This release includes several major changes to the proxy's behavior: - Service profile lookups are now necessary and fundamental to outbound discovery for HTTP traffic. That is, if a service profile lookup is rejected, endpoint discovery will not be performed; and endpoint discovery must succeed for all destinations that are permitted by service profiles. This simplifies caching and buffering to reduce latency (especially under concurrency). - Service discovery is now performed for all TCP traffic, and connections are balanced over endpoints according to connection latency. - This enables mTLS for **all** meshed connections; not just HTTP. - Outbound TCP metrics are now hydrated with endpoint-specific labels. --- * outbound: Cache balancers within profile stack (linkerd/linkerd2-proxy#641) * outbound: Remove unused error type (linkerd/linkerd2-proxy#648) * Eliminate the ConnectAddr trait (linkerd/linkerd2-proxy#649) * profiles: Do not rely on tuples as stack targets (linkerd/linkerd2-proxy#650) * proxy-http: Remove unneeded boilerplate (linkerd/linkerd2-proxy#651) * outbound: Clarify Http target types (linkerd/linkerd2-proxy#653) * outbound: TCP discovery and load balancing (linkerd/linkerd2-proxy#652) * metrics: Add endpoint labels to outbound TCP metrics (linkerd/linkerd2-proxy#654)
