At the bottom left corner of the Booking Window you'll find the Booking History which tracks who, when and for which project a Booking was created and also all the changes applied to the Booking afterwards.
Starting from version 7.2, the Booking History now includes changes made to Booking Custom Fields, displaying both the previous and updated values for the following field types:
- Entry CF
- Date CF
- Selector CF
- Note CF
- File CF
- Checkbox CF
For fields containing lengthy values, the full content can be viewed by hovering over the specific history entry, which will display the details in a yellow tooltip.
