# Versions & compatibility

> Current SDK versions per platform and the async model each one uses.

Each SDK is released **independently**, so versions differ per platform. Pin the version listed below for your platform, and confirm the latest in Nexus before upgrading.

## Identifying the running build

Each request the SDK sends to the Validation Gateway identifies the SDK build, so you can confirm which version a device is running from your logs. On the web, `getInfo()` returns the host version and capabilities.

## Compatibility notes

* The Kotlin and Java desktop packages share a Java namespace — [depend on exactly one](/distribution/package-matrix).
* The web SDK requires a compatible **browser extension** and **native host** installed on the machine; keep all three in step when upgrading.
