New Android Lollipop developer preview and SDK now out
The original developer preview for what was then only known as Android L was announced back in June. The images were updated once in the meantime, in August, when they received support for Google Fit.
And now we're at the third iteration of these images, and almost certainly the last - since Android 5.0 Lollipop is due to become available as a software update for the Nexus 5 and Nexus 7 in the coming weeks.
Right now it's not clear what's new in the just-published images, but hopefully they'll show an Android 5.0 release that's almost finished. That said, they don't represent the final bits of Lollipop, and they're bound to still have some bugs. Hence, if you're not a developer, you should probably stay away from them, and wait for the official software to start rolling out.
Speaking of developers, they will be happy to know that the Android 5.0 SDK is now out too. This allows developers to start working on getting their apps ready for the new OS version. Lollipop comes with 5,000 new APIs. The new SDK follows the preview release from this summer.
