XProc 3.0: Ready or Not
summary
Core language goes to Last Call (February 2020) while the standard step library remains pending; the group removes the serialize-map function and tightens URI semantics. Two implementations exist and aim for public betas around March, with interoperability work to be API-compatible. Test suite totals ~1,700 tests and one implementation reports about 74.82% pass rate. XProc 3.0 adds cast-content-type for non‑XML payloads, maps for parameter passing, multiple catches in try/catch, archive and HTTP steps, and simplified output serialization.
