- Boxed HandshakeState in NoiseSession to reduce enum variant sizes
- Used is_ok() instead of let Ok(_) pattern
- Applied automatic clippy fixes for minor warnings
TUN Interface:
- Fixed adapter name to always be 'ostp_tun' by cleaning up stale
adapters before launch (prevents 'ostp_tun 2', 'ostp_tun 3', etc.)
- Parallelized route setup with tun2socks launch to save ~3 seconds
- Replaced fixed 2-second sleep with adapter readiness polling
- Added -NoProfile to all PowerShell calls for faster execution
Speed:
- Reduced handshake timeout from 10s to 5s
- Reduced tun2socks spawn buffer from 300ms to 0 (removed)
GUI:
- Added i18n support: English and Russian translations
- Language toggle button in header (EN/RU)
- Merged 'IP Ranges' field into 'Bypass IPs / CIDR Ranges'
- Removed separate IP ranges field
- All static text uses data-i18n attributes
- Status messages, labels, toasts all translated
- Replaced alert() calls with toast notifications
CI/CD:
- Added separate GUI build job for Windows x64 and arm64
- Produces ostp-windows-gui-{arch}.zip with: ostp-gui.exe + wintun.dll + tun2socks.exe
- Uses Tauri CLI v2 for build
Critical fixes (6):
- protocol.rs: in_flight_count() now counts only retransmittable Data frames,
not Ack/Nack control frames — eliminates false backpressure under load
- protocol.rs: NACK is now rate-limited to once per 30ms — prevents
retransmission storm during normal UDP jitter
- protocol.rs: zombie frames exceeding max_retries+4 are evicted each tick —
prevents unbounded memory growth and stale retransmits
- protocol.rs: Closing state now processes final in-flight packets instead
of silently dropping them — prevents data loss at session teardown
- server/lib.rs: stream_tx changed from bounded(10000) to unbounded_channel —
prevents TCP-reader collapse during Speedtest with 50+ streams
- bridge.rs: liveness timeout raised from 30s to 60s — prevents false
reconnect during heavy Speedtest load
Medium fixes (8):
- protocol.rs: ACK range truncation preserves cumulative range (index 0)
- bridge.rs: Ping now uses send_datagram() for correct TURN wrapping
- dispatcher.rs: replay_cache hard-capped at 100k entries (DoS protection)
- dispatcher.rs: old addr cleaned from addr_to_session on roaming
- server/lib.rs: TCP connect_target() now has 10s timeout
- config.rs: TURN section parsed during hot-reload
- proxy.rs: HTTP header parsing uses 512-byte chunks instead of 1-byte reads
- proxy.rs: stream_id wrap-around skips active IDs to prevent collision
- runner.rs: is_essential_log matches actual log strings from bridge.rs
Other:
- kex.rs: clearly marked as dead PQ stub (not used by protocol)
- README.md + README.ru.md: complete rewrite with architecture diagram
- docs/en/specification.md: updated ARQ section with all new semantics
