Feb 1, 2026February 2026 focused on stabilizing wasmCloud for a robust RC7, expanding capabilities with a PostgreSQL plugin, and elevating code quality for maintainability and reliability. Delivered RC7 readiness by updating version references in Cargo.toml and runtime-operator values.yaml, with Cargo.lock synchronization to ensure a clean release path. Introduced a PostgreSQL plugin enabling connection pooling and prepared statements for database interactions. Implemented broad internal improvements across observability, testing framework structure, CLI path handling, and the WASI runtime to improve maintainability, reliability, and developer productivity. These efforts establish a solid baseline for release stability, performance, and future iterations.

Nov 1, 2025November 2025 (2025-11) overview for wasmCloud/wasmCloud focused on delivering user-facing capabilities, hardening the platform, and improving release velocity. Key features introduced include a new wash host command, Docker Canary image support, and improved runtime integration by bundling HTTP into the Runtime. Major reliability and performance improvements were achieved by separating NATS control and data connections, locking to the PR to avoid unintended merges, and enhancing the release process (Docker release tagging, protoc in release workflow). Platform capabilities were extended with WASI WebGPU support and a NATS blobstore, while maintenance work covered CI stability, linting alignment, and tests across the batch. Observability and operational visibility were improved through enhanced washlet action logs and a host startup message. These efforts collectively improve developer experience, release velocity, security, and runtime robustness.

Jun 1, 2025June 2025: wasmCloud/wasmCloud delivered a major runtime customization enhancement by introducing flexible runtime linking via new_with_linker and publicly exposing Ctx to enable external access to runtime state. This work clarifies how Wasmtime interfaces can be custom linked and how Ctx interacts with WASI, HTTP, and WRPC contexts, underpinning more advanced integration scenarios and component workflows (e.g., Component::new_with_linker). Documentation updates accompany the feature to improve developer onboarding and API discoverability. No major bugs were reported or fixed this month; focus was on feature delivery and documentation.
