New Interfaces

The past few months have seen the release of new versions of Landscape, the interface that ships with most Urbit builds, as well as the desktop application Scene from Tirrel, and the alpha of Realm from Holium.

These ‘interfaces’ are like Linux distributions; they utilize Urbit’s core and include additional features to enhance their functionality. As Urbit continues to develop, we can expect more interfaces, and as a developer it’s important to think about what type of Urbit interface offers you useful functionality and integration opportunities.

Core Development

Things have been happening fast. Tlon has announced their intention to focus on Groups and the related tool suite, and Urbit Foundation is in the process of managing core development and releases. Highlights of this process include:

Because of this increase in pace, we will drop the “Upcoming PRs” section from this newsletter. You’re liable to see it in production before we can get it to press!

Current and upcoming tasks on the Urbit Roadmap include rolling out solid-state subscriptions, kelvin shims, and event log truncation. Also watch for 8GB loom and userspace permissioning soon.

    Hi Jeremy, I've been following your Urbit outreach work for some time, which helped me get on the platform. I have created a portal to educate people about Urbit (, criticism and suggestions are very welcome if you have time to take a look. Best regards
