Two important pieces of information came out:
1. KYC mandatory for the NET -> NIMIQ conversion
2. Denomination: instead of 1 NET -> 0.1 NIMIQ it will be 1 NET -> 100 NIMIQ. Total supply will be 21 billion NIMIQ instead of 21 million.

Release of the mainnet is still pencilled in for Q1 2018. Before that, there will be another update to the testnet.
