wasd 0.3.0

WASD: Wasm And Dart System / WebAssembly System for Dart.

0.3.0

• Stabilize Preview1 command-module support with real host filesystem preopens across Dart VM and Node.js, including host-backed file, directory, symlink, and timestamp behavior.
• Record the current WebAssembly core and WASI Preview1 conformance gates in an executable TODO under doc/.
• Add Preview2 component host/import coverage for standard wasi:io, wasi:cli, wasi:filesystem, and wasi:sockets packages.
• Add Preview3 component host/filesystem/async-profile scaffolding without claiming full Preview3 runtime coverage.
• Keep unsupported Preview2 and Preview3 operations explicit through WASI error results instead of reporting fake success.

0.2.0

• Restructure the package around explicit package:wasd/wasm.dart and package:wasd/wasi.dart entrypoints, with package:wasd/wasd.dart re-exporting both surfaces.
• Ship the pure Dart WebAssembly runtime split into JS and native backends with regression-tested compile, instantiate, validate, typed exports, memory/table/global/tag wrappers, and host import support.
• Replace the old WASI API with a single WASI Preview1 surface aligned with the current 0.2 package design, covering command-style execution plus virtual filesystem basics on native and browser runtimes.
• Refresh examples and docs around the new 0.2 API, including the Flutter DOOM demo under example/doom.

0.1.0

• Promote the package to the first minor release with a stable public entrypoint at package:wasd/wasd.dart.
• Expand runtime coverage with regression-tested module execution, host imports, and validator behavior.
• Ship WASI Preview1 support with WasiPreview1 and WasiRunner execution paths.
• Add component-model decoding/instantiation and canonical ABI invocation helpers.
• Improve tooling and examples, including conformance runners and the Flutter example/doom demo.

0.0.1

• Rename project to WASD (Wasm And Dart System / WebAssembly System for Dart).
• Publish initial open-source package structure on pub.dev.
• Add lib/wasd.dart as the primary package entrypoint.
• Update examples, tests, and demo app imports to package:wasd/wasd.dart.
• Keep lib/pure_wasm_runtime.dart as a compatibility alias.
