The upgraded support is accompanied by a few other relevant tweaks.
In addition to introducing Cross Buy, Sony dropped some other relevant Vita information. Version 1.80 of the system firmware will bring with it support for PSone Classics. Though the feature was planned and announced before the release of the system, it wasn't ready for the release or in the months following. On August 28 that will change as the company begins incrementally rolling out full support for the hefty catalog.
