Alpha 4 has been hotfixed to Alpha4e. If you want to update, you can re-use your existing download link. It never changes and always has the latest version.

If you’re not sure about your version, open Version.txt in the RimWorld folder. The latest is 0.4.462 rev40### (where # can be anything).

Alpha4b added the source code which is supposed to be included.

Alpha4c fixed the storytellers, who had a bug that made them permanently placid instead of ramping up over long games. Now they will ramp up properly and eventually, probably, kill you. But hey, it’s all about the drama!

Alpha4d lengthened the ramp-up time for challenge. It also adds a “need sawmill” alert to reduce confusion around the wood planks system.

Alpha4e rebalanced the storytellers again in light of this poll.

Sorry for all the hotfixes. Testing storytellers properly is really hard. We’re working on some automated metrics so balancing won’t be such a scattershot process in the future.

Your savegames from all Alpha 4 versions will still work.
