Lines 11 to 14 in cd982b6

	- Added the parameter `protocolVersion` to `Block<T>(long, long, BigInteger,
	Nonce, Address?, HashDigest<SHA256>?, DateTimeOffset,
	IEnumerable<Transaction<T>> transactions, HashDigest<SHA256>?,
	HashDigest<SHA256>?)` constructor. [[#1142], [#1147]]

libplanet/CHANGES.md

Lines 99 to 102 in cd982b6

	- Introduced the [protocol versioning scheme][#1142]. This purposes to change
	the protocol without breaking backward compatibility. Even the protocol
	is changed, the existing blocks made before the new protocol are guaranteed
	to behave as it had done. [[#1142], [#1147]]
