One of the largest differences between L^ATEX 2.09 and L^ATEX2_e is in the commands used to write packages and classes. In L^ATEX 2.09, there was very little support for writing |.sty| files, and so writers had to resort to using low-level commands.

L^ATEX2_e provides high-level commands for structuring packages. It is also much easier to build classes and packages on top of each other, for example writing a local technical report class based on |article|.
