SDK Versioning

DropOnAir uses semantic versioning to ensure backward compatibility and smooth upgrades.

SDK packages are published per platform, so JS, Android, and iOS version numbers can differ while protocol compatibility stays aligned.

Version constants

import { SDK_VERSION, PROTOCOL_VERSION, PAYLOAD_FORMAT_VERSION } from '@droponair/sdk-js';

console.log(SDK_VERSION);            // e.g. "0.3.1"
console.log(PROTOCOL_VERSION);       // e.g. 4
console.log(PAYLOAD_FORMAT_VERSION); // e.g. 1
