Kindle Touch 7 - Collections Manager

I have just bought a new Kindle Touch (to replace my Kindle Keyboard, half the screen went blank).

I don't seem to be able to find the correct Collections Manager, and supporting Jailbreak etc., for the firmware version 5.6.2.1 on this new Kindle Touch.

Is this because there isn't a version yet or have I just not found it?

Can anybody point me in the right direction please?http://s.mobileread.com/i/smiliesadd1/help.gif
