Youre right .
In 1.4.0 they did not only introduce Cut & Paste but also did an overall maintenance of all components .
For example : They revised the entire networking component .
If you are into P2P using JAVA that alone should urge you to upgrade .

Besides I don't know why all these people are making a fuss about it .
It's free ! You can download it freely .
They even changed the license agreement so you can burn it onto a CD and give it to your frends !
(Wich you already do but now it's really legal OK ?)
