I left my job, so I can now concentrate to develop this software full time.
here it's a collection of pull request and bugfixes from the last version, before i merge with prusaslicer2.7

New

• Add 'external perimeter seam gap' (seam_gap_external) to be able to add a hole but only on the external perimeter, to print gears on bad printers. may work better than seam_notch, or maybe with both.
• Better concentric infill with gapfill
• Semi-parallel printing by @vova #3445
• Add a speed knob to the wipe tower. by @amforpeace #3569
• Add max layer height to adaptive layers by @vovodroid
• Width change on odd layers by @vovodroid #3688
• Add option to avoid z lift for short travels by Julian Schill #3695
• Show layer time by @vova
  • you can choose in preferences what to show in the slider.
• Rework of fan speed control by extrusion type. Thanks to @legend069 to have started this, with its pr. #3735 #3608 #3568 #3415 #3408 #3380 #3367 #3361 #3271 #3152 #2872 #2696 #2419 #2326
• pause_print_gcode and color_change_gcode use default value if empty based on g-code flavor. Started by @your-friend-alice #3943

Bugfixes

• fix perimeters/overhangs being cut
• fix crash when checking vase mode.
• double slider: fix crash, ticks on // prints. Layer 0 is the "before first layer" (from custom gcode). have to check if the pause isn't shifted.
• overhangs_speed_enforce: fix & add a simple mode for arachne
• fix current_position custom gcode variable by @dumitrugrl #3958
• Fix some arc G2/G3 generation bugs. #3707
• Better performance for archimedian chords (now can be used on big areas) #3827
• Fix crash with overhangs_reverse #3818
• Toolchange: Set the fan speed after the tag, not after any 'T' command #3874
• fix filament_max_volumetric_speed and max_volumetric_speed don't take into account first_layer_flow_ratio #3775
• others #3962 #3776 #3763

notes

I haven't tested the linux & macos build.
The mac arm isn't built anymore (until I find the will to reinstall & reconfigure the VM again).
The mac intel version will ask you for permission. You may 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.
You can have daily builds in the action menu of github.
You can support me with the "sponsor" button

The mac version sin't built, because I need to do some more work for it to be able to be built normally. You can take an intel-nightly to update an old version.
