Card comments, Murmurs and history components
What you can do on this section of a card
The card Comments or 'Comments/Murmurs' component shows any comments (and/or Murmurs) made by project team members.
If you wish to just view comments on a card, and not the Murmurs associated with the card as well, you can filter out the Murmurs by unchecking the 'Show Murmurs' checkbox on each card's Comments/Murmurs component.
The card History component shows a summary of all changes made to the selected card, including who made the change and how long ago the change was made. Click the View link next to a version number to display this card version. When you're viewing an older card version, Mingle shows the version number and how long ago the version was updated. From here you can click to return to the latest version.
If your team has integrated Mingle with your source repository, any changes to the source where this card's number was referenced in the commit messages will display here on the History component. You can setup Mingle to view any changes made to this card by any project team member by subscribing to feeds or email on Mingle's History tab.
