Developer toolbox and CS5.5

Hello,

I would like to upgrade from Adobe CS4 to 5.5. But I do have one concern. I am used to work with the Developer Toolbox and I am afraid it won't work anymore with CS5.5? Is there a possiblity to use it in CS5.5 or is there something similar in CS5.5? What is the solutione?

Thanks in advance.

Gr, Pien
