Vecto 1.0.2 is out. It depends on the new 1.0.1 release of Salza-PNG to support writing the backing PNG out to a stream instead of to a file. My favorite new and exciting thing, though, is the addition of a clipping path.
There have been some little documentation & code fixes too. (This will be the last release announcement that makes it to Planet Lisp, until there's something really big and new and exciting to announce.)
