FusionAuth's version 1.19, released in early September, introduces several notable features and improvements while maintaining backward compatibility. Key highlights include revamped configuration options allowing settings through environment variables, Java system properties, or a properties file, with flexibility for Docker or Kubernetes users. New login page hinting allows users to bypass the FusionAuth login page and connect directly to third-party identity providers, enhancing the user experience. The release also supports importing refresh tokens from other systems to ensure seamless migrations, and introduces application-specific email templates for private label applications. With this update, session pinning is no longer required for the administrative interface and login pages, facilitating a stateless application architecture. Additionally, FusionAuth now supports true multi-tenant single-sign-on (SSO), enabling users to sign in to multiple applications across different tenants using the same browser. The release also includes various bug fixes and the resolution of GitHub issues.
