Aquarium 2014 Update 26 December 2013

To all ChessOK Aquarium 2014, Houdini 4 Aquarium and Houdini 4 PRO Aquarium users: an update for all products using the Aquarium 2014 interface has been released. New customers buying the download versions of these products do not need this update as it is already included.

The update adds an option to import IDeA projects and trees from the old format (.hsh) to the new one (.aqt). Fixes a number of critical bugs. Updating is strongly recommended.

To update your Aquarium software, download the file for your version (64-bit or 32-bit) from the Updates and Patches section and run it, then follow the instructions.
