Fluxheim 1.6.1 Release Notes

Fluxheim 1.6.1 starts the first Pingora-exit implementation release after the
1.6.0 foundation tag. The first concrete fix is release infrastructure: focused
load-balancer container images are again part of normal tag builds for the
1.6.x line.

Changed

• Fixed the container image workflow so the load-balancer image profile builds
  on normal tag pushes after v1.5.x, including v1.6.x.
• Kept the manual include_load_balancer=true override only for older or
  non-release manual dispatch refs.
• Removed pingora-load-balancing and pingora-ketama from full and
  load-balancer image profile dependency trees by moving backend-set storage to
  Fluxheim-native backend types.
• Replaced the Pingora TCP health-check adapter with a Fluxheim-owned TCP
  connector and rustls/OpenSSL TLS handshake paths.
• Added scripts/smoke_load_balancer_container.sh so release testing can build
  the focused load-balancer image and prove round-robin plus header persistence
  behavior through a real container, while also checking that
  pingora-load-balancing and pingora-ketama are absent from that profile's
  dependency tree.
• Split load-balancer API/runtime DTOs and parser helpers into a focused
  api.rs module. Existing public re-exports remain stable; the change is a
  reviewability step for the 1.6 modularity policy, not a config or runtime
  behavior change.
• Moved the Pingora ServiceWithDependents adapter for load-balancer
  discovery/health background work into the root runtime crate. The
  load-balancer crate now owns its shutdown/ready primitives and no longer
  imports Pingora service/listener/shutdown types.
• Moved load-balancer request-key extraction behind a Fluxheim-owned
  LoadBalancerRequestView trait. Pingora request headers are now adapted at
  the root proxy boundary, while selection and persistence code stays
  transport-neutral.
• Bounded native TLS TCP health-check handshakes with the configured connect
  timeout. This prevents a backend that accepts TCP but stalls during TLS from
  blocking the load-balancer health/discovery loop.
• Updated workspace, RPM, README, build documentation, and release notes to
  1.6.1.

Notes

• This release completes the active dependency cut from pingora-load-balancing.
  The pingora HTTP health-check connector remains the only Pingora import
  inside fluxheim-load-balancer production code and is scheduled for a later
  HTTP/runtime cutover release in the 1.6 line.
