Release date on green for the April 2001 patch?

[LeninTheRed]

Hello all

This patch introduces a change to enchanting that makes enchanting metal for cultural armor viable by removing the blue diamond reagent requirement. Previously, this requirement meant it was so expensive to make the armor (up to 5k in diamonds alone PER PIECE!) that it never made sense to do so. After the change it is attainable by even moderately wealthy players.

Anyway, the march 2001 patch dropped last month which means the April 2001 should have dropped this month, but so far nothing. Does anyone know when the planned release for this is?
