What is Cx language ?

Cx is an open-source programming language in active development, focusing on safe systems programming with a custom compiler backend emphasizing IR for loops, data layouts , and ABI stability toward 0.1.

When will Cx 0.1 release?

No firm date, but backend clears Phase 8/10 blockers; test runner and errors lag. Q3 2026 plausible if momentum holds.

How does Cx backend progress compare to Rust?

Faster solo pace mirrors early Zig/Rust, but leaner scope — loops and layouts locked quicker, though 0.1 basics only.
