This release focuses on major tunnel architecture improvements for multi-relay safety and performance, alongside CLI reorganization and compute infrastructure enhancements.

Features

  • CLI reorganization: Regrouped egress under vpc and service under compute with improved table printing (a81bd67)
  • Slot-based overlay allocation: Implemented slot-based overlay allocation for multi-relay safety (f523635, 225d460, 41ee65d)
  • Live relay latency reporting: Report live relay latency from QUIC RTT and export path metrics (90315ec)
  • Load shedding: Added WithMaxRequestsInFlight load-shedding option to apiserver (af472a3)
  • HTTPS fetch support: Give globalOutbound tlsOptions so https:// fetch() works in workerd (73d473b)
  • Bundle tag resolution: Resolve bundle tags in the control plane (7212d31)

Bug Fixes

  • Tunnel stability: Stop aborted connects from bricking overlay prefixes (958e317)
  • Envoy supervisor: Stop the envoy supervisor from spinning after context cancellation (512cf36)
  • IPv6 overlay addresses: Skip DAD on overlay v6 addrs and drop addrs that fail to install (dddaf6f)
  • Registry credential security: Never send the registry credential to a redirect target (1147cb8)
  • Tenant catalog refresh: Refresh the whole tenant catalog under one resident queue key (86c22ab)
  • Service refresh: Refresh the resident demux on Service changes (60f8d13)

Improvements

  • Tunnel performance: Batch the kernel-TUN datapath and stop disabling offloads (a2c807d)
  • Relay allocation: Lease slots outside the allocator mutex with per-network singleflight (9108e91)
  • IPv4 pool management: Share IPv4 slice pool across a relay's publishers and allocate from relay-wide pool (4473558, a5d053a)
  • Relay probing: Probe all relays to completion when ranking (9ba684f)
  • Run status display: Order run status table by latency and restyle with brand palette (696da13, 63e27c3)
  • Tunnel run UX: Improve alpha tunnel run UX and don't bind health endpoint by default in interactive runs (fadaf7c, ef4df8e)
  • CLI text formatting: Drop em-dashes from user-facing help text (7ad2ca2)
  • Domain resolution: Resolve bare FQDNs in domain get/delete commands (1966ee0)
  • Logging: Log DNAT resyncs only when the destination set changes (58970f7)
  • Mux semantics: Make mux Add replace-semantics with owner-checked removal (12b1b1e)
  • Relay connection teardown: Make relay connection teardown identity-aware (4abfb71)
  • VNI allocation: Randomize relay VNI allocation base (c50a4c6)

Infrastructure

  • Workerd configuration: Use typed config and remove legacy host (20e0812)
  • Config schema: Replace config schema generator (14354b8)
  • Metadata generation: Opt into metadata.generation per resource (c0a7eab)
  • Field manager: Leave spec.source.oci.digest to the deploy field manager (efc2bf0)
  • Profiling cleanup: Remove automatic CPU profiling (b579411)
