+## 0.34.3 — QUIC socket buffering, live HTTP/3 settings and cache outcome mix (source candidate)
+
+- QUIC now opens the UDP listener socket with per-listener receive/send buffer targets (4 MiB each by default; `udp_receive_buffer_bytes`, `udp_send_buffer_bytes`; `0` uses OS defaults). Reports the effective buffer sizes and warns if kernel limits clamp them. Linux `SO_RCVBUF` / `SO_SNDBUF` accounting is accommodated, so observed `ss` values correspond to the configured effective target when permitted. UDP buffer modifications require restart, not silent hot application. Existing configs without these fields load the new defaults.
+- HTTP/3 `Alt-Svc` follows newly saved listener lifetime immediately on H1/H2 TLS responses for an already-bound H3 socket; disabling H3 publishes `Alt-Svc: clear`. New QUIC handshakes use saved stream/idle limits and reduced connection caps. Listener binding/TLS/H1-H2 changes, a new/disabled UDP listener or expanding startup capacity still need restart; UI restart indicator reflects this.
+- DEBUG-level bulk QUIC snapshots expose packet loss, congestion window, RTT, MTU and datagram syscall counters to investigate slow H3 and CPU usage, without assuming an unmeasured throughput improvement.
+- Overview adds a **recent HTTP cache outcomes** 100% stacked bar with HIT, MISS, BYPASS and OTHER (requests with no cache decision); retains the original lifetime HIT/MISS donut. Samples exclude pauses/resets and do not normalize invalid counter differences into misleading percentages. The widget is included in the dashboard registry and factory preset but **hidden by default**; administrators can enable it in the layout editor. Saved layout visibility is preserved. Both UI languages are supported.
+- Delivered as source for compilation and protocol acceptance on supported targets; no compiled Rust binary or measured post-patch benchmark is included in this candidate.
