Highlights

Digital factory integration.
Now you can open files directly from Digital Library projects. Then, after preparation, quickly and easily export them back. This feature is available for all users with an Ultimaker Essentials, Professional, or Excellence subscription. Learn more

"Line type" is now the default color scheme.
When entering the Preview mode, you don't have to switch manually to line type.

Z-seam is now clearly shown in preview mode.
This ensures that you will know whether the seam will be sufficiently hidden in the end product. This will also indicate the starting point of the print.
Thanks to @BasF0 for contributing to this feature

Other Features

New 'line width' color-scheme available in preview mode.
Line-width can now be selected as a color-scheme in preview mode.
Thanks to @Ghostkeeper for contributing to this feature

Weight estimation in decimals.
This provides a more detailed idea of the amount of material used - which is especially useful for smaller prints.

Split Shell category into Walls and Top/Bottom.
The shell category was a mix of settings about walls and settings about top/bottom, splitting them into two categories makes more sense.

Post-processing script to embed screenshot in gcode.
The ability to have thumbnails embedded.

Add checkbox for Extruder Offsets.
Ability to enable or disable the extruder offsets to gcode. This will be enabled by default unless it is in the printer's def.json file.
Contributed by @RFBomb.

Cura should work properly on MacOS 'Big Sur' now, afforded by upgrades to Python (to 3.8) and Qt (to 5.15).
If you had (UX, visual, graphics card) problems, specifically on (newer) MacOS versions, like Big Sur, you should be able to use this new version.
