encoding had previously been non-standard since Bitcoin Core 0.8.0
(February 2012).
* **Version 4** blocks will likely be introduced in the near-future as
specified in draft BIP62. Possible changes include:
* **Version 4** blocks will likely be introduced in the near future as
specified in BIP65. These blocks will support the new
`OP_CHECKLOCKTIMEVERIFY` opcode described in that BIP.
* Reject version 4 blocks that include any version 2 transactions
that don't adhere to any of the version 2 transaction rules.
These rules are not yet described in this documentation; see
BIP62 for details.
The mechanism used for the version 2, 3, and 4 upgrades is commonly
called IsSuperMajority() after the function added to Bitcoin Core to
manage those soft forking changes. See BIP34 for a full description of
this method.
* A soft fork rollout of version 4 blocks identical to the rollout
used for version 3 blocks (described briefly in BIP62 and in more
detail in BIP34).
As of this writing, a newer method called *version bits* is being designed
to manage future soft forking changes, although it's not known whether
version 4 will be the last soft fork to use the IsSuperMajority()
function. Draft BIP9 describes the version bits design as of this
writing, although it is still being actively edited and may
substantially change while in the draft state.
