   [fixed](https://github.com/lightningnetwork/lnd/pull/9572), the affected RPCs
   are `SubscribeChannelGraph`, `GetChanInfo`, `GetNodeInfo` and `DescribeGraph`.
 
-* [Fix a bug](https://github.com/lightningnetwork/lnd/pull/10064) where the
-  `GetChanInfo` was not returning the correct gRPC status code in the cases 
-  where the channel is unknown to the node. The same is done for `LookupInvoice`
-  for the case where the DB is kvdb backed and no invoices have yet been added
-  to the database.
 
 ## lncli Updates
-* Previously, users could only specify one `outgoing_chan_id` when calling the 
-  `lncli queryroutes` or the QueryRoutes RPC. With this change, multiple 
-  `outgoing_chan_id` can be passed during the call.
