Release Notes

coder/code-server

### [`v4.8.0`](https://togithub.com/coder/code-server/blob/HEAD/CHANGELOG.md#​480-httpsgithubcomcodercode-serverreleasestagv480---2022-10-24) [Compare Source](https://togithub.com/coder/code-server/compare/v4.7.1...v4.8.0) Code v1.72.1 ##### Added - Support for the Ports panel which leverages code-server's built-in proxy. It also uses `VSCODE_PROXY_URI` where `{{port}}` is replace when forwarding a port. Example: `VSCODE_PROXY_URI=https://{{port}}.kyle.dev` would forward an application running on localhost:3000 to https://3000.kyle.dev - Support for `--disable-workspace-trust` CLI flag - Support for `--goto` flag to open file @​ line:column - Added Ubuntu-based images for Docker releases. If you run into issues with `PATH` being overwritten in Docker please try the Ubuntu image as this is a problem in the Debian base image. ##### Changed - Updated Code to 1.72.1 ##### Fixed - Enabled `BROWSER` environment variable - Patched `asExternalUri` to work so now extensions run inside code-server can use it
