Hi,
This is a heads up about upcoming ABI breaks in std::expected and parts of <ranges> in LLVM 18. I am centralizing all the details in [libc++] Vendor communication: upcoming ABI breaks in std::expected and parts of <ranges> · Issue #70820 · llvm/llvm-project · GitHub to keep things in a single location. Please monitor that GitHub issue for any updates to this topic.
Cheers,
Louis
