Changelog

Unreleased

Added symbol-based JavaScript host values, including atomic and composite Ferret capability protocols, synchronous and asynchronous iteration, stable object identity, runtime integration, and explicit output serialization.
Added an explicit http.allowLocalhost engine option for trusted loopback access while preserving Ferret's secure HTTP defaults.
Added declarative JavaScript modules through defineModule() and create({ modules }), including asynchronous engine, plan, and session lifecycle hooks.
Added optional FQL namespaces for JavaScript module functions while keeping module registration identity independent.

Replaced Go's WASM HTTP adapter with per-engine browser and Node transports. Node validates and pins DNS results while Ferret policy-checks redirects; browsers allow same-origin requests only and reject redirects.
Made plan compilation and session creation asynchronous across the JavaScript/WASM boundary.
Added cancellation options for compilation and session creation.
Exposed synchronous closed metadata on engines, plans, and sessions.
Unified legacy create({ functions }) registration with the Ferret module bootstrap path while keeping the public shorthand backward-compatible.

Migrated the compiler and runtime to Ferret v2.0.0-alpha.30.
Replaced the v1 JavaScript API with explicit Engine, Plan, and Session lifecycles.
Replaced the Go 1.12 runtime fork with the official runtime matching the build toolchain.
Added ESM, CommonJS, Node.js, and browser package exports.
Updated the build and test stack to TypeScript 5, tsup, Vitest, Playwright, and GitHub Actions.

Immutable synchronous and asynchronous JavaScript host functions.
AbortSignal cancellation.
Named sources, plan parameter metadata, custom WASM sources, and deterministic cascading cleanup.
Node.js and Chromium integration coverage.

Ferret v1, mutable function registration, exec, destroy, the custom wasm_exec.ts implementation, legacy polyfills, TSLint, Husky, and Travis CI.
