and according to information i got, you should never expect core elements that were working on a version, to continue to work on the next version. when a release is brought to the public, not only should it portray what is new and flashy, but what was taken out?

yall remember 'chicks for free' v-6 (removed) later added in the market for purchase

yall remember recurring payments for memberships v-6 (removed) later added as a module in the market for purchase.

so never presume what worked see more in one version to work on the next version, not only when considering 3rd party modules, but also considering core elements.
