This makes the diff show only real API changes without preview artifacts like package name rewrites. ## 4.74.0 **`(feat):`** Resolve Windows symlinks via NTFS junctions during bundle extraction instead of running pnpm install in standalone. This enables docs preview on Windows without elevated privileges. ## 4.73.0 **`(feat):`** Present an interactive TUI dropdown when the user omits `--api`, `--instance`, or `--group` flags and multiple options exist. In TTY environments the CLI now prompts for selection instead of failing hard. Non-TTY environments retain the previous error behavior. ## 4.72.0 **`(feat):`** Polish `fern config migrate` command: point the `docs` key at the existing `docs.yml` file via `$ref` syntax instead of inlining, drop legacy `defaultGroup` and `group` fields from SDK target output, and automatically update GitHub Actions workflow files to use the v2 CLI syntax (`fern sdk generate`, `--target` instead of `--group`). ## 4.71.6 **`(fix):`** Fix MDX rendering of C++ library docs by properly escaping angle brackets in template parameters and HTML-like tags within description text. Unescaped angle brackets (e.g. `vector`, ``) caused MDX parse failures.
