 - Introduced an Anycolor option for the UltiMaker S and F series enabling you to print with any UltiMaker color loaded in the material station that is compatible with the printjobs. Note that it’s only compatible with the latest version of the firmware (for Factor 4 >=10.1  and for S-series >=9.0)
 - Added an option to Export Package for Technical Support to the help menu, it includes a project file with the settings but also the logs
 - Improved the way materials are selected when using multiple extruders to print the build plate adhesion so it doesn't default to the first extruder but the best option instead.
