Prusa MINI+ (new firmware/PrusaSlicer 2.7.1) with input shaper superfast(!) …
I had same firmware on my MINI+ since I bought it 2 years ago.
But yesterday my younger son installed latest firmware.
Then I downloaded PrusaSlice 2.7.2 Linux appimage.
But that did not work on my latest 64bit Raspberry PiOS.
Reason is that PrusaSlicer requires OpenGL 3.2.
Next I downloaded 2.7.1 and that works like a charme.
It has the input shaper enhancements, together with new firmware giving huge acceleration increase.
I printed 3 layer 50x50mm part with 100% infill and "0.15mm speed".
Both videos below start at end of (slow) first layer.
But then MINI+ is superfast as I have not seen it before!

On weekend I constructed and 3Dprinted a dual Raspberry GS/HQ camera holder:

[for high framerate (>300fps) stereo video capturing, two concurrent 688x136@402fps recordings just work]
Although the tripod mount worked, I continued with original plan to create a PT stand for the holder:
By accident my OpenSCAD files made the print 10.2mm too wide, and I had to 3Dprint two round 5.1mm distance parts.
I just wanted to slice the corrected (10.2mm) less wide .stl with PrusaSlicer 2.6.0 to get time for new model, I used "0.15mm quality" before.
But starting that version tells me that it is incompatible with currently installed configuration bundles (from 2.7.1).
So for 2.6.0 the time to 3D print with "0.15mm quality" and 100% infill was 6h30m.
With 2.7.1 for same "0.15mm STRUCTURAL" and 100% infill the 2.7.1 PrusaSlicer generates 4h43m gcode.
And with "0.15mm speed" and 100% infill 4h27m gcode.
Obviously that design has not enough potential for high speed because there are nearly no long parts.
So I tried the camera holder (that took 1h16m with 2.6.0 and "0.15mm quality" and 100% infill) with 2.7.1.
"STRUCTURAL" .gcode print time 52m, "speed" 47m.
I would have awaited "speed" showing more difference for that model.
But overall ("STRUCTURAL" seems to be what was called "quality" in 2.6.0), STRUCTURAL is so much faster than quality in 2.6.0 without input shaper(!).
(I use 100% because I want the parts to be stiff and stable, and because they are one-time prints)

fwiw, I raised a bug regarding the PrusaSlicer OpenGL 3.2 requirement: https://github.com/prusa3d/PrusaSlicer/issues/12334
RE:
I love my new MINI+ (Input shaper, PrusaSlicer 2.7.1).
From "peek" screen recording of part of Octoprint control tab.
I turned the part in PrusaSlicer so that nozzle movement is parallel to long paths:

with 15% infill the fast speed becomes even better visible:
