# Sometimes blender.org takes some time to release patch releases and because Arch users
# are impatient, we sometimes need to build from git directly.
# Update because I get so many queries on this:
# Due to our other rolling deps, it's sometimes not possible to build Blender stable releases.
# More often than not, a new openshadinglanguage breaks it and I could either backport fixes
# or simply roll with a new version. I usually choose the latter when the former seems
# unreasonable.
