Deployment shall be controlled by hash-power supermajority vote (similar to the technique used in BIP34), but the earliest possible activation time is 2016-01-11 00:00:00 UTC.

Activation is achieved when 750 of 1,000 consecutive blocks in the best chain have a version number with bits 1,2,3 and 14 set (0x20000007 in hex). The activation time will be the timestamp of the 750'th block plus a two week (1,209,600 second) grace period to give any remaining miners or services time to upgrade to support larger blocks. If a supermajority is achieved more than two weeks before 2016-01-11 00:00:00 UTC, the activation time will be 2016-01-11 00:00:00 UTC.
Activation is achieved when 750 of 1,000 consecutive blocks in the best chain have a version number with the first, second, third, and thirtieth bits set (0x20000007 in hex). The activation time will be the timestamp of the 750'th block plus a two week (1,209,600 second) grace period to give any remaining miners or services time to upgrade to support larger blocks. If a supermajority is achieved more than two weeks before 2016-01-11 00:00:00 UTC, the activation time will be 2016-01-11 00:00:00 UTC.

Block version numbers are used only for activation; once activation is achieved, the maximum block size shall be as described in the specification section, regardless of the version number of the block.
