New features and improvements:

• Added the new UltiMaker Factor 4+ printer, including profiles
• Added option to specify file association during the installation of Cura for windows, contributed by @hellAholic New Settings:
• Introduced Infill Start/End Preference settings that give control over the starting location of infill
• Added Support Infill option "Lightning", and in addition the following supporting settings: Support Lightning Angle, Support Lightning Overhang Angle, Support Lightning Prune Angle, and Support Lightning Straightening Angle, which together allow you to add and control lightning infill generated for support structures
• The Support Infill Line Multiplier has been introduced to increase the quantity of infill lines. When an even number of lines is specified through this setting and paired with lightning support, it produces a single extrusion line for each island
• Introduced Minimum Hole Area in Brim Support, which filters out small holes in the support brim, resulting in a more consistent brim
• Added Temperature Delta Top Surface, which allows you to print top surfaces at a different temperature
• Added more options to Retract Before Outer Wall to give more control over retraction behavior when traveling to the outer wall
• Added Initial Layer Wall Ordering which gives control over the order in which the walls are printed for the initial layer, contributed by @hellAholic Bug fixes:
• Support blockers now function correctly even when assigned to a disabled extruder; they no longer cause slicing conflicts and continue to effectively block support
• Fixed an issue where thin support structures would be generated within tree support
• Fixed an issue where the tree support interface layer would be missing
• Randomized infill now also works for infill skin support
• Fixed an issue where Keep or Discard profile user preference would be ignored
• Overhanging wall speed was previously applied too aggressively, resulting in extremely slow printing in overhanging areas
• Travel speed was applied to layer switches, resulting in high-speed Z-travels
• Fixed an issue where certain 3MF files would incorrectly load with an invalid setting configuration
• Fixed an issue where certain setting combinations would skip parts of the skin and walls sections
• Resolved an issue where slicing would fail when both Raft build plate adhesion and Support Lightning Infill were enabled
• Fixed an issue where overhang speed would be applied inconsistently when both Split Infill and Overhang Speed settings were enabled
• Fixed an issue where the profile has changes notification would overlap with UI elements
• Fixed an issue where certain setting configurations would cause a large amount of small line segments to be generated for the prime tower
• Fixed an issue where clicking the "Sign in to Digital Factory" button twice would fail to log in Printer definitions, profiles and materials:
• Updated high-speed S-Line profiles to improve tree support strength and improved seam behavior by ending infill close to the seam and traveling to the seam unretracted
• Improved material detection for Method line printers to automatically select support material for the raft interface
• Automatically disable Infill Skin Support if Gradual Infill Steps is enabled, since these are conflicting settings, contributed by @hellAholic
