Envoy Version History
4 active, 34 end-of-life. 38 versions tracked.
Envoy releases quarterly, following a predictable 3-month cadence. As the data plane behind Istio and many other service meshes, Envoy's release schedule directly impacts the service mesh ecosystem.
Recommendation
Use the latest stable Envoy release, or let your service mesh (Istio, Consul Connect) manage the Envoy version for you. Don't run Envoy versions independently unless you have a specific reason.

Envoy Support Policy
Envoy supports the latest release with regular patches. Older versions may receive critical security fixes at the maintainers' discretion. In practice, the Envoy community strongly recommends staying on the latest quarterly release.
What You Need to Know
Envoy's xDS v3 API is the current standard. xDS v2 has been removed. Make sure your control plane uses v3.
WASM (WebAssembly) ABI for Envoy extensions is stable, letting you write custom filters in Rust, C++, or Go.
Envoy's version is usually managed by your service mesh. Check Istio/Consul compatibility matrices for version alignment.
Envoy 1.28+ includes significant HTTP/3 improvements and better connection pooling.
