I can confirm that
public static int[] getVersion()
will be available in edtFTPj 1.4.0 (the next release)
and also in edtFTPj/SSL 1.1.0 (next release, due out next week.
The array returned is {major, middle, minor} version numbers.
No, but it would be very useful. I'll request that this feature be added - e.g. a method such as getVersion(). We'll try to get this added to 1.1.0 which is due out soon - if you have bought 1.0.x when you see the announcement ask for a free upgrade.
