As promised the fork occurred on October 25th.

Users that have access to their private keys can claim BTG at supported services. If you had any amount of bitcoin in your wallet during the fork you now own the same amount in BTG.
Bitcoin Gold started trading today with a price of 500$ on some exchanges but quickly dropping below 200$ on most sites.
As mentioned in the Warning bitcoin.org released, mobile users should still avoid making transactions at the current time since this could cause double spends.
