Previously 0 was explicit and 1 was original bitcoin format. This has been reversed such that the original bitcoin format is 0 and the new explicit format is 1.
This is by no means a necessary change, but it is a navel gazing fix that might as well be included since the format is changing anyway to allow compact explicit amounts.
Previously all outputs had a fixed size (33 byte) commitment field.
With this change, explicit / unblinded outputs are serialized to 9 bytes,
saving 24 bytes of transaction space per explicit output.
SequenceLocks functions are used to evaluate sequence lock times or heights per BIP 68.

These changes decode valid SIGHASH types on signatures in assembly (asm) representations of scriptSig scripts.
This squashed commit incorporates substantial helpful feedback from jtimon, laanwj, and sipa.
CTransAction::IsEquivalentTo was introduced in #5881.
This functionality is only useful to the wallet, and should never have
been added to the primitive transaction type.
Define CTransaction::IsEquivalentTo(const CTransaction& tx)
True if only scriptSigs are different. In other words, true if
the two transactions are malleability clones. In other words,
true if the two transactions have the same effect on the
outside universe.
In the wallet, only SyncMetaData for equivalent transactions.
