In 2024, the WAMR community saw many thrilling advancements, including the development of new features, increased industrial use, and an improved experience for developers. Passionate developers and industry professionals have come together to enhance and expand WAMR in ways we couldn’t have imagined. From exciting new tools to a growing community, there’s a lot to be proud of. Let’s take a closer look at the key highlights of WAMR 2024, showcasing the community’s efforts, new features, and the establishment of the Embedded Special Interest Group (ESIG).

Each December the Bytecode Alliance conducts elections to fill important roles on our governing Board and Technical Steering Committee (TSC). I’m pleased to announce the results of our just-held December 2024 election, in which our Recognized Contributors (RCs) selected three Elected Delegates to the TSC and one At-Large Director to represent them on the Alliance Board.

Wasmtime is a lightweight WebAssembly runtime built for speed, security, and standards-compliance. December’s v28.0 release brings enhancements including a new option for optimization at compile-time, a new first-class type for Cranelift’s domain-specific language (DSL), and more.

Portability is among the first properties promoted on WebAssembly’s official homepage:

This month’s v27.0 release of Wasmtime—the fast, secure, and standards-compliant WebAssembly (Wasm) runtime—includes enhancements such as completed support for the new Wasm garbage collection proposal, a PyTorch backend for wasi-nn, link-time feature gate configuration for unstable WIT APIs, and more.

Wasmtime is a fast, secure, and standards-compliant WebAssembly runtime. The latest v26.0 release includes enhancements such as implementation of the “table64” extension, a new wasmtime completion subcommand, ARM64 Windows support, and more.

Wasmtime is a lightweight WebAssembly runtime that is fast, secure, and standards-compliant. Today’s release of Wasmtime v25.0 brings enhancements including extended constants, WASI 0.2.1 support, and user stack maps.

As part of implementing the WebAssembly garbage collection proposal in Wasmtime, which is an ongoing process, we’ve overhauled the stack map infrastructure in Cranelift. This post will explain what stack maps are, why we needed to change them, and how the new stack maps work.

The Bytecode Alliance is pleased to invite you to the next installment in our ongoing Plumbers Summit event series, each designed to bring our members and community contributors together to help set strategic direction and plan efforts for the coming year. Our next Summit will be September 26 and 27, 2024 at the Microsoft Visitor Center in Redmond, Washington. Seating for the in-person session is limited but the event will be live streamed online to support full remote participation.

If you’re a .NET/C# developer, componentize-dotnet makes it easy to compile your code to WebAssembly components using a single tool. This Bytecode Alliance project is a NuGet package that can be used to create a fully AOT-compiled component from a .NET application—giving .NET developers a component experience comparable to those in Rust and TinyGo.
