Quick answer

The developer's 30 October announcement targets December 2026 for Moon Sweepers update 1.1. No exact release day is provided. As of the official feed check on 8 November 2026, 1.1 remains a plan and 1.0.5 is the latest released patch in that feed. S05S17

Is there a confirmed 1.1 release date?

There is a target month, not a confirmed calendar day in the reviewed announcement. Do not treat a December placeholder or a community prediction as an official date.

A roadmap posted after a patch is newer news, but it is not a newer playable build.

What is planned for 1.1?

The announcement describes further production chains, materials, equipment, automation, buildings and later-game progression. The developer says the work is in development and may change. S05

These are broad planned directions. The source does not establish final machine prices, recipes, upgrade costs or the resulting best factory layout. Current guides should continue using released mechanics until the developer publishes the update and its details.

What can I use in the current version?

Version 1.0.5 already includes the catcher-group routing change, Move Mode, full removal refunds and large-base packing fixes. The earlier patches include local automatic backups and the shared host Upgrade Matrix. Those are documented released changes, separate from 1.1's planned content.

Use current patch notes for the full version history, move a conveyor layout for current building controls, or robots and catcher ratios for current reception rules.

How to check whether 1.1 has shipped

Open the game's official Steam announcements and the developer feed. Look for a released 1.1 patch announcement, then compare it with the installed game version. Reading the old roadmap alone does not confirm shipment.

Before a major update, preserve a separate copy of local world data. No forward or backward save-compatibility guarantee for 1.1 is established by this roadmap. The known 1.0.4 incompatibility with older builds should not be extrapolated into an invented 1.1 rule.

For crew planning while waiting, see co-op host settings and shared upgrades. This page records the dated official plan; it does not predict an unannounced release day.
