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 subscriptions, while standalone canvases are only available on paid subscriptions. 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.

Manage canvas update messages
When someone in your workspace or organisation updates a channel or DM canvas, we’ll send a message to the conversation to help keep other members informed of the changes. You can turn these update messages off, or allow members to manage canvas update messages in individual conversations.
