Subgraph OS Announcement
We are happy to announce that Subgraph is to receive support for 12 months of Subgraph OS development from the Open Technology Fund.
This means that we will be able to focus our efforts over the next year on development exclusively.
Our current areas of focus are:
Oz, our framework for application isolation
Tooling and automation for builds and tests of Subgraph OS packages as well as for the base OS image. We are working towards a downloadable ISO as soon as possible.
All of our code is to be hosted on Github, though for now everything there is very alpha. We invite the community to check it out.
