This option allows separating +transaction submission from the node functionality. + +Making use of this, third-party scripts can be written to take care of +transaction (re)broadcast: + +- Send the transaction as normal, either through RPC or the GUI +- Retrieve the transaction data through RPC using `gettransaction` (NOT + `getrawtransaction`).

The new option, +`-proxyrandomize`, is on by default. + +When enabled, every outgoing connection will (potentially) go through a +different exit node. That significantly reduces the chance to get unlucky and +pick a single exit node that is either malicious, or widely banned from the P2P +network. This improves connection reliability as well as privacy, especially +for the initial connections. + +**Important note:** If a non-Tor SOCKS5 proxy is configured that supports +authentication, but doesn't require it, this change may cause it to reject +connections. A user and password is sent where they weren't before. This setup +is exceedingly rare, but in this case `-proxyrandomize=0` can be passed to +disable the behavior. 0.11.0 Change log ================= Detailed release notes follow.
