create_report takes a layout — grid or canvas — so an assistant can create a free-canvas report rather than always landing on the grid. It also takes cover and thank-you overrides, and update_report takes the overrides (not the layout, which is fixed at creation).

Widgets added to a free-canvas report are now sized correctly. The server used to place every widget in grid units; on a canvas page those numbers are read as pixels, so an assistant-added widget arrived a few pixels wide. It is now converted to the page's own pixels.
