Yes, 1..05! It was supposed to be 1.04, but due to some save game issues, the boys over at Gaslamp Games have released the new Dungeons of Dredmor patch through the Steam gaming network. Launch your Steam client for the automatic update.
This is a major patch that really brings about a ton of changes. So much so, that the Steam leaderboards are getting a reset along with the patch release. Congratulations to Gaslamp Games on a job well done!
