The most notable changes:
- bitcoind used to listen on

- New mempool policies has been implemented to patch some attack vectors for chains of unconfirmed transactions, especially in relation to lightning network channels and similar contracts.
- TRUC (Topologically Restricted Until Confirmation, BIP 431) can now be used with transaction version 3 (now considered standard) instead of RBF.
- Full RBF (Replace By Fee) is now enabled by default
- RHEL 8 and Ubuntu 18.04 are now unsupported due to minimum required glibc version bump.
