Updates under development are published at R-Universe as soon as merged or commited into the main branch in the repositories at GitHub. Two packages that depend on a commercial closed-source driver, but usable with a free runtime of the driver, are published only at R-Universe. Some new, still unstable packages, are also only at R-Universe.
