CHANGELOGS

v1.0.14

v1.0.14 did an emergency hardfork style upgrade to update feemarket parameters, all the mainnet nodes need to update to v1.0.14 before block 11608760, otherwise you'll face app-hash mismatch error.
If you didn't update the binary in time and got the app-hash mismatch situation, you need to do a cronosd rollback first to recover, then start the node with new binary.
