What changed

This notice from the DOJ Antitrust Division announces updates to the membership of the Rust Foundation, a venture operating under the National Cooperative Research and Production Act of 1993. Specifically, Doulos, Meilisearch, and Trafficking Free Tomorrow have been added as parties, while Lynx Software Technologies has withdrawn. These changes do not alter the planned activities of the group research project.

This filing is a routine update to maintain the protections afforded by the Act, which limits antitrust plaintiff recovery to actual damages under specified circumstances. Compliance officers should note that membership remains open, and further notifications are expected. No immediate action is required for entities not directly involved in this specific cooperative research project, but it highlights ongoing activity within the open-source software development community that may have antitrust implications.
