::Update::We are seeing more and more adaptation of the new client. This is good news for the network.
We are nearly certain there is a fork, which is being held alive by 0.10.4.x clients. I would encourage everyone to upgrade now, and definitely before sending coins. Almost all 0.10.4.x client are reporting a block height much below the current height.
We have at least two large pools mining auxpow, one is constant and the other periodically jumps in. This is also a good sign. I have been in contact with the pools that have made commitments, and at least two are still working on getting the client installed.
There is an issue which has come up with at least the linux headless client around initial syncing in that it will mysteriously die. We have found this most prevalent on nodes that are slim on RAM. Syncing via bootstrap (
bootstrap ) or adding in a swapfile so you have a total of 4 gigs of RAM+Swap seems to cure this. We are looking into it for a better solution.
EDIT: After the initial sync, the swap file can be turned off.
