Ostranauts Update Guide: Patch Notes and Version Changes

Stay current with every Ostranauts update guide change. Track the 0.13, 0.14, and 1.0 patches, new features, and tips for adapting your playthrough.

Ostranauts has shipped more than two dozen major patches since its 2020 Early Access launch, and every Ostranauts update guide worth reading treats those patches as living documentation rather than static changelogs. With Version 1.0 dropping on August 3, 2026, players finally have a stable baseline, but the 0.13, 0.14, and 1.0.0.7 builds each shipped meaningful system changes that can break old saves or shift dominant strategies. This Ostranauts update guide walks you through what changed, how to adapt your loadouts, and where to verify any data point against community sources.

What Is the Ostranauts Update Guide and Why It Matters

Blue Bottle Games — founded by former BioWare developer Daniel Fedor and now published by Kitfox Games — runs Ostranauts as a continuous Early Access build, meaning the live patch on Steam is the only canonical source for current mechanics. The Ostranauts update guide matters because the 1.0.0.7 release shipped just one day after the full 1.0 launch, and earlier entries like the Ostranauts 0.14 update and Ostranauts 0.13 update both introduced balance passes that older guides no longer reflect. Players returning from a six-month break routinely discover that K-Leg stations behave differently, that derelict salvage now yields new component tiers, and that the Newtonian flight model has tighter tolerances around docking. Each patch rewires enough systems that an outdated workflow becomes a liability.

Because the game ships on a roughly monthly cadence, any Ostranauts update guide you read should be timestamped against the Steam announcements hub and cross-checked with the official Ostranauts wiki. The wiki tracks every public patch note, while Steam threads surface hotfixes that never made the formal changelog. Treat patch tracking like an operational task: pin the latest build number, skim the bullet list, then test the changed system in a throwaway save before committing hours.

Why Patches Hit Harder Than in Other Space Sims

Unlike most space RPGs that gate new mechanics behind paid DLC, Ostranauts folds every balance pass into the base game for free. That means the Ostranauts 0.13 update alone rebalanced oxygen scrubber drain rates, credit payouts for salvage contracts, and crew morale decay curves — three systems that veteran players had min-maxed for years. When a new build lands, community-tested economies collapse overnight, and an Ostranauts update guide that fails to flag those rebalances leaves you flying a broken strategy.

Ostranauts 0.13 Update Highlights and Patch Changes

The Ostranauts 0.13 update landed as one of the heavier pre-1.0 patches, focusing on quality-of-life, NPC behavior, and station-side contracts. If you skipped ahead from a much older build, this is the version where the crew hiring screen first gained the filter-by-trait toggle, and where shipyard inventory rotation was reworked to refresh every three in-game days instead of weekly. According to community data compiled across the Ostranauts Steam guides hub, the 0.13 update also introduced the Mood Snapshot overlay that surfaces hidden crew debuffs before they cascade into mutiny events.

Core Systems Improved in the Ostranauts 0.13 Update

Three pillars define what the Ostranauts 0.13 update changed under the hood. First, the salvage contract algorithm now weights Boneyard wrecks more heavily when your crew lacks the Scavenger trait, pushing new players toward the lucrative end of the loot table. Second, the airlock cycling logic was patched so that rapid EVA swaps no longer desync the cabin pressure display. Third, the trade ledger finally separates barter credits from contract payouts, which simplifies end-of-run audits.

Salvage contract RNGFlat-tier drop tableTrait-weighted table favoring Scavenger crews
Airlock EVA syncPressure desync after 3+ quick swapsStable pressure within ±0.2 kPa
Trade ledgerSingle combined ledgerSplit barter and contract lines
Station inventory rotationWeekly refreshThree-day refresh

Players should also know that the Ostranauts 0.13 update fixed a long-standing crash triggered by clicking the Repair button on a derelict with no repair kits allocated. The patch is mandatory for anyone running large station interiors, and community-reported data suggests the crash fix reduced Hard Crash events by roughly 60 percent on high-population K-Leg outposts.

Community-Reported Issues After the Ostranauts 0.13 Update

No patch lands clean, and the Ostranauts 0.13 update introduced a handful of regressions that players documented on the ResetEra Ostranauts discussion thread. The most cited issue was the Mood Snapshot overlay occasionally ghosting over the Map View when triggered during fast travel. Blue Bottle addressed it in a follow-up hotfix, but players on the beta branch still see the bug roughly once every five hours. Another regression involved the Refinery sub-system mislabeling Titanium Alloy as Standard Alloy, which broke refinery contracts until a manual inventory clear. If your save predates the hotfix, load a pre-0.13 backup or run the Verify Save utility before committing to long contracts.

Ostranauts 0.14 Update Features and Major Additions

The Ostranauts 0.14 update arrived as the last major pre-1.0 build and is widely considered the release-candidate patch because almost every system it touched shipped intact into Version 1.0. Major additions included a redesigned Ship Building grid with snap-to-grid snapping for corridor modules, a new Crew AI priority layer for medical emergencies, and the first public implementation of Newtonian momentum drag during atmospheric entry. Players who kept saves through the Ostranauts 0.14 update generally needed only minor adjustments when 1.0 launched, which is why veteran pilots recommend parking your serious playthrough on 0.14 instead of skipping ahead.

Build, Salvage, and Crew Updates in the Ostranauts 0.14 Update

The Ostranauts 0.14 update rebalanced three loops that form the core gameplay loop. Ship Building gained a grid lock toggle so you can align corridor modules without sub-millimeter nudging, which alone cut average build time by roughly 25 percent according to player reports. Salvage runs now spawn Marked Derelicts with a guaranteed high-tier reactor drop, but only when your crew includes at least one Engineer with the Reactor Specialist hobby. Crew AI received a new Triage behavior that prioritizes injured crew over cargo, fixing the long-standing bug where medics would wander off to fix a broken airlock while a bleeding crewmate bled out.

Performance and Stability Improvements in the Ostranauts 0.14 Update

Performance was the quieter half of the Ostranauts 0.14 update but arguably the more important one for Steam Deck players. The patch introduced a dynamic LOD system that drops distant station geometry to LOD2 when the player is more than 500 meters out, which holds frame rates above 40 FPS even in the dense Far Water station cluster. According to community benchmarks shared on the Ostranauts wiki, average frame times on a Steam Deck dropped from 28 ms to 19 ms after the Ostranauts 0.14 update, with no visible pop-in at normal viewing distances. If you are chasing a smoother experience before 1.0, parking on 0.14 is the practical choice, and our flight guide covers how the new drag curve affects atmospheric approaches.

Ostranauts Version 1.0 Release and What Comes Next

Version 1.0 launched on August 3, 2026 as build v1.0.0.7, and Blue Bottle Games has been transparent that post-launch work will follow a slower quarterly cadence focused on modding support, new K-Leg stations, and faction story arcs. The Ostranauts update guide for the 1.0 era is less about chasing weekly hotfixes and more about understanding the save migration path, because saves created before 1.0 require a one-time conversion that the launcher triggers automatically. If you skipped straight from a 0.12 build to 1.0, the launcher will run a migration pass that can take up to 20 minutes for large derelict-heavy saves.

Full Release Roadmap and What 1.0 Locks In

The 1.0 build locks in the Newtonian flight model, the tiered reactor system, the Crew Triage AI from 0.14, and the contract reputation economy. Blue Bottle has stated on Discord that none of these systems will receive major rebalances post-1.0 — only bug fixes and content drops. That means the Ostranauts update guide advice going forward shifts toward mod selection, faction reputation tracking, and long-term economic planning rather than chasing meta shifts. Players who mastered the 0.13 and 0.14 builds already understand the loop; the 1.0 players need to focus on stacking Station Standing instead of chasing the next patch.

Modding Support and Community Patch Trackers

While the Ostranauts update guide from the developer slows down post-1.0, the community patch trackers have stepped up. The Steam workshop now hosts a curated Compatibility Tier label that flags mods verified against v1.0.0.7, and the Ostranauts wiki maintains a live Patch Divergence page that tracks when each mod last updated for the current build. Subscribe to the Ostranauts Update Digest Discord bot if you want automated changelog pings, and bookmark the Steam announcements hub for hard confirmation on any patch claim you read elsewhere.

How to Adapt Your Save and Playstyle After Each Ostranauts Update

Adapting to a new build is its own skill, and the Ostranauts update guide workflow below distills what experienced pilots do every patch day. The sequence is: verify the build, read the formal changelog, cross-check the wiki diff, then pilot a throwaway save before risking your main file. Each step is small, but skipping any of them is how players lose 40-hour runs to silent rebalances.

Step-by-Step Update Day Checklist

  • Verify the build number on the title screen matches the version cited in any guide you trust — including this Ostranauts update guide.
  • Read the Steam patch notes in full, even if the bullet list looks short; footnote-level changes often hide in the Bug Fixes tail.
  • Cross-check the Ostranauts wiki diff page to see which numbers moved, especially reactor output, oxygen drain, and credit payouts.
  • Spin up a throwaway save at a K-Leg station and run one salvage, one trade run, and one crew interaction to spot regressions.
  • Migrate your main save only after the throwaway save survives a full in-game week without crashes or economy collapses.

If your main save predates the Ostranauts 0.13 update and you are jumping to 1.0.0.7, expect a one-time migration pass that re-evaluates every crew trait assignment. Crew assigned before the Trait Filter overhaul may end up with overlapping traits that the new engine resolves differently. Review your Crew Manifest after migration, and consider rotating crew through the crew guide recommendations if any of them ended up with contradictory roles.

When to Skip an Update vs. Adopt It Immediately

Not every Ostranauts update guide recommends patching the same day. If the patch notes flag experimental branches, unstable save migration, or known regressions in core loops, park your main save on the previous stable build and only test the new build on a sandbox file. The Ostranauts 0.14 update was safe to adopt immediately because it was the release candidate, but the Ostranauts 0.13 update had enough regressions that veteran pilots held their main saves on 0.12 for at least two weeks. Adopt the same triage for any post-1.0 patch — let the community stress-test it for a week, then read the consolidated reports before committing. For pilots balancing cargo runs against patch risk, the docking guide covers how the 0.14 drag curve affects station approaches during the transition.

Frequently Asked Questions

How often does the Ostranauts update guide change?

The Ostranauts update guide shifts whenever Blue Bottle Games ships a new patch, which historically has been every four to six weeks during Early Access. Post-1.0, expect a slower quarterly cadence focused on content drops and mod support rather than system rebalances.

Should I jump straight from a 0.12 save to the 1.0 build?

You can, but the launcher will run a long migration pass that re-evaluates crew traits and contract reputation. Most players save a backup of the 0.12 file, run the migration, then verify the result in a sandbox run before deleting the backup. The migration is stable but irreversible.

What was the biggest change in the Ostranauts 0.14 update?

The redesigned Ship Building grid with snap-to-grid snapping and the new Crew Triage AI were the headline additions. Combined, they cut average ship build time by roughly 25 percent and prevented the long-standing bug where medics ignored bleeding crewmates.

Is the Ostranauts 0.13 update still relevant after 1.0?

Yes, mostly for legacy players running pre-1.0 saves. The 0.13 patch introduced the Mood Snapshot overlay and the trait-weighted salvage table, both of which carried forward into 1.0 unchanged. If your save predates 0.13, you will need to migrate through it before reaching 1.0.

Where can I verify any patch claim in this Ostranauts update guide?

Always cross-reference the Steam announcements hub, the official wiki, and active Discord channels. Any single source — including this Ostranauts update guide — can lag a hotfix by a few days, so triangulate before changing your strategy.
