Region: automatic region detection now follows where your device actually is, not a country it once visited — the setting under Home › Manual › Region no longer sticks on an old value such as "Auto · China" after you leave China
Region: "Global" is now a real choice that stays put, distinct from Auto; picking Auto re-detects your region immediately
Smart Connect and servers: Smart Connect and the server list now follow the region you chose, including Iran, Russia and China
Routing: the app no longer keeps using a China-only connection route after you leave China
All platforms: stability and performance improvements on Android, iOS, macOS, Windows and Linux
