hi everyone,

I got a bug report (https://github.com/fangq/mmc/issues/113) related to pmmc.

It turns out that the recently released v2025.10 version of mmc raises an error when running simulations while saving detected photon data (which is quite common). I just applied an emergency fix and rebuilt all mmc/mmclab packages. Because mcxstudio packages/installer also contain mmc/mmclab, they are also rebuilt and reuploaded.

You should be able to find these updated packages under:

https://sourceforge.net/projects/mcx/files/mmc/
https://sourceforge.net/projects/mcx/files/MCXStudio/v2025.10/

if you use mmc/mmclab, I urge you to redownload the updated v2025.10 package files and overwrite what you previously used. pmmc version was also bumped to 0.3.6 to include this fix. You should be able to update it using `python3 -m pip install --upgrade pmmc`
