Version 1 of the API is now deprecated. We have no plan to deactivate it yet; it will continue to work the same way and will still continue to receive and use our latest user-agent parsing code (ie. new web browsers will still be detected by it), but new API end points build will not be back-ported.
If you currently use version 1 of our API, please read our guide to migrating to Version 2.
