+### Major
+- **Chromium Core -> 151.0.7922.174**: Updated the BotBrowser 151 release line with upstream Web Platform, rendering, and security updates.
+
+### Improvements
+- **Per-Context Proxy and Geographic Consistency**: Improved runtime proxy updates, geographic identity delivery, and route reuse across browser contexts.
+- **Automatic GeoIP Resolution**: Improved resilient proxy-location resolution for supported address families and context lifecycle changes.
+- **WebKit-Family Runtime Consistency**: Improved profile-backed browser and worker runtime behavior while preserving Chromium-family sessions.
+- **SOCKS5 UDP Reliability**: Improved connection lifecycle stability for authorized UDP proxy and HTTP/3 workflows.

+- Automatic IP resolution can add context activation latency.
 - `--proxy-ip` removes that external IP resolution roundtrip.
