The Citation Style Language (CSL) team is happy to announce CSL 1.0.1. CSL 1.0.1 is an (almost completely) backwards compatible release, and CSL 1.0 styles and locale files don’t have to be updated to work with CSL 1.0.1-compatible software. CSL 1.0.1 is a relatively minor update, but adds a variety of new features to CSL, and an extra layer of polish to both the specification and schema.
