EDG C++ front-end goes public

EDG’s C++ front end will be released as open source on September 30, 2026, with The C++ Alliance acting as its nonprofit home and fiscal sponsor. The move preserves the existing engine, standards conformance, and professional maintenance while opening the code at github.com/edgcpp for public contribution. EDG, a thirty-year production-quality source-to-source front end that underpins many compilers and tools, will remain staffed by experienced maintainers under a continuity-first plan led by John Spicer. The C++ Alliance was chosen for its fiscal-sponsorship infrastructure, in-house C++ compiler expertise, connections to Boost and LLVM contributors, and transparency practices.

Development will use a single public codebase and three parallel tracks: community pull requests reviewed by experienced EDG reviewers; always-open maintenance work by Alliance-hired EDG developers published immediately; and collectively funded larger features paid for by organizations and released to everyone simultaneously. Oversight comes from a Fiscal Sponsorship Committee chaired by John Spicer with user-community volunteers to set priorities and review policies. Funding shifts from annual license fees to tax-deductible contributions, there is no early-access or vendor lock-in, and next steps include executing the sponsorship agreement, inviting community input on the committee, and accepting contributions once the source is public.
