Anyway, what the hay. I downloaded and ran 24.0 and set mempoolfullrbf=1 in my bitcoin.conf. This will solve woes with wallets which refuse to support the RBF feature.
I haven't upgraded yet, bet when I do I'll likely enable it as well. I don't really want my node to holding on to transactions which other nodes have already replaced. Although it could also go the other way, in which my node accepts a replacement transaction, but the original ends up getting mined. Could be a bit of a mess for a while.( And I see everybody is eager to tell this to achow101 
)
Lol. I'm pretty sure he's aware of 24.0 being released, considering he is one of the people who signs the checksum file with each release. )
