drush rn formats output in HTML instead of markdown --md not recognized

[jenlampton]

I've switched from using the 1.x-0.x branch of drush to 1.x-1.x but now my drush rn command has reverted back to the drupal style output. The list provided is in HTML instead of markup, and the links are to /node/XXX instead of github issues. I also tried using --md but got

Unknown option: --md.  See `drush help release-notes` for available options. To suppress this error, add the option --strict=0.

Here's my setup, lmk if you see anything wrong:

Update: I switched back to the 0.x branch and now drush rn is not working for me either. I don't think I was previously running a patched version, so my guess is that I've broken something. Advice appreciated.

I checked the codebase and see code in grn/grn.drush.inc for release-notes but when I run drush rn help I get the following error:
