+## 0.34.0
+
+- Optimize reverse-proxy hot path with shared immutable compiled route handles,
+  reusing the observer's host/location selection in forwarding without changing
+  ACL, rate, canonical authority or protocol enforcement.
+- Avoid wildcard allocations for exact-host hits; preserve host precedence,
+  listener bindings, regex and internal named-location fallback behavior.
+- Add allocation-free, scheduler-lock-free single-backend LB selection for
+  non-cookie pools. Keep health/drain/capacity admission, retry and lease
+  lifetime; preserve multi-backend algorithms and cookie-affinity semantics.
+- Make healthy-backend selection lock-free using a synchronized atomic status
+  tag; share compiled health/passive policies between leases rather than
+  deep-cloning their strings per request. Preserve recovery state machine.
+- Prepare error-fallback and retry request headers only when the operation is
+  configured/eligible. Keep error-response interception and safe-method replay.
+- Replace exchange source, cache and transform telemetry mutexes with atomic
+  tags without changing log/event field names or tri-state flags. Do not clone
+  live-stream log entries when there are no subscribers and move terminal
+  exchange fields into the final log record; history and sinks stay.
+- Add routing/health/LB/telemetry regression cases and source-only guardrails.
+  No new configuration fields, migrations, LB switches, or changed keepalive
+  defaults. Actual Rust compilation and benchmark are required before rollout.
+
+- Separate global cache representation compatibility from per-vhost scopes.
+  Keep HOT and COLD entries across vhost keepalive/recycle/LB diagnostics saves;
+  invalidate only modified content-bearing scopes and cancel their in-flight fills.
+- Persist a content fingerprint alongside COLD entries so interrupted scoped
+  purges cannot resurrect old responses after restart; retain COLD format v3.
+- Remove per-frame `Exchange.backend` mutex acquisition from response body
+  metering by retaining the final backend lease with the body; request metering,
+  lease lifetime, counters and error handling retain their semantics.
+- Guard cache-ticket creation against in-flight requests using an obsolete
+  configuration snapshot after a successful save, without evicting unchanged
+  cache entries.
+- Add regression tests for operational saves, scoped content changes and COLD
+  restart compatibility. No LB UI changes or new database migration.
+- Add `sendfile: off | auto` to Web Service configuration and Delivery editor.
+  For eligible Linux cleartext HTTP/1.1 GET >=64 KiB, transfer already-authorized
+  static file descriptors using native `sendfile(2)` behind a bounded connection
+  bridge. Keep normal streaming for TLS/H2/H3, range, transforms, compressed
+  bodies, active object cache and other operating systems. Disabled by default.
+- Keep the kernel transport switch outside global cache identity; toggling it
+  must not invalidate HOT or COLD. Include native transport/fallback regression
+  test cases and panel save/reload tests (Rust tests still need execution).
+- Include an explicitly hypothetical Amdahl model of nginx parity using the
+  existing 0.33.8 benchmark, with no claim of measured 0.34.0 RPS improvement.
+- Actual Rust compilation, protocol/regression execution and comparative RPS
+  benchmarking are required before deployment; do not infer throughput gains
+  from the source-level changes alone.
+
 ## 0.33.8
 
 - Skip cache-only policy maps, request snapshots and ticket work when caching
