Upgrade to 0.15.0

[CGenie]

Hello,
Could this package be upgraded to 0.15.0? :)

do you want some help in doing the work?

[justinwoo]

i think this will be fairly trivial for you to do, seeing that you have already updated some other packages

Similar to milkis, I made only code changes, no new package manager.
