2026-05: Focused on improving compiler diagnostics for LEN parameters in parameterized derived types (PDT) in lfortran/lfortran. Implemented a targeted diagnostic that aborts with a specific error message for unsupported features during semantic analysis, improving user feedback and reducing support overhead.

Monthly summary for 2025-10 (emscripten-core/emscripten). Delivered a feature that maps the -ffast-math compiler flag to wasm-opt --fast-math during linking, enabling aggressive floating-point optimizations and improving runtime performance. No major bugs fixed this month. Overall impact includes performance uplift for FP-heavy wasm workloads and smoother flag propagation through the linker passes. Technologies demonstrated include WebAssembly, wasm-opt, Binaryen, linker passes, and C/C++ flag handling.
