Enigma 1.6.0 has just been released.

From the release notes:

• Thanks to another great user suggestion, I have added another hint - "Unused Letters". This hint will show you a list of the letters that you have not yet used in the puzzle solution.
• Also in response to several users requests, I have modified the program so that it keeps track of all of the puzzles that you've played. It won't repeat any of them until you have finished them all. Then it will start over again.
• Implemented some run-time improvements with more to come in future updates. You may not notice these much (for example, the opening screen with the random letters now draws much faster) but the more of these we implement, the more your battery will thank us.

Make sure you get the update and enjoy!
