+
+We've just released **Dev Proxy v2.3.2** - a patch release that fixes Chrome DevTools inspection broken on Chromium 146+.
+
+### **In this version:**
+
+- Fixed **DevToolsPlugin** WebSocket connection failing on Chromium 146+ (Chrome and Edge)
+
+### **Fixed Chrome DevTools inspection**
+
+If you use the **DevToolsPlugin** to inspect intercepted requests in Chrome DevTools, you may have noticed that the WebSocket connection stopped working after updating Chrome or Edge to version 146 or later. DevTools would open but fail to connect, leaving you unable to inspect requests:

+
+The issue? Starting with Chromium 146, the browser resolves `localhost` differently for WebSocket connections. Dev Proxy's internal WebSocket server was binding to `localhost`, which no longer worked reliably with the updated Chromium network stack.
+
+**What changed:**
+
+We updated the WebSocket server and the DevTools inspector URL to use the IPv4 loopback address (`127.0.0.1`) instead of `localhost`. This small but important change restores full compatibility with Chromium 146+ while continuing to work with older browser versions.
