+Fee filtering of invs (BIP 133)
+------------------------------------
+
+The optional new p2p message "feefilter" is implemented and the protocol
+version is bumped to 70013. Upon receiving a feefilter message from a peer,
+a node will not send invs for any transactions which do not meet the filter
+feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki)
