Direct Post Method and SHA-512 upgrade

Does anyone know if the x_fp_hash field sent to authorize.net in a POST will need to be updated to use SHA-512 with this upgrade? I understand the response back from authorize.net will now have have an x_SHA2_Hash field  but wasn't sure about what I needed to send them initially.

I will add, however, that the recent announcement that went out regarding the impending drop-dead for the MD5 hash specifically mentions it no longer being included in the transaction response. It does not specify whether support for it will also be dropped simultaneously in transaction requests (x_fp_hash). Maybe someone from Authorize.net can chime in on this to clarify if both will happen at the same time.
