Canvases are surfaces built into Slack where members can create and share fully-formatted content. Channel and direct message (DM) canvases are available on all plans, while standalone canvases are only available on paid plans. Owners and admins can manage access to canvas version history, and turn off canvas update messages for channel and DM canvases.
Manage canvas version history
Anyone with permission to edit a canvas can access its revision history and restore a previous version. If you’d like, you can disable canvas version history so that only the most recent version is available.
