# 20250125 bkw: update for v0.13.0.
# 20241109 bkw: update for v0.12.1, which is a fork by a different
# upstream. the original project's README says "project has been
# unmaintained since 2016 and should not be used". using a self-hosted
# copy of the release tarball to avoid content-disposition shenanigans.

# 20240905 bkw:
# - new maintainer.
