We’ve just added a way for you to define commits for your development version. It’s basically a way to define a commit message and it will be shown in the history of the deploys/reversions/commits in the Version Control panel. This is useful in particular if you want to save a time where the app was stable, to be able to easily revert to this time (by clicking on copy time).
Minor usability bug: When you click “Cancel” on the Commit message modal, the “Commit a development version” button is subsequently made not clickable until you refresh the editor.
