Last beta branch before 2.7 and then 2.8

#known issues

• the title bar still show "2.5.59", it will be fixed in next version. The good version is in help->about.
• It can crash when it's trying to create seam positions. fixed in nightly.

new

• Split perimeters (perimeter count) into contour & hole (only for classic process)
  
• New setting: solid_infill_below_layer_area & solid_infill_below_width (force solid infill if area of region/layer below a threshold)
• Split solid_overlap into top_solid_infill_overlap
• Add Graph Widget (still wip)
  • New setting: extruder_extrusion_multiplier_speed (change extrusion multiplier in relation to the current extrusion speed)
  • Implement Small Area Solid Infill Flow Compensation (from orca) #4329
    • Original implementation by @Alexander-T-Moss, port by @mjonuschat, reworked to use the graph widget.
      
• Add overhangs_max_slope
  • allow to modify the slices to reduce the overhangs slope (but bridges) with overhangs_bridge_threshold
  • limit the length of bridges (if set to 0, ignore bridges) and overhangs_bridge_upper_layers
  • allow to take into account future bridges on upper level, avoiding overhangs in area where a bridge will appear (useful for screw holes in bottom).
    
    
• better bridge:
  • new setting: bridge_precision (change the number of lines used to detect bridges)
  • better direction detection
  • better coverage
  • better shape
• Update to acceleration: move to object/region & cleaning alongside it. (rename bridge_internal_* settings to internal_bridge, like orca)
• Pressure advance calibration tool (v1) by legend069
• Allow to load monotonicgapfill for solid_fill_pattern #3281
• Add estimated date of printing end. #4275
• New setting: priming_position #4332
• Post-process ironing angle: now use fill_angle_cross, and can go into negative. #4286
• New setting: fill_angle_follow_model: Allow the infill to rotate alongside the object's z rotation. #4304
• Add fill_angle to quick infill modifier (right-click -> infill) #4304
• Change gapfill type from 'gapfill' to 'support interface' for support interfaces (tell me if this creates some issues).
• Split interface pattern into top pattern and bottom pattern
• Add chamber temperature gcode if not detected. (M191 and M141, only for marlin2, reprap and machinekit) #4289
• New hidden print settings for calibration (accessible via modifiers)
  • print_first_layer_temperature to be able to set the first layer temperature from a print setting#4245
  • object_gcode: to add custom gcode each time an object's perimeter and infill start to print (at least one per layer)
  • region_gcode: to add custom gcode each time a region's (modifier) perimeter and infill start to print (at least one per layer)
• Better status message: for prepare infill, sequential object gcode, seam visibility
• Performance improvements
• Multithreading improvement
• Improved path sorting

changes-fixes

• always run the fan_speed post-processing to remove duplicate M106 #4225
• Also use offset for only_retract_when_crossing_perimeters, so it retract if the line goes over the external perimeter #4294

known issues

• some problems with windows 11 #3985 #4071
• some open issues are reported for 2.7 build #4045 #4037 #4036 #3996 #3923
• If you have problem with macos, check that post

notes

I haven't tested the linux & macos build.
The mac intel version will ask you for permission, and the arm will tell you it's corrupted. You need to do xattr -cr /Applications/SuperSlicer.app.
For Windows automatic installer/updates: https://community.chocolatey.org/packages/superslicer . Note that it has some days of delay, for the validation process. (I'll try to add superslicer also into winget)
You can have daily builds in the action menu of github.
