📖 ECMA-419 has been completely reworked using Ecmarkup, the same system used for ECMA-262 and ECMA-402.

That gives it a familiar look and feel for JavaScript developers, while integrated search, permalinks, pinning, and contextual highlights make it easier to navigate.

📡 Marquee additions are BLE & DNS-SD

BLE
• Central & Peripheral roles
• Build Peripherals with declarative JSON + callbacks
• Web Bluetooth built on Central for web compat
• Supports complex BLE profiles (Apple Media Service)

DNS-SD
• Discover, Advertise, & Claim Names

Next up: Tic-tac-toe on PebbleOS.

Built with the Piu touch UI framework in Alloy.
