Breaking

  • WASM engine migrated from Extism to wasmtime Component Model. Capsules must be rebuilt targeting wasm32-wasip2. The #[capsule] macro now generates impl Guest + export!() instead of extern "C" exports. The ABI is completely different — existing .wasm binaries will not load. (#27)
  • All &[u8] parameters changed to &str. IPC topics, KV keys, filesystem paths, and uplink params now require UTF-8 at compile time (was runtime validation). (#31)
  • Approval API simplified to OS permission model. approval::request(action, resource) -> Result<bool> replaces the 3-param version with RiskLevel. Removed RiskLevel, ApprovalDecision, ApprovalResult. Capsules declare what they want; the kernel classifies risk. (#31, astrid-runtime/astrid#641)
  • Interceptor errors halt the chain. The #[capsule] macro returns "deny" on error (was "error" which the kernel silently treated as "continue"). (#27)
  • CallerContext fields corrected. session_id → source_id (capsule UUID), added timestamp. (#27)
  • identity::link returns Result<()>. Was Result<Link> with empty linked_at field. (#27)

Removed

  • ipc::publish_bytes, ipc::publish_msgpack, ipc::poll_bytes, ipc::recv_bytes — use typed publish/publish_json/poll/recv. (#31)
  • uplink::send_bytes — use uplink::send. (#31)
  • net::bind_unix(path) — use net::bind_unix() (no path arg). (#31)
  • hooks::trigger(&[u8]) — now trigger(&str) -> String. (#31)
  • process::ProcessRequest, SubscriptionHandle::as_bytes(), host_result.rs, cron module. (#27, #31)
  • extism-pdk and rmp-serde dependencies. (#27, #31)

Added

  • wit_events! proc macro. Reads a .wit file and generates Rust pub struct / pub enum definitions for every named WIT record and enum, with Serialize + Deserialize + PartialEq + Clone + Debug derives and /// doc comments preserved. Capsule authors write WIT once — the same file feeds wit_events!() for Rust types and the core's wit-parser for JSON Schema extraction. Zero type duplication. (#32)
  • Serde derives on all WIT-generated types. astrid-sys now passes generate_unused_types: true and additional_derives: [serde::Serialize, serde::Deserialize, PartialEq] to wit_bindgen::generate!. (#32)
  • Typed IPC poll/recv. ipc::poll() / ipc::recv() return PollResult { messages: Vec<Message>, dropped, lagged }. (#31)
  • HTTP Response exposes status + headers. Response::status(), Response::headers(), Response::is_success(). (#31)
  • log::trace(). All log functions now return () (was Result). (#31)
  • Component Model test capsule. examples/test-capsule/ validates the full SDK→macro→WIT pipeline, including wit_events! generated types used in ipc::publish_json(). (#27, #32)
  • Mandatory WIT exports. #[capsule] macro generates all 4 guest exports with no-op stubs for unused ones. Solves astrid-runtime/astrid#638. (#27)

Changed

  • astrid-sys uses wit_bindgen::generate! instead of extism_pdk FFI. (#27)
  • SysError::HostError wraps String (was extism_pdk::Error). (#27)
  • Handle types internally wrap u64 with consistent id() accessor. (#31)
  • http::Response fields private with accessor methods. (#31)
  • interceptors::poll handler receives typed &ipc::PollResult. (#31)
  • State not persisted on tool error. Install/upgrade/run errors logged. (#27)
  • #![forbid(unsafe_code)] on astrid-sdk. (#27)
