+### Change default port from 5000 to 8000 - @DaleSeo PR #417
+
+The default server port has been changed from `5000` to `8000` to avoid conflicts with common development tools and services that typically use port 5000 (such as macOS AirPlay, Flask development servers, and other local services).
+
+**Migration**: If you were relying on the default port 5000, you can continue using it by explicitly setting the port in your configuration file or command line arguments.
+
+- Before 
+
+```yaml
+transport:
+  type: streamable_http
+```
+
+- After
+
+```yaml
+transport:
+  type: streamable_http
+  port: 5000
+```
