This works with wallet disabled. +New bytespersigop implementation +-------------------------------- + +The former implementation of the bytespersigop filter accidentally broke bare +multisig (which is meant to be controlled by the `permitbaremultisig` option), +since the consensus protocol always counts these older transaction forms as 20 +sigops for backwards compatibility. Simply fixing this bug by counting more +accurately would have reintroduced a vulnerability. It has therefore been +replaced with a new implementation that rather than filter such transactions, +instead treats them (for fee purposes only) as if they were in fact the size +of a transaction actually using all 20 sigops. + + Low-level P2P changes ---------------------- |
