I am currently using Drupal core 7.7 and Commerce 7.x-1.0-rc3 which requires changes that are only currently present in Drupal core 7.x-dev.
If I upgrade to 7.x-dev now in order to get the updates that the latest Commerce version needs, am I committing my project to following dev branch, and is there a danger of not being able to come back to stable cleanly, when the next stable release comes about?
It's not a live site, so temporary instability a dev branch may introduce is not necessarily an issue if I'll end up back on stable soon.
EDIT: Additionally, instruction for how to upgrade core from stable to dev using Drush would be super: Drush: Update core from stable to dev :)
