Wim Leers created an issue. See original summary.

My best guess is that this is the problem:

drupal/core 8.0.0 requires symfony/console

… because grn is automatically turned into drupal/grn, it seems to automatically depend on drupal/core, even though it does not.

Because of the automagic stuff that d.o does (https://www.drupal.org/docs/develop/using-composer/using-composer-to-man...), I can't even figure out how to look at drupal/grn's composer.json. Which means I can't actually verify whether it's depending on drupal/core. composer itself also does not provide any helpful commands — at least not by looking at it its list of commands, or searching the web.

composer info --all drupal/grn should show the available version and composer metadata

Try composer global require --update-with-dependencies drupal/grn

Title: Impossible to install via composer » Impossible to install Git Release Notes for Drush (grn) via composer
Project: Git Release Notes for Drush » packages.drupal.org
Version: 8.x-2.x-dev » 7.x-1.x-dev

Not sure what the solution would be here, but it seems to be that all projects of type "drupal-drush" just just depend on "drupal/drush" and not "drupal/core"

Workaround: Add the git repo of grn to your composer.json. This will bypass the drupal.org integration and will read type:drupal-drush directly from the git repo.
