This minor release is just a technical refactor.
The primitives for drawing sketchy lines and curves (as used by the "framebox" package in the collection) have been extracted to the rough module, and this collection of package now depends on it.
This change should have no impact on users installing it via Luarocks (which takes care of installing the dependency automatically).
Other users (directly toying with a clone of the code, etc.) may need to run luarocks install rough.
