" summary

Announces Visual Studio integration moving to general availability and a new CLI in public preview, plus features: persistent URLs, multi-port tunnels, region-aware hosting, and tunnel inspection. Shows a GitHub webhook wired to a local server on port 4567 using devtunnel commands (login with devtunnel user login -g, devtunnel port create -p 4567, devtunnel access create -a, then devtunnel host), webhook deliveries arrive and trigger an SMS. Second demo exposes a web app on port 5080, uses the inspection UI to find a bug that increments capybara instead of cat and verifies the fix.
