Most Plane of Knowledge vendors will have returned with today's patch.
The vendors that had mass-item inventories added to them last month have kept those inventories (except for those cases where Smithing and Tailoring supplies were erringly added to non-Smithing/non-Tailoring vendors). The inventories of the returning vendors are the same as they were prior to the February patch, so nothing new there other than their return to the zone.
Database listings have been brought up to date with what is seen in game. If you spot any discrepancies, please let us know.
