Buildlang 1.4.0 defines checked fixed-width integer arithmetic and ships the merged portable stdio, match-result lowering, and VS Code dependency-lock repairs.
- Plain fixed-width integer addition, subtraction, multiplication, and compound assignments use checked semantics. Constant overflow is diagnosed; runtime overflow uses the arithmetic panic path. Explicit checked, wrapping, and saturating operations remain distinct.
- Option/Result match expressions obtain concrete result types from context or arm payloads. C and Rust print lowering preserve stdout versus stderr intent.
- The compiler manifest and lockfile identify version 1.4.0. Two intentionally retained scientific-runtime report fields have focused dead-code annotations for strict-warning builds.
The C path remains primary. Rust, LLVM, WASM, SPIR-V, and native experimental backends retain their documented limitations. LLVM function-style formatting is unsupported and fails closed. This release does not establish performance superiority or complete backend parity.
Validation: the local full strict-warning test suite passed with 1,818 passed, zero failed, and 11 ignored. Formatting, repository-art verification, and the strict-warning optimized build passed. The release commit also passed CI lint, art, Windows/Ubuntu tests and optimized builds, plus the workflow's compile and negative-program checks.
This GitHub source release does not publish a package registry artifact or a prebuilt compiler binary.
