Hello everyone!

We've got a late-Friday patch to address a number of issues that came up in the Breath of Fresh Air Update.

This patch should address many of the immediate issues, especially concerning rocketry and UI.

Unfortunately, it seems that we didn't catch as many of these issues in the Public Testing branch as we had hoped. We have this patch for you today, and we are still going through your bug reports and feedback while we work to address your concerns, so please let us know any issues you're running into in the bug forums!

Additionally, there are some known changes which are going to take longer to work through, so we're putting up a temporary archive branch on steam which represents the state of the game prior to the Breath of Fresh Air Update. You can use this to continue existing saves or play on an older version while we work out the remaining problems. To play this version, right-click on Oxygen Not Included in your Steam library, click on Properties, and choose Betas > public_previous_version. (You may need to relaunch the Steam client for this option to appear.)

We know this update has not been great for many of you, and we're sorry for the frustration this situation has caused you! We will keep working hard to fix this situation, and to make ONI even better than it was before.

Thanks, as always, for being part of ONI's development with us! Have a great weekend.

Hey space friends!

It's been a while since we've done a big update to the base game of Oxygen Not Included! While we've been working primarily on Spaced Out! for the last while, our desire has always been to improve and evolve the game as a whole. There are a number of changes we've made in Spaced Out! which are just general good improvements to the game, or that we had planned for the base game all along but finally got the opportunity to implement during Spaced Out! development.

This includes bug fixes to the game and the underlying simulation, making improvements and upgrades to the UI, and a major upgrade to the modding system to help future-proof mod development. It also includes a couple new buildings, Duplicant traits, and improved worldgen.

Up until this point, the base game and Spaced Out! were running on separate codebases, so fixes we made would only exist for one version or the other. After today, the codebases have been unified so everyone is running the same version of the game! This has been an epic process for the development team, but now it means that bug fixes will arrive for everyone at once, and that all players can benefit from ongoing improvements to the game.

This patch includes some major code updates, including a new Modding API and an upgraded version of the Unity engine. There will be growing pains in the short term while mods are updated (please give modders a chance to catch up!) but these will support the stability and growth of the game into the future.

These changes address some long-term concerns in Oxygen Not Included. This game, and you the players, continue to inspire us. We want to keep improving it and making it the best game we can! The major features and changes include:

• New traits, including traits that grant skills to Duplicants right out of the printing pod
  
• Some shuffling of the tech tree, notably moving most of the Conveyor Rails techs one tier earlier
  
• Updated food storage mechanics, making refrigeration easier and more effective, but removing exploits and creating a natural progression for fully preserving food
  
• Meter Valves allow sending precise amounts of material down a pipe, manually or using automation
  
• Oxygen Masks are a new low-tier suit, allow Duplicants to work for longer in low-oxygen areas but not protecting them from harsh environments
  
• Suit durability mechanics will be available in the base game (off by default), which add some upkeep costs for suits so they aren't so overpowered
  
• "Stinging eyes" and related debuffs give more reason to be cautious with chlorine and other gasses and liquids
  
• The Diagnostics panel, updated Resource screen, and other UI improvements make it easier to stay on top of what's happening in the base
  
• Demolition skill allows duplicants to destroy those Gravitas ruins once and for all

There may be some inconsistencies as a result of this, so if anything has broken, or any Spaced Out! weirdness snuck into the base game, please report it in the bug forums. Thanks!
As the Spaced Out! DLC gets closer to launching, we're continuing to focus on polish, bug fixes, and tying up loose ends.

We're continuing to refine worldgen tuning, and have added a "Classic Forest Start" cluster to play on. Renewable regolith has landed back in the game on its own planetoid. There's lots of finalized animation and sound effects coming down the pipe, including new art and leak mechanics for nuclear waste barrels. We're also spending more time looking at performance and have some promising leads.

Colony Imperatives are being added and revised. With new Monument parts, an Artifact Analysis Station, and a strange Gravitas device hanging out near the Temporal Tear, your Duplicants will have so many boxes to check off! (We also added a few new Spaced Out!-exclusive artifacts.)

Thanks for sticking with us through this large technical challenge. If you notice anything that seems to be amiss between the two versions of the game, please report it as a bug! And as always, we'd love to hear any other feedback you have. Take care!

Hi friends,

Just a small patch today to fix a crash some OSX players are experiencing. Currently Apple Silicon/M1 is only supported through Rosetta and we accidentally included a non-functioning native build.

Fixes:

• Removed unsupported OSX arm64 binary (Apple Silicon / M1 chip)

Hello friends,

Today's release hotfix is quite small, but fixes a crash and a major issue with mod/save loading. Take care this weekend!

Bug Fixes

• Oxygen Masks no longer crash in Base Game
  
• Version numbers for Spaced Out! have been increased. The previous version numbers were causing incorrect versions of mods to be loaded. (SO! compatible mods will need their version updated to 469369 to fully resolve the issue.)
  
• The public_testing branch is being updated with the latest changes as well.

Hello friends!

Today we present The Big Merge Update: A highly technical squishing of the Base Game and Spaced Out! codebases. This means that Spaced Out! owners can toggle the DLC on-and-off from the main menu with a simple restart of the game. Playing the Base Game in this way will give you all the bug fixes and quality improvements that we've added to Spaced Out! since we went into early access, while still allowing you to enjoy the game-play of the original ONI you know and love.

(These changes will be coming to the Base Game for all ONI players in the next few updates, but we're limiting them to Spaced Out! owners to make sure they get proper testing for now.)

What we're working on here is the continuing evolution of Oxygen Not Included. While our attention has been mostly on the DLC lately, our desire has always been to improve and evolve the game as a whole. There are a number of changes that we've made in Spaced Out! which are just intrinsically good improvements to the game, some we had planned for the Base Game all along but finally got the opportunity to implement during Spaced Out! development.

This includes the many bug fixes and minor improvements we've made during Spaced Out's development, including fixing several major simulation bugs and countless typos. It also means modding should be simplified because there is only one version of the game to mod against.

Speaking of modding... We have a doozy of a modding update! Modders, please read Updating to Harmony 2.0. To all players: these significant technical changes are going to result in many mods needing updating in order to work. Please be kind to the modding community and give them time to react to the new code.

This patch also includes updating our development to the next major version of the Unity engine. While this has little impact on what you see as a player, it's necessary for us to continue supporting the game and pushing development forward.

These are the features that you've seen in Spaced Out! which are now going to be part of the Base Game:

• New traits, including skill-granting traits
  
• Some shuffling of the tech tree, notably moving most of the Conveyor Rails techs one tier earlier
  
• Updated food storage/refrigeration mechanics will be the same in both versions of the game
  
• Meter Valves are now in the Base Game
  
• Oxygen Masks are now in the Base Game
  
• Suit durability mechanics will be available in the Base Game (but toggled off in the game settings by default)
  
• "Stinging eyes" and related debuffs which give all players more reason to be cautious with chlorine
  
• The Diagnostics panel, updated Resource screen, and other UI improvements will be consistent for all versions of the game
  
• Demolition skill will be available for everyone!
  
• All other new content (in particular the new rockets and multi-asteroid starmap, and radiation buildings and overlay) will remain in Spaced Out! only.

Spaced Out! owners are now able to try this new version of the Base Game - just launch the game as usual and use the button in the main menu to toggle the DLC off. (You'll know it worked if your build number starts with "MD")

Thanks for sticking with us through this large technical challenge. If you notice anything that seems to be amiss between the two versions of the game, please report it as a bug! And as always, we'd love to hear any other feedback you have. Take care!

Hello modders!

Over the course of this last year, many in this community have requested that we update the version of Harmony that we ship with the game, in order to smooth out mod development and make sure modders have access to the latest features the Harmony API provides!

In the testing period beginning June 10th, we will be shipping Harmony 2.0.4.0 on the Public Testing branch.

This upgrade will require modders to update all .dll mods!

It is also the case that the major code changes we're doing right now are going to break a significant number of mods, and later when the Vanilla and DLC codebases are finally fully merged, all the existing Vanilla .dll mods will have broken anyways. We'd rather not break any mods at all, but since it's going to happen, we're opting to put all the breakage into a single update, and this gives you some time to prepare.


As we unify the codebases, all these changes (including the Harmony 2.0 update) will slowly roll down through various versions of the game, like this:

Spaced Out Public Testing -> Spaced Out (all players) -> Oxygen Not Included Public Testing -> Oxygen Not Included (all players)

So mods running on Spaced Out will have to be updated first, and will have this testing period to get updated before all Spaced Out players see the code changes.

The changes to the base game will happen some time after that, though specific dates are still being determined.

Once your mod has been made compatible, it will remain compatible for the rest of the Mergedown. (Breakage from normal ongoing development aside ;) ) Be sure to use mod_info.yaml and the archive folder to separate the versions of your mod and make the transition seamless for your users! (More details below)


There are three key changes you'll need to make:

1. Change all using Harmony; to using HarmonyLib; in your code
   
2. If you use OnLoad(HarmonyInstance harmony), change it to OnLoad(Harmony harmony)
   
3. Install the .net 4.8 developer pack, and retarget your project at .net 4.8.

Additionally:

• A number of methods in Harmony have changed signature or scope, so various compile errors will have to be resolved
  
• As always, a number of changes have happened in the ONI code, so those errors will have to be resolved
  
• Update your mod_info.yaml as described below for best compatibility. NOTE! If you're currently using a single version of your mod that runs on Vanilla and Expansion1, you will likely want to two versions of the mod for the duration of this Harmony 2.0 rollout.
  
• Finally, upload the new version of your mod!

Here's the official Harmony update information.
Here's the full list of patch notes (Reminder, we're on 2.0.4.0, catching up from 1.2.0.1).
The full Harmony 2.0 documentation.

Please let me know if there are any gotchas or missing steps I should include in this post!

A huge thanks to everyone in this community! I know from personal experience how much work it is to keep modding a game that is in active development, but the champions here nonetheless have made a workshop full of amazing mods! It's always exciting to browse through and see what's new, and to get the chance to play visions of the game that are different than our own. How cool is it that these things can co-exist side-by-side? So again, THANK-YOU!

mod_info.yaml for Hamony changes can be found on the post on our official forums here.

Hello everyone! Today's Spaced Out patch includes a few fixes, including a crash on the Diagnostics screen that people were running into. Have a great week!

• Fixed issue where old saves would not have Space POIs added until unpaused.
  
• Refreshed "Mine The Gap" update name in main menu image header.
  
• Fixed bug where "Satellite Asteroid Field" space Point of Interest had invisible art.
  
• Fixed crash caused by searching diagnostic screen while looking at a rocket interior world.
  
• Updated Korean translations.

Hi friends!

Welcome to the Mine The Gap Update for Spaced Out! This update brings increased resource renewability with the introduction of Space Points-Of-Interest! Equip a rocket with the new Drillcone and start dredging those interplanetary riches!

While you're out there, keep your eyes open for artifacts! Yes, Gravitas artifacts are back! Collect them all from a number of new and updated points-of-interest. Once you're done gathering them, you can teach your Duplicants the "Demolition" Skill and wipe those Gravitas buildings off the map if you feel so inclined. (World regen is required for the new points-of-interest to show up.)

We've also done some significant rebalancing of the tech tree as we work to optimally integrate new mechanics into existing gameplay. The Atomic Collider and Atomic Research Points are being redesigned as the Materials Study Terminal and Materials Science Research so they’re more thematically neutral for application across the tech tree. Techs have been shifted around and costs have been standardized (including moving all Orbital Research costs up one tier) to reduce the burden on unlocking tier 5 techs.

Plus, we've made changes to the Radbolt Generators and adjusted the overall radiation balance. There is now increased control over Diagnostics criteria on the Diagnostics screen. Biome Codex entries have been finished up. And, some exciting new changes to bottled gasses and liquids: they can now liquify/solidify if they get cold enough!

This update provides new sources of sustainability and a whole new layer of gameplay on the starmap. We welcome your feedback and bug reports! Once again, thanks so much for being with us through this DLC's Early Access period.
