All versions 1.1x, 1.9x and 2.9x are unstable beta releases - use them for testing only, and never distribute a program that is packed with them!

The current stable release is 3.03, and the next stable release will be called version 4.00.

To repeat: There will be problems. There are known bugs. You have been warned.
