4.6C and ECC 5.0 change information

Hi All,

I want to know where to find the documentation of ABAP related changes between two versions .( Specifically between 4.6c and ECC 5.0 )

By ABAP changes, I mean if any extra functionality is added to the ABAP objects in the newer version or the reverse.

I searched the help files, I found only the functional changes various module wise. (The delta documentation for two versions ).

Can I find the same for ABAP objects?

Regs,

Ags.
