Ultima Online’s Publish 125 has moved forward on the test servers. On October 28, 2026, the UO Team pushed the second update for the publish to Test Center 1 (TC1), and the main addition is a new holiday activity named Wintertide.
The announcement itself is brief. It confirms that Wintertide is part of this build and directs players to the full publish notes for details on how the activity works, what it involves and any rewards attached to it. The short post doesn’t describe the event, so anyone curious about the specifics will want to read those notes before logging in.
What this means for players
TC1 is where Ultima Online puts upcoming changes in front of the community before they go to the production shards. Content on the Test Center is still a work in progress, so details can shift between test updates as the team gathers feedback and fixes bugs. That makes this a good time for players who enjoy seasonal content to take a look and report anything that seems off.
A few practical points if you plan to test:
- Patch your client first. The team specifically reminds players to update their client before trying any new content on TC1.
- Read the publish notes. They hold the full list of changes in this update, including how Wintertide works.
- Remember it’s a test environment. Progress on TC1 doesn’t carry over to your characters on the live shards.
When will it go live?
The announcement doesn’t give a date for Publish 125 to reach the production shards, and it doesn’t say whether more TC1 updates will follow before then. Given the winter theme, players will likely be watching for news as the holiday season approaches, but until the UO Team confirms a schedule, the test server is the only place to see Wintertide in action.
For now, the advice is simple: patch up, check the official announcement and the linked publish notes, and head to TC1 if you want an early look at Ultima Online’s newest seasonal activity.
