Steps
Open your board and click on the board name at the top
Click the hamburger menu (≡) at the top-left and select "Version history" from the menu
View all versions with timestamps showing when changes were made
Each version shows who made the changes and what was modified
Click on any previous version to preview it
Click "Restore" to revert to a previous version
Confirm the restoration action
The current version is replaced with the selected version
A new entry is created in version history for the restoration
Compare two versions by opening them side-by-side
Notes
All versions are automatically saved during collaboration
Version history retains at least 30 days of changes
Restoring creates a new version entry, not permanent deletion
Use meaningful descriptions when saving major updates
