   - Components that are not referenced in any connection set will not be rendered. Instead, a warning will be output in the console. ([#328](https://github.com/wireviz/WireViz/issues/328), [#332](https://github.com/wireviz/WireViz/pull/332))
 - New command line interface ([#244](https://github.com/wireviz/WireViz/pull/244)). Run `wireviz --help` for details 
   - The path specified with the `-o`/`--output-dir` option no longer includes the filename (without extension) of the generated files. Use the `-O`/`--output-name` option to specify a different filename for the generated files.
+- The `.gv` file is no longer included as a default output format (only as an intermediate file during processing) unless specified with the new `-f` option described below.
