The following link shows the changes in I0coin 0.12.0 (which is based on Bitcoin 0.12.0).
https://bitcoin.org/en/release/v0.12.0There are no hard or soft forks between I0coin 0.11.9 and 0.12.0. So miners should be able to upgrade to 0.12.0 without issues.
This coin is so ready to rock and blast to my $10 target. This time for keeps.
When that happens don't forget who the King of Crypto is, niggaz!
