Community Calls
wasmcloud:nats on main, Custom Go Host Plugins, Warm Pool Reclaim
September's first wasmCloud community call is a landing-week call: the wasmcloud:nats interface and its native host plugin are on main, and with them a single unified plugin configuration block, a new guest invocation duration metric, and a run of hardening fixes for draining, unbinding, and concurrent starts. Jeremy Fleitz demos a custom Go host plugin built with componentize-go, Eric Gregory ships two reference docs, and Bailey Hayes walks the warm-pool reclaim knobs that make wasm runtime autoscaling work on a real Kubernetes host — while Liam Randall reports roughly 100 workloads running in 50–60 MB of memory.
wasmCloud 2.8 Ships, a Native NATS Host Plugin, and Seven Messaging Patterns Under Test
The August 26, 2026 wasmCloud community call opens the day after wasmCloud 2.8 shipped with epoch cancellation and an async wasmcloud:messaging API. Jeremy Fleitz demos the native NATS host plugin (PR #5494) — Core NATS, JetStream, and KV as first-class host interfaces with per-workload credentials and subject grants — Eric Gregory walks the new concurrency and connections doc, and Liam Randall presents a seven-pattern NATS test matrix run on WebAssembly on Kubernetes, where six of seven patterns are clean at stock settings and a deliberately OOMed host still lost zero JetStream messages.
Go WebAssembly Toolchains Compared, a WASI SDK GitHub Action, and Top-Level WIT Types
The August 19, 2026 wasmCloud community call is a tour of the Go WebAssembly toolchain landscape and the standards work underneath it. Eric Gregory presents the rewritten Go language guide — TinyGo versus componentized Go, trade-off by trade-off — and Bailey Hayes makes the case for skating to where the puck is heading: componentize-go, with cooperative threading for goroutines on the horizon. Victor Adossi ships a WASI SDK GitHub Action that turns C/C++-to-Wasm builds into two steps of CI, Yordis Prieto lands top-level types in the Wasm component model, and newcomer Adam de Delva introduces BTR's Wasm-powered compute portal.
wasmCloud 2.7 Ships 13.6x Concurrency, WIT Annotations Take Shape, and an OCI Registry Made of Components
The August 12, 2026 wasmCloud community call opens with Bailey Hayes unpacking wasmCloud 2.7 — max concurrency on instance pools (13.6x in her best-case benchmark), a hardened OCI registry component, and maps and implements enabled by default in the Wasm component model after a W3C WASI subgroup vote. Aditya Salunkhe walks through his epoch-interruption work for canceling runaway guest code, and Yordis Prieto lays out the plan for WIT annotations — a change that would let WIT express read/write capability views, Protobuf-style validation, and more, making WIT effectively a superset of Protobuf.
