About all I can manage at the moment as far as open-source “contributions” go (packaging up someone else’s hard work).
Libvips switched to the meson build system with 8.14. I can’t say I’m a huge fan, I prefer the simplicity of autotools, but fortunately switching over was much easier than I thought (even doing all the changes via my phone) thanks to a bunch of other hard work by others.
It irks me that my markup is wrong in the commit message and I can’t ever change it.
