edge-26.3.3Networking & Messaging

A routine dependency-heavy edge release: two proxy bumps (v2.343.0, v2.344.0), Go 1.25.8 upgrade, rustls update, and proxy-init 2.4.6 — no feature additions or breaking changes.

• securityrustls patch update — pull this into your proxy builds

  rustls went from 0.23.35 to 0.23.37 in the proxy. Two patch versions in one release suggests active bug or security fixes in the TLS layer. If you're running older edge releases, this is a good reason to roll forward. No CVE was cited, but TLS library patches should never be delayed in a service mesh context.

• enhancementTwo proxy versions landed — check the proxy changelog separately

  This release ships proxy v2.343.0 and v2.344.0 in sequence, meaning two rounds of proxy changes are bundled in. The release notes don't detail what changed in each proxy version. If you're tracking proxy behavior closely (routing, observability, protocol detection), check the linkerd2-proxy repo's changelog for these two versions before deploying.

• enhancementGo 1.25.8 in the control plane — standard maintenance upgrade

  The control plane is now on Go 1.25.8. This is a patch release of Go and likely includes minor runtime fixes. No action required unless you're building custom tooling against Linkerd's Go modules — in that case, align your toolchain accordingly.
