not the case for upgraded OP_NOP opcodes.

15d9399521 CH07: tone down beyond-bitcoin applications 
Bitcoin can do things beyond money, but (as other text in the chapter
notes) this can be controversial.  Let's not oversell those other uses
here only to throw shade on them later.

ec534165ba CH07: Switch from M-of-N to K-of-N

7417842837 CH07: prefix opcodes with OP_ 
I think this helps distinguish between opcodes and data
variables/constants.

8cdac91f1a CH07: drop description of op_return limits 
I think this is an overabundance of detail (and I'm not sure it's
correct about a 40-byte release; I think that may have been changed in
the RC phase).

There has also been recent (March 2023) discussion about making this
limit arbitrarily high, so this is something that might become outdated
quickly.

a1d7bd1ecf CH07: drop ref to "programmable money" 
I think this could be confusing.  It's not so much that the money is
programmable---in Bitcoin, your money won't go out and take actions on
its own based on programming.  Instead, Bitcoin allows contracts to be
enforced by deterministic full nodes rather than a more arbitrary justice
system.

107e331b2f CH07: Statlessnes is per-tx not per-script 
Some of the information necessary to validate a transaction is contained
within the transaction executing the script, such as the data the
signature commits to plus its locktimes for OP_CLTV & OP_CSV.

Matches the style used in Bitcoin Core, which matches the style we use
for other terms in this book.

6c0368c5c6 CH07: s/BIP-xx/BIPxx/ 
This is my personal preference.  I think it's maximally concise and
reasonably clear.  It's also popular, which aids in searching.

22ddf6a202 CH07: replace terms locking/unlocking with sPK/sS/rS/wP/w 
Although I understand the desire to use more human-friendly terms than
scriptPubKey, scriptSig, redeemScript, witness program, and witness, I
think it makes things less clear, particularly when we switch from
legacy to legacy P2SH to segwit v0 to segwit v1.

An additional problem is that, with scriptSig no longer being executed
(and witnesses never being executed), it's not quite accurate to use the
phrase "unlocking script".

This commit replaces "locking script" and "unlocking script" with either
the specific data type or with non-specific phrasing.

56c701a6ad C_Txes: edits (nearly complete rewrite) 
This chapter, containing parts of previous chapters 6 and 7, is almost
entirely rewritten.

- Instead of introducing concepts in a somewhat arbitrary order, almost
  every section except the last three (coinbase txes, weight, and legacy
  serializitaion) follows the order of transaction fields as seen in
  a P2P serialized transaction.

- We leave details of scripts for the next chapter (authorization &
  authentication), signatures for the chapter after that, and fees and
  fee bumping for the chapter after that (reflecting the increased
  importance of fees).
