We have been considering to change the FiveWin version number using the same way as Ubuntu Linux does:
The year and the month, i.e.: next build will be 6.12 meaning that is released on 2006 December. i.e.: Next year, February: 7.02
This way we don't have to ask users about the dates of the libraries that they are using. The FW/FWH/FWPPC version number will mean year and month.
We believe this is a very good idea in order to provide a better tech support. We appreciate your comments, thanks!
