Blog Urbit Community Update - January 2023

Jeremy Tunnell at

There’s been a lot going in the Urbit world, let’s get into it.

Groups & Talk Update

Over the past few months, there’s been a major overhaul of Urbit’s most developed application, Groups. This comes courtesy of Tlon, who have been hard at work on their application suite. Through a series of network updates, users across the network performed a data migration when they updated their urbit, and the original Groups transformed into then new Groups and Talk apps.

In the centralized application world, running a data migration at scale is the domain of back-end developers or DevOps specialists. On Urbit, countless individuals installed an update and it happened automatically.

This first of its kind update required a significant amount of work not only to the Groups interface, but to the Arvo kernel itself. We’d like to congratulate everyone who helped to make it happen.

This major migration didn’t happen without hiccups, however. If you’ve been having issues with your ship then we’d recommend checking out this post on troubleshooting common issues.

Network Updates

In Urbit core development news, the Urbit Foundation has now officially taken over responsibility of the release process from Tlon. From here on out there will be weekly releases to the network, every Tuesday. Reminder: if you’re a developer and wish to stay apprised of the detailed changelog, we recommend subscribing to the dev mailing list.

Over the past few months several updates have been released that have delivered projects that are significant milestones in developer experience, release frequency, and backwards compatibility. These include:
