GitHub - ArduCAM/Arducam-Pivariety-V4L2-Driver: This driver is used for Arducam mipi camera with Pivariety board releases has no changelog, so we cannot know what’s is going on.
Even if Arducam prefers put binaries on the same release rather than do one release per release on github, you can also add a VERSION file or so with the changes made.
Thanks

I have submitted the update of this part to the colleague who updated the website, and he may not have uploaded it yet.
But this [0,32] range is a maximum value that libcamara hardcodes to adapt to all cameras.
For the specific range, you can refer to
cat /usr/share/libcamera/ipa/raspberrypi/arducam_64mp.json
You can see that there is a “map” at the end: [0.0, 0 ,15.0,1023], which can be understood as 0,15 corresponds to 0,1023
