OK, so it is showing prohashing as not having an updated client when I check the peers.
They did update the client, but due to a bug their client misbehaved. A fix is already provided to them and we think it should solve the issue.
For now only linux binaries (32 bit and 64 bit) are updated as this bugfix only affects pools and solo miners.
We will slowly update windows and mac binaries as well.
Sorry for the inconvenience.
