Following on my earlier message, I am happy to announce a new soft fork to be deployed using BIP 9 - Version bits.

Please review BIP 9 as it has been updated for information on how Version bits soft forks activate.

This deployment is being referred to as CSV (CheckSequenceVerify) and will activate the following 3 BIPS as consensus rules:
BIP 68 - Relative lock-time using consensus-enforced sequence numbers
BIP 112 - CHECKSEQUENCEVERIFY
BIP 113 - Median time-past as endpoint for lock-time calculations

These BIP's have been updated with the deployment information:
bit: 0
startTime: 1462060800 "May 1st, 2016"   (mainnet)
           1456790400 "March 1st, 2016" (testnet)
endTime:   1493596800 "May 1st, 2017"   (mainnet and testnet)


Bitcoin Core will release 0.11.3 and 0.12.1 software which implements these soft forks in the near future.


Thanks,
Alex
