After entering Developer Preview as a beta last month, Google today announced the second release of Android 8.1. “Near-final system images for final testing” are available today for the latest Pixel and Nexus devices and come ahead of next month’s public launch.

Android 8.1 Oreo and API level 27 introduces a number of new features for developers, including a Neural networks API that allows for hardware acceleration of on-device machine learning. DP2 specifically activates the Pixel Visual Core which was absent for last month’s preview. This version also features the November security patch.

There are also notification behavior changes, new WallpaperColors API, and Programmatic Safe Browsing actions. For lower end devices there is a Shared memory API and Android Wear also gets a handful of new features. To learn more, read our post covering the new under-the-hood features in DP1.

Meanwhile, check out our updating gallery on all the visual and experience changes in Developer Preview 1 for Pixel and Nexus devices.
