• Jigsawed now keeps track of your progress. Completed puzzles appear with green or yellow checkmarks in the image browsers depending upon whether you completed the puzzle alone or with help.
• You can now "Start Blind," and the puzzles will come pre-shuffled so that you don't know what the picture is like until you've completed it.
• You can now click "Random" to get a puzzle you haven't yet completed at random. Combine this with "Start Blind" for extra fun.
• Bug fixes.
• Loading saved puzzles is now 3-10x faster depending on the size of the puzzle.
• The puzzle dividing lines now fade out when the puzzle is complete so that you can get a better look at your accomplishment.
