This release has two parts 1) Bug fix. we had the letter 'u' or F5 used as a hot key to update the grid. The letter 'u' was being blocked when entering text. we removed 'u'. the only hot key now is F5. 2) Added 3 or 4 more timing files into the songs directory. There is a new file README.songs that will eventually have the links of where to buy the songs that match the timing files.
