0.2.0 (2026-05-01)

gjsify v0.2.0 is the most comprehensive release to date and marks a major milestone on the road to full Node.js compatibility on GJS.

The @gjsify/fs module is now nearly complete: four consecutive PRs landed cp, opendir, glob, watchFile, statfs, utimes, lchown, FileHandle, and an AsyncIterableIterator-based fs.promises.watch() stream. The WebSocket server implementation is equally complete — with verifyClient, handleProtocols, noServer/handleUpgrade, permessage-deflate, and full Autobahn testsuite coverage. socket.io now runs 20/20 tests on GJS, a direct result of root-cause fixes across events, fetch, http, and stream.

New additions include: MCP support (Model Context Protocol) with server, client, and Streamable HTTP examples; the first phases of ts-for-gir integration, making @ts-for-gir/cli run fully on GJS for the first time; a new framework pillar with @gjsify/adw-app; GstHTMLVideoElement for GStreamer-backed video playback; and Playwright-based browser tests for Web/DOM packages.

On the performance side, per-frame GC allocations in the WebGL stack and the Excalibur demo have been significantly reduced.
