EDIT: This was updated to 1.0.2282. It should now be compatible with pretty much everything except the ModCheck mod. Please let us know about any problems in the comments! Reading carefully.Original post below:On the unstable beta branch, you'll find version 1.0.2271. This version is almost the same as the previous version, with the following changes:

• A potential fix for a bug that can cause very slow loading of mods in some cases.
  
• Updated language data to latest version.
  
• Updated player-created names with all approved content.

Mostly we're looking to test the first of the above. It would be awesome if any player who had trouble with slow loading of mods (anything over a minute or two) would give the unstable branch a try and let us know if anything changes.Thanks in advance to anyone who can give feedback on this in the comments here or in the Ludeon forums[ludeon.com]!The new version should be compatible with all saves and mods, except possibly a few mods that directly interact with ho...

I’ve just released a technical update to version 1.0 of RimWorld. It should be 100% compatible with all existing savegames and mods. The new version is 1.0.2150.Steam will auto-update. If you’re playing the DRM-free version of the game you can go download it now from your permanent personal download link which was emailed to you.Aside from updating translations and player content, and fixing a handful critical bugs, the new version’s main purpose is to add support for multi-version mods. Previously one entry in Steam workshop could only work with one version of RimWorld. This causes problems when we release a new version: Players can’t continue on the old version since some mods are updated, but can’t continue on the new version since not all mods are updated.Now, mods will be able to support multiple versions simply by putting version-specific files in directories named for the target game version. Other files from the mod’s base directory are used in all versions, as before.For modde... Read more

Alpha 17 - On the Road has been released! This version brings roads and rivers to the world, new world quests, new tools for modders, new combat tools, smarter AI, and rebalancings and adjustments across the whole design.I'm afraid that this build is not compatible with saved games from previous versions, or mods from previous versions. However, you can continue to use the old version until you're ready to update. If you're on Steam, to continue using the old version, go to your Steam Library, right-click on RimWorld, click Properties. Open the Betas tab and use the drop-down menu to select the alpha16 version. Restart Steam to force an update.If you downloaded the game DRM-free, you can update whenever you like by re-downloading from your existing download link. Your link is always the same and always gives the latest version.In the old builds, balance problems meant that some exploit-y strategies did work and obviated some of the challenges in the game. Since those problems are now f... Read more

I’ve just released Alpha17b, a performance hotfix for Alpha17. Steam users will get it automatically. This is build 0.17.1557.When we made the targeting AI smarter in Alpha 17, we also made it harder on the CPU. Players in late game were seeing drastically reduced performance. Alpha17b optimizes this and several other things. There are no changes to gameplay - just optimization of what's there already.This update will work with your existing saved games, XML-only mods and (hopefully) most or all code mods.If for any reason you want to continue on the older version, you can set your Steam beta branch to 'alpha17a'.Sorry for any disruption! We’re also hard at work on Alpha 18. Read more

We'll be closing sales for to the Backstory-in-Game package and Pirate King packages on November 7, 2017. The Name-in-game package will remain on sale. Anyone who already purchased any of these packages won't be affected, only new sales will be closed.I'm closing these sales because the game is maturing and it's coming to the right time to make the content final. In addition, closing these will free up more time for us to work on the game itself.Thanks everyone for all the great content submitted over the last few years! As any player can tell you, it's really enriched the game. Read more

RimWorld Beta 18 - A World of Story is released! Here's the video (where I accidentally call it Alpha 18 - old habits die hard).https://www.youtube.com/watch?v=IPI2vUqdZFYTo get the update: If you're on Steam, the game will update automatically. If you're DRM-free, you can re-download from the same link you got the game from originally. It always has the latest version.It's finally in Beta! This is build 0.18.1722 of RimWorld. That last number is the number of days since I first started working on RimWorld in February 2012. 1722 days - almost five years. It's come a very long way since the first public look in September 2013. It's time to start bringing it to a close, which is why version 0.18 is Beta 18 instead of Alpha 18.The "Beta" designation means that we're on the final stretch before the 1.0 release, and that there won't be major content additions like whole new game systems. Of course we will almost certainly add more content, before the 1.0 release or after. We will also conti... Read more

RimWorld Beta 19 - Polish the Cannons is released!https://www.youtube.com/watch?v=FH5tLLJXbg8
If you want to keep playing Beta 18 on Steam: Right click RimWorld in the Library list -> Properties -> Betas -> Choose beta18 from the drop-down menu.You can play savegames from Beta 18 (and probably before), though some details will change upon loading.I did want this build to be 1.0 for a while, but it became apparent the game would benefit from one more refinement round, so we're doing Beta 19 first. I very much want the 1.0 version to be worthy of its version number, which means not rushing it.You can discuss this post in this forum thread on the Ludeon forums[ludeon.com] or in comments below.Below is a list of notable changes. If anything below seems to change game balance, you can bet that related variables were adjusted to maintain roughly the same challenge as before - I just don't write down every single change because otherwise this list would be way too long. This list also does not...

So, RimWorld's early access price has been $30 USD since we first started selling the game in 2013.Buying an early access game is risky compared to buying a finished game. Also, RimWorld's value in content (and the time players tend to play it) have gone up a lot since those early days. There's also the matter of simple financial inflation. Because of these factors, the final price will be higher than the early access price.The early access price will remain the same for the rest of the early access period - this change will only occur when 1.0 is released. And of course, anyone who bought during Early Access will get the final version for no additional cost.I wanted to let everyone know about this ahead of time so people have time to make an informed purchasing decision without surprises.As of now there's no announced release date for 1.0 yet - still working on filling in all those final details!Discussion on the Ludeon forums[ludeon.com].

A new build is up on the unstable branch.If you are playing with mods but were on the unstable branch from an earlier testing phase, change back to default branch now. The code for this update should be 99% mod-compatible, but the mods won't work until they're recompiled because the binary API for the translation system changed.The game content is exactly the same as Beta 19. There are some bugfixes, but the most important thing is the new localization system. It'll help translators more accurately translate the game into non-English languages, with issues like grammatical gender (e.g. le/la in French) respected and better automatic handling of grammar for a variety of languages.Below is a forum post from Piotr Walczak, who implemented the latest improvements, explaining what translators can do to take advantage of the new functionality.Forum post: New keyed translations format[ludeon.com]For anyone interested in helping translate, now would be a great time! The game content is stable,... Read more
