Note for previous users

Note for users who have been using L0Learn before July 2018: The new CRAN version introduces many new major features, which unfortunately required doing some changes to the API. The old non-CRAN version (i.e., the one installed directly using devtools from Github) is now archived and its API will not be maintained anymore. As a courtesy, you can still access the old version and its documentation at this link. The API of the CRAN version is now stable, and we will ensure backward compatibility in the future versions of L0Learn.
