Although MycrofOS is still in alpha phase, from alpha version 4 and onwards it is already in quite a usable state for daily usage as consumer ready opensource privacy minded voice assistant / smart speaker. Most development in the early stages has been done on the Raspberry Pi 3B, however recently the Raspberry Pi 4 with 2 GB memory is added to that. Downloads for both systems are currently being provided.
If you would like to checkout the development or would like to help in ANY way, please head over to the MycroftOS Github page. Am more than happy to receive issues/bugreports, pull requests or any other possible contribution you might be able to give.

Make sure you grab the latest version as possible. Development continues and each and every version bump fixes a number of issues or adds a number of features. At the moment there is no clear changelog available for the old builds. For the next build (alpha7), I will start creating some sort of changelog.
