nx.js v0.0.66

🔊 Audio Playback

• ⁠New ⁠ Audio ⁠ class — Play MP3, WAV, and OGG Vorbis files using the familiar HTML5 ⁠ Audio ⁠ API.

🌐 WebApplet

• Switch.WebApplet ⁠ — Launch a non-blocking web browser overlay with JavaScript ↔️ Switch IPC messaging via window.nx
• ⁠Offline HTML support — Bundle HTML apps directly into your NSP using the new ⁠ htmldoc: protocol. Just drop files in a htmldoc/  folder and reference them with⁠ htmldoc:/index.html  — the NCA structure is handled automatically.
• ⁠Configurable options — Control all WebApplet settings (display mode, footer, pointer, etc.) via an options object passed to applet.start()

🔐 Web Crypto API (Complete!)

•⁠ ⁠Full ⁠ SubtleCrypto ⁠ implementation:

• HMAC — sign/verify with SHA-1/256/384/512
• AES-GCM — encrypt/decrypt
• PBKDF2 & HKDF — key derivation
• ECDSA — sign/verify (P-256, P-384)
• ECDH — key derivation
• RSA — RSA-OAEP, RSASSA-PKCS1-v1_5, RSA-PSS
• Key management — ⁠ generateKey, importKey, exportKey, wrapKey ,  unwrapKey  (raw, PKCS8, SPKI, JWK formats)

🔒 TLS Certificate Verification

• ⁠HTTPS connections now verify certificates against the Switch system CA store — no more blindly trusting everything

🎨 Canvas 2D

• ⁠Gradient support — createLinearGradient() and createRadialGradient() with color stops now work

🧩 WebAssembly

• ⁠⁠WebAssembly.validate() implemented
• ⁠ Memory.buffer is now cached for better performance

🔧 Runtime Fixes

• ⁠Fixed stat() timestamps (were returning 0)
• ⁠Fixed memory leaks in string handling
• ⁠Fixed poll list iteration safety
• ⁠Fixed vibration handle leak
• ⁠Enabled SO_REUSEADDR for sockets
• ⁠Fixed async initialization ordering
• ⁠Fixed NSP crash caused by npdmtool debug flag encoding

🧪 Testing Infrastructure

• ⁠New host-platform conformance test harnesses for Canvas 2D, WebAssembly, and Compression Streams
• ⁠Image snapshot testing for canvas output
• ⁠Consolidated test runner using real runtime code

📦 Other
