+## 📣 News and Upcoming Changes
+
+[Remote attach debugging](./debugging#connecting-to-headless-delve-with-target-specified-at-server-start-up) is now available via Delve's native DAP implementation with Delve v1.7.3 or newer.
+We plan to enable this as the default in 2022 H1 to enhance remote debugging with the same
+[debugging features](./debugging.md) that are already in use for local debugging.
+We recommend switching your remote attach configurations in `launch.json` to use
+`"debugAdapter":"dlv-dap"` now to verify that this works for you.
+Please [file a new issue](https://github.com/golang/vscode-go/issues/new/choose) if you encounter any problems.

+### Syntax highlighting does not seem to work.
+
+The default syntax highlighting for Go files is provided by a
+[TextMate rule](https://github.com/jeff-hykin/better-go-syntax) embedded in VS Code,
+not by this extension.
+
+For better syntax highlighting (including generics support), we recommend enabling
+[semantic highlighting](https://code.visualstudio.com/api/language-extensions/semantic-highlight-guide)
+by turning on [Gopls' `ui.semanticTokens` setting](https://github.com/golang/vscode-go/blob/master/docs/settings.md#uisemantictokens).
+
+```json
+"gopls": { "ui.semanticTokens": true }
+```
