wasmCloud News: GitHub Actions Toolkit, Wash Attestation & WebGPU

For the latest WebAssembly news, the October 1, 2025 wasmCloud community call walks an end-to-end demo of a new GitHub Actions toolkit for the wash CLI — built around supply-chain security with binary attestation, SBOM generation via cargo auditable, and a language-agnostic build/publish flow. Bailey Hayes also previews a new non-interactive mode for CI and proposed volume mounts for wash plugins, while Colin Murphy and the team explore WebGPU, hybrid AI inferencing, and the road to the next version of wasmCloud and the Wasm component model.

WebAssembly on Kubernetes: the New wasmCloud Runtime Operator & WASI P3

The September 24, 2025 wasmCloud community call is all about running WebAssembly on Kubernetes. Lucas Fontes walks through a new Kubernetes-native runtime operator for wasmCloud v2 that stores all workload state in Kubernetes via custom resources (CRDs), aligns naming with pods, replica sets, and deployments, and replaces external capability providers with secure in-process host plugins. Bailey Hayes covers a wave of wash and setup-wash-action improvements for the next major version, and shares that Wasmtime has shipped the first WASI P3 release candidate.

wasmCloud V2: The Wasm Component Model & a Simplified Host

The September 17, 2025 wasmCloud community call is a deep dive into wasmCloud V2 — also called wasmCloud Next — Brooks Townsend's proposal for a "radical simplification" of the platform. He walks through a pull request that introduces a consolidated wasmcloud crate (merging the host, runtime, and core libraries), a simplified Host API focused on scheduling workloads built from WebAssembly components, host plugins that replace built-in capability providers and make the wRPC transport opt-in, and in-process component-to-component calls for components running on the same host. Brooks presents C4-style architecture diagrams for the new model, and Eric Gregory previews a next version of the docs.

Wasm Component Model: Plugins, Shared Memory & WASI 0.3

The September 10, 2025 wasmCloud community call started as "the quickest wasmCloud Wednesday ever" — no agenda, with the team heads-down on the last items of the Q3 roadmap — and then turned into a wide-ranging hallway conversation about the hard edges of the Wasm component model. Brooks Townsend, Colin Murphy, and Victor Adossi dig into why adding system time-zone support to Wasmtime takes a year and a half, how a wasmCloud host plugin could route around runtime bottlenecks, Christophe's shared-memory proof of concept, and why first-class functions in WIT are the missing piece for generating polyglot SDKs — all while looking ahead to what WASI 0.3 (Preview 3) unlocks.

In-Process Component Calls & the Wasm Component Model

The September 3, 2025 wasmCloud community call digs into the Wasm component model as the foundation for a leaner, more modular runtime. Brooks Townsend walks through in-process component-to-component calls — letting two components on the same host talk directly instead of going over wRPC/NATS, dropping latency from hundreds of microseconds to single-digit nanoseconds — and a broader effort to shrink the wasmCloud host's responsibility down to component lifecycle management, with capabilities provided through an optional plugin layer. Bailey Hayes closes with a quick demo of new shell auto-completions in the wash CLI.
