+You can select the default debug adapter to use in all launch configurations and codelenses through the `"debugAdapter"` field in the [`"go.delveConfig"`](settings.md#go.delveConfig) setting. You can choose which debug adapter to use for individual launch configurations with the `"debugAdapter"` field in [your `launch.json` configuration](https://github.com/golang/vscode-go/blob/master/docs/debugging.md#snippets). Most settings will continue to work with in this new `"dlv-dap"` mode except [a few caveats](#features-and-caveats).
