Patch coverage on this page stops at 1.0.4 as of the verification date. Newer builds and full bullet lists — the Steam news hub is the authoritative source. Related systems deep-dives: tools and automation, multiplayer. Launch-day context sits on the release page.

What did 1.0.3 change?

Condensed from the official announcement:

Saves

• Heavily cleaned bases that looked corrupted load again
• Damaged saves repair automatically from backup/snapshot on load
• Saves are checked before replacing the previous file

Multiplayer

• Shared upgrades via the host upgrade matrix; anyone’s purchase upgrades everyone
• Host kick / ban / unban under ESC → Your Crew
• Crew-built splitters and mergers work
• All players must be on 1.0.3 to play together

Performance & building

• Studio-claimed higher frame rates on big bases; smoother driving and teleports
• Horizon culling for ground behind the Moon
• Splitter/merger snapping; belt capsule placement; multi-foundation machines
• Deposit intake pays exactly what the screen shows

Vehicles

• Any garage can recall/store/upgrade vehicles
• Demolishing a garage no longer deletes stored vehicles

What did 1.0.4 change?

Condensed from the official announcement:

New / moved player tools

• Night Vision Goggles ($350); N cycles lamp → goggles → off
• Improved Moon Map with waypoints and robot filters
• Teleport Panel between discovered stations
• Suit HUD icons; helmet lamp upgrades moved to the supply wall
• Capsule Catcher capacity 100 kg with visible dust in glass

J.O.O.N.A.S.

• Launches capsules from the field to the nearest catcher
• Faster hex cleaning; smarter pathing; works with no nearby players
• Full-bin warning and sector tracking UI

Saving & backups

• Much faster saving/quitting on large bases
• Up to 5 automatic backups per save slot (session + every 30 minutes)
• Backup folder: AppData\LocalLow\DragDropGames\MoonSweepers\Backups
• Automatic repair after damage/crashes
• Saves made in 1.0.4 cannot open in older versions

Multiplayer & fixes

• Shared cleaned-ground sync (including robot trails)
• Shared belt building for splitters/mergers
• AMD defaulting to DirectX 11; optional -force-d3d12
• Steam Deck / older Proton startup fix
• Long list of machine, foundation, map, and vehicle bug fixes

Developer context between the patches

The October 24 “Message From the Developers” apologized for launch instability, confirmed a two-person team, and listed shared upgrades, performance, saves, host moderation, and belt fixes as already shipping, with J.O.O.N.A.S. idle behavior called out as a near-term priority — matching what 1.0.4 emphasized the next day.

Machine prices and Catcher capacity cross-checks for builders live in the data hub, Capsule Catcher, and J.O.O.N.A.S. pages.
