I released Parenscript 2.1 (starting with this release Parenscript releases are identified by version numbers instead of dates) this week. Check out the updated reference manual.
Eager Future also got a new release, adding a requested feature: optional eagerness.
Paddy Mullen has taken over css-lite development. His fork includes new features and more code examples. You can find it on github: https://github.com/paddymul/css-lite
Thomas de Grivel forked uri-template: cl-uri-templates adds the substitution operators introduced in the third draft of the URI Template proposal. I think the substitution operators are quite horrible and have abstained from implementing them.
