I have two questions.
1 - Why someone with new v1.0 already on block 1917342 but all others nodes on old versions and block explorer
http://explore.grokonet.com/ only on block 1888070.
2 - Why last hard checkpoint in new version still from 2014 year?
1) The node on block 1917342 is from a test. It will be orphaned eventually.
2) There hasn't been a reason for more checkpoints. After the hard fork, we will implement checkpoints. That is already ready to go.
Less than 2000 blocks to go!
