MATLAB: Does the prerequisite list of products for Target Support Package 4.0 (R2009b) not match the prerequisite list for previous releases

Target Support Package

The prerequisite list for the product Target Support Package TC2 3.2 (R2009a) has products like Simulink Fixed Point, however some of these products are not in the prerequisite list for the product Target Support Package 4.0(R2009b).
If I buy Target Support Package 4.0 and later want to use Target Support Package TC2 3.2, I will be unable to use Target Support Package for R2009a. This is because I may not have purchased Simulink Fixed Point while placing the order for Target Support Package for R2010a.

As of R2009b, the products Target Support Package FM5, Target Support Package TC1, Target Support Package TC2 and Target Support Package TC6 have been merged into a new product, namely, Target Support Package.
The prerequisite products for Target Support Package are different from the individual products used earlier. If you want to use these individual products in the earlier releases, for example, Target Support Package TC2 3.2 in R2009a, you would need to have Simulink Fixed Point installed.
