A deprecated experiment. See Project Fluent instead.
L20n.js has been deprecated and is no longer maintained. Please use Fluent, the successor to L20n developed by the same team at Mozilla. Fluent is a mature localization system currently used in Firefox and in many other Mozilla projects.
Code-wise, l20n.js 6.0.0 is the same as 5.0.0. We're publishing it as a major version to reduce disruptions which may result from the deprecation. Only version 6.0.0 has been deprecated on npm. Existing projects using earlier versions won't receive deprecation warnings when running npm install.
