Acquiring Ravel

Currently Ravel is being distributed via the Patreon page www.patreon.com/Ravelation. If you sign up to this page for US$7 per month, you will have access to the online store (and also posts containing new releases of Ravel ). Figure 86 shows the pre-release version of this process, using the Patreon page for Minsky, the Open-Source system dynamics program on which Ravel is built.

Once you have signed up to the Patreon page, you will have access to posts there that release new versions. Figure 87 shows one such post.

and install Ravel into your copy of Minsky . Once finished, the program will close and restart, and you will have the latest version of Ravel .

We expect to release a new version of Ravel at least once a month, and as often as once a week. This process will slow down when we release Ravel on its own commercial website towards the end of 2024.
