May 2025 performance summary for tschneidereit/wasm-micro-runtime. Key delivery: WebAssembly SIMD enhancement introducing WASM_OP_SELECT_128 for conditional selection of two 128-bit SIMD values. Implemented in both the AOT compiler and the fast interpreter to ensure consistent support and broaden SIMD capabilities. Major bugs fixed: none reported this period. Business impact: expands SIMD capabilities, enabling conditional vector operations and paving the way for performance improvements on vector workloads; improves cross-path consistency, reducing maintenance risk. Technologies/skills demonstrated: low-level SIMD implementation, WASM_OP orchestration, cross-path development (AOT + interpreter). Commits affected: 129dc3a30f21ee4624fab46c410438d0b6366333.

Monthly summary for 2024-11 focused on wasm-micro-runtime feature delivery. Key achievement: Enable WebAssembly Reference Types by default in WAMR; other engineering tasks included docs and build configuration updates. Overall impact: simplifies builds and improves module compatibility with reference types; aligns with WebAssembly specs and business value by reducing build-time flags and enabling advanced features out-of-the-box.

October 2024 monthly summary for bytecodealliance/wasm-micro-runtime. Delivered a critical memory-safety fix addressing out-of-bounds accesses after memory.grow in non-AOT/non-threads builds, by replacing a generic linear memory size retrieval with a dedicated macro to compute the size accurately. This change prevents crashes and undefined behavior during dynamic memory growth and enhances runtime stability across configurations.
