Introducing' releases in ten days. The core is being rewritten in Rust as it goes.
◆ Where it's heading
The center of gravity is moving from a framework for stateful actors toward a managed platform for hosting agents and their compute. Rivet Compute adds one-command serverless hosting; agentOS and Secure Exec target the sandbox-for-coding-agents market directly. Each release widens the surface a developer can run without managing infrastructure.
◆ Prediction
Expect Rivet to keep filling out the managed-hosting story around Compute - pricing, regions, and tighter agentOS/Secure Exec integration so the actor model and the agent sandbox share one deploy path.
