Version 2.0 was more flexible than version 1.0. It allowed the user to configure to data file to specify the maximum number of players scores to save. It also saves the data in a much smaller file (more efficient save format. (Unfortunately, this format is not compatible with the format for version 1.0, so data must be reentered from scratch.) Version 2.0 also had various extra features and options, too numerous to mention. Version 2.1 of Golfhandicapper corrects a bug in version 2.0. This bug caused the program to delete all players over 100 when you deleted any player using the "Delete player" option. Version 2.1 also gives you the option of aborting the emergency save of data if something goes wrong during a program run (in version 2.0, the emergency save of all data was manditory if there was a program crash). Version 2.1 also saves score data in an even more efficient format, allowing for smaller SCR files. Version 2.1 can still read the files created by version 2.0, so there is no need to reenter data. Version 2.2 improves the hardcopy printout to give more efficient use of paper (more data per page, less wasted paper). Version 2.3 removes a restriction on the values of golf scores to allow individual users to decide if they want such restrictions. It also improves hardcopy printout efficiency even more. Version 2.4 fixes a bug created by the printout improvement in 2.3. Version 2.5 fixes a bug that can cause the "Low score this season" to be attributed to the wrong player under a rare combination of circumstances. It also speeds up disk I/O and the player name sort. Version 3.0 provides players with the ability to change the course rating when they enter a score. This allows the players to play on different courses and create a cumulative handicap. Version 3.1 fixes a few bugs in version 3.0. Version 3.2 fixes a bug in version 3.1. Version 4.0 uses the slope method, to bring it into compliance with current USGA procedures. There is also a small change in the input fields, so that the program does not automatically go to the next field when a field is full (has had the maximum number of characters input). This solves the problem of people accidentally pressing ENTER on an empty field because the program went to that field automatically when the previous field was full. Note: Data files from previous versions of Golf Handicapper are NOT compatible with Golf Handicapper version 4.0. If you are upgrading from a previous version to version 4.0, you should print out a hard copy of all your data before installing version 4.0. You will then nbeed to type in all the previous data manually. Version 4.1 fixes a minor printout bug (spitting out empty pages between printed score reports on some printers). It also displays previous settings when changing some settings. Version 4.2 fixes bug in long form printout of player's scores that printed +###.# in front of player's index number.
