EDG C++ front-end goes public

On September 30, 2026, the source for EDG's C++ front end becomes available for public use, with The C++ Alliance assuming the role of its nonprofit organization. The engine and standards remain unchanged, but the transition signifies a shift in stewardship. EDG's front end has been the backbone of C++ compilation for three decades, powering various compilers and tools.

This article delves into EDG's origins, key individuals, milestones, and the compilers it has influenced. If you have a story to share from this history, submit an issue on the project's repository. Upon the source's public release on September 30, 2026, continuous professional maintenance will be crucial. The C++ Alliance, a nonprofit with fiscal-sponsorship expertise, C++ compiler professionals, and strong ties to the C++ standards and Boost communities, will serve as EDG's new home.

EDG's development will follow three tracks: user community contributions, ongoing maintenance, and funded features through collectively funded resources. A single codebase will be accessible to everyone, with contributions evaluated and integrated consistently across all tracks. The Fiscal Sponsorship Committee oversees the process, chaired by John Spicer and comprising volunteers from the EDG user community.

Users can participate in shaping the committee and development priorities. The fiscal sponsorship agreement is prepared for signing prior to the transition date, and users can seek guidance on the hand-off process. EDG users are encouraged to provide feedback on the committee's composition and development priorities. Once the source is public, bug fixes and new features from users can be submitted as pull requests on GitHub. To stay updated on the transition, watch the EDG organization on GitHub.
