+`NODE_BLOOM` node service bit
+------------------------------
+
+Support for the `NODE_BLOOM` service bit, as described in [`BIP
+111'](https://github.com/bitcoin/bips/blob/master/bip-0111.mediawiki), has been
+added to the P2P protocol code.
+
+BIP 111 defines a service bit to allow peers to advertise that they support
+bloom filters (such as used by SPV clients) explicitly. It also bumps the protocol
+version to allow peers to identify old nodes which allow bloom filtering of the
+connection despite lacking the new service bit.
+
+In this version, it only enforced for peer peers that send protocol versions
+`>=70011`. For the next major version it is planned that this restriction will be
+removed. It is recommended to update SPV clients to check for the `NODE_BLOOM`
+service bit for nodes that report versions newer than 70011.
