There is a new pull request by thypon against master on the void-packages repository

https://github.com/thypon/void-packages mkinitcpio-zstd
https://github.com/void-linux/void-packages/pull/29062

mkinitcpio: update to 30.
The only meaningful change is switch to zstd as default initrd image.
I'm tempted to not merge this one since I'm not sure all our kernels support zstd atm.

A patch file from https://github.com/void-linux/void-packages/pull/29062.patch is attached
