At STAR, we publish several major and minor releases throughout the year. To provide greater visibility into the innovation and collaboration taking place across our member community, we are beginning a monthly release update series.
These updates are available to both members and non-members and highlight the progress STAR continues to make toward enabling standardized, interoperable automotive retail ecosystems.
