BIP118 (SIGHASH_NOINPUT) vs. ANYPREVOUT
The differences between SIGHASH_NOINPUT (BIP 118) and SIGHASH_ANYPREVOUT (proposed update to BIP 118) were discussed at the Sydney Socratic Seminar in July 2020.

There is not a real conflict between the proposals apart from the
naming. The NOINPUT original proposal was we want to have this
functionality and we’ll do it when the next version of SegWit comes
along. The next version of SegWit is hopefully Taproot. The original
way it was proposed meant that eltoo would’ve had to have been a
CHECKMULTISIG script path rather than key aggregation Schnorr key path
potentially. It is not technically any worse than what the original
concept was by having to go through the script path. It is just the
next progression now that we have some idea what the next version of
SegWit should look like.
