BlackBerry has released a new build for developers, with the gold release of BlackBerry 10.2.1 SDK.

BlackBerry says “this new SDK OS includes various fixes as well as our updated BlackBerry Runtime for Android apps, which we debuted in November as part of the 10.2.1 SDK OS beta.

Also, long-running headless apps will be published in BlackBerry World for the first time once BlackBerry 10.2.1 begins rolling out in the near future to BlackBerry customers across the globe.”

Developers, get started testing your app with the latest 10.2.1 SDK and download the latest 10.2.1 Autoloader for your device and the new BlackBerry 10 simulator.
