The current official version of Tidalis is still 1.000. These later beta versions are previews of content-to-come, and will later be "officially" released via Steam, Impulse, etc, once our vetting process is over with the new changes and features.
Full release notes:
http://arcengames.com/mediawiki/index.php?title=Tidalis_-_1.001_Beta_ReleaseThe official release of Tidalis has come and gone, and the game has now been officially in the hands of players and reviews for a week now. Overall things are looking great, but there are a few things that players have found or have suggested that we wanted to take care of. This beta update marks the first steps toward our first free DLC update for Tidalis (which will also include fixes for the various post-release reported bugs, most of which are thankfully pretty minor). The official release of this DLC update is expected to be sometime this week or next week, but for now this is the first of at least two or three beta updates to come out in the meantime.
IMPORTANT - Direct Download LinksUnfortunately, after the 1.001 version was released it was discovered that the 1.000 version of the game has a broken download mechanism for its installer. We ran into this one other time, all the way back at 0.401, so fortunately we have a simple mechanism for dealing with that. If you simply download and run the manual patch program below for your operating system (Windows or Mac), then you'll be all set and future automatic updates should work just fine.

Windows 1.001 Patch*
Mac OSX 1.001 PatchWe apologize for the inconvenience of this -- the 1.000 version fixed a problem with the Mac version of the updater, and unintentionally introduced this larger problem to both the Windows and Mac versions of the game.
