On 5th of October on biggest Czech open source conference, we released an important milestone in our Turris OS development – Turris OS 4.0. This release based on OpenWrt 18.06 spent quite some time in various forms of testing. It completely changes how we make our releases and we are now much closer to the upstream then we’ve ever been. Everything had to be rebuilt from scratch so it was a huge task to move away from the old way of doing stuff and we took the opportunity to get rid of some of the skeletons in our closets.

Because of that, some of the features available in 3.x might still not present in 4.0. But because 4.0 is the new main development branch, it also has some features not present in 3.x like Storage plugin with support for multiple drives and Nextcloud.

It is the system that is already available on Turris MOX and will be available on newly sold Turris Omnia as well. We are still working on automatic migration path from Turris OS 3.x, but we already have a pretty easy way how to reflash your router manually to Turris OS 4.0.
