+  serving v2 onion services in October 2021, and lnd no longer produces
+  v2 on any code path; `tor.OnionHostToFakeIP` is also gone. Operator

+  `.onion` string, so operators upgrading with a v2 entry in
+  `lnd.conf` must remove it before lnd will start. Persisted state
+  carried over from a previous version is also filtered before use:
+  the self-node announcement strips any v2 entry from the source-node
+  record before signing; the watchtower client drops v2 entries from
+  each persisted tower's address list (skipping the tower entirely if
+  no non-v2 address remains so the operator can attach a fresh v3
+  address); the autopilot, graph bootstrapper, and static-channel
+  backup restore paths skip v2 entries before attempting outbound
+  dials. The on-disk records are left intact.
+
+  Peer-signed announcements that still carry v2 are handled
+  byte-for-byte: the `lnwire` and `graph/db` codecs round-trip v2 so
+  `DataToSign` reproduces the signed bytes, signatures validate, and
+  the announcement is persisted and re-broadcast unchanged. RPCs like
+  `GetNodeInfo` and `DescribeGraph` still expose the full address
+  set.
