Google IO kicks off tomorrow and just in time for the developer conference, Google has dropped the latest Developer Preview (Dev Preview 4 for those playing at home) which includes full support for the Google Assistant SDK.

It’s all about development boards this preview, shoring up existing support and adding more support for things like the AIY maker projects which Google launched last week. The support expands Android Things to development boards beyond the Raspberry Pi 3, Google says:

We are now adding a new Board Support Package for the NXP i.MX7D, which supports higher performance than the i.MX6UL while still using a low power System on Module (SoM) design. Support for Inter-IC Sound Bus (I2S) has been added to the Peripheral I/O API, now enabling audio drivers to be written in user space for sound hardware connected via an I2S bus. The AIY Voice Kit sample demonstrates how to use I2S support for audio. We have also provided the ability for developers to enable/disable Bluetooth profiles at run time.

Google has released the code for Android Developer Things Dev Preview 4 over on GitHub and if you want to download the new Dev Preview, you can hit their download page here.
