+Your proxy traffic looks identical to normal HTTPS traffic. The **Fake TLS V2** engine mirrors real TLS 1.3 sessions — per-domain profiles, real cipher suites, dynamic certificate lengths, and realistic record fragmentation. The TLS handshake SNI points to a cover domain (e.g., `cloudflare.com`), making it indistinguishable from regular web browsing to any DPI system.
 
 **Traffic masking** goes further — when a non-Telegram client probes your server, the connection is forwarded to the real cover domain. Your server responds exactly like cloudflare.com would.

+## 📋 Changelog
+
+### v1.2.0 — Engine v3.0.7 + Custom IP
+
+**Engine Upgrade (v3.0.4 → v3.0.7):**
+
+- **Fake TLS V2** — Complete rewrite of the TLS front. Handshakes now mirror real TLS 1.3 sessions with per-domain profiles, dynamic certificate lengths, and realistic record fragmentation. Significantly harder to fingerprint via DPI
+- **ME Pool V2** — Middle-end connections now use keepalive padding frames, staggered warmup, and exponential backoff reconnects for better stability under load
+- **Dynamic config reload** — Engine picks up config.toml changes without a restart
+- **SOCKS proxy hostname support** — Upstream SOCKS4/SOCKS5 proxies now accept hostnames in addition to IPs
+- **Frame size fixes** — Resolved "frame too large" errors on middle-end connections
+- **Extended handshake timeout** — `client_handshake` raised from 15s to 30s for slow networks
+
+**New Features:**
+
+- **Custom IP** — Set a custom IP for proxy links when behind NAT, CDN, or multi-IP setups. The proxy still binds to all interfaces — this only affects link/QR generation
+  ```bash
+  mtproxymax ip 203.0.113.50    # Set custom IP
+  mtproxymax ip auto             # Reset to auto-detect
+  ```
+  Also available in the setup wizard and TUI settings menu
+
+**Performance:**
+
+- **LTO builds** — Engine compiled with Link-Time Optimization (`LTO=true`, `codegen-units=1`) for ~10-20% faster throughput
+- **No default resource caps** — Docker CPU/memory limits now default to unlimited instead of 1 core / 256MB
+
+### v1.1.0 — Per-User Limits + Telegram Bot
+
+- Per-user connection, IP, quota, and expiry limits
+- Telegram bot with 17 commands for remote management
+- Proxy chaining via SOCKS5/SOCKS4 upstreams
+- Geo-blocking with CIDR blocklists
+- Auto-recovery with Telegram alerts
+
+### v1.0.0 — Initial Release
+
+- Full MTProto proxy management with telemt 3.x Rust engine
+- Interactive TUI + complete CLI
+- Multi-user secret management with QR codes
+- FakeTLS obfuscation with traffic masking
+- Prometheus metrics endpoint
+- Auto-update system
