Hi there!

RimWorld's 1.4 content update is now available! It adds cross-expansion integration with new Ideology precepts that link to Biotech, gene-modding and inheritance improvements, diplomatic reactions to pollution dumping, polux tree seeds, tribalwear for kids, and many other miscellaneous changes.

In a previous announcement, Ty covered the juicy details of this update. That same announcement has been shared below, as well as the changelog with our latest rounds of testing.

Thanks to everyone who helped us test this update. The community goes above and beyond with feedback and reports, and it genuinely helps us get these updates out so quickly. We've also tested the update for savegame and mod compatibility. If you’d like to help test our updates in the future, please join the official RimWorld Development Discord.
