0.20.0 Jun 3, 2020 New Release Removal of BIP61 reject network messages from Bitcoin Core
The -enablebip61 command line option to enable BIP61 has been removed. (#17004)
This feature has been disabled by default since Bitcoin Core version 0.18.0. Nodes on the network can not generally be trusted to send valid messages (including reject messages), so this should only ever be used when connected to a trusted node. Please use the alternatives recommended below if you rely on this removed feature:
Wallets should not assume a transaction has propagated to the network just because there are no reject messages. Instead, listen for the transaction to be announced by other peers on the network. Wallets should not assume a lack of reject messages means a transaction pays an appropriate fee. Instead, set fees using fee estimation and use replace-by-fee to increase a transaction’s fee if it hasn’t confirmed within the desired amount of time.
