Release timeline

How to read this list

• 0.70.1 is the newest version shown on the site and the one to use if you want the most current build.
• 0.70.0 is the main stable release of the 0.70 line; 0.70.1 comes after it as a follow-up.
• The release candidates and betas are pre-release builds for 0.70.0. They are listed for history and testing context, not as the recommended version now that 0.70.0 and 0.70.1 exist.
• Release notes are published for each version, so you can check what changed between builds before updating.

What CorsixTH is

CorsixTH re-implements the game engine of Theme Hospital and loads the original game's data files. Once most of the original engine has been re-implemented in open source code, the project is intended to serve as a base for extensions and improvements to the original game.

To play CorsixTH, you need either the demo or the full game of Theme Hospital — the full game is available for example at GOG.com.
