  • Private communications directly with the ojAlgo developer(s). Unlimited number of questions, but 1 at the time. Asynchronous (e-mail based) communications only – no scheduled sessions of any kind.
  • Access to the private ojAlgo-extensions repository containing projects/modules for many artifacts extending ojAlgo.
  • Request new versions of ojAlgo extension artifacts – any existing artifact. New versions are typically not built (deployed to maven repository) unless requested.
