+# Hush 3.10.5 ""
+
+  * Concurrent `z_sendmany` now works
+    * A longstanding bug relating to run multiple `z_sendmany` operations at
+      once has been fixed. You can now queue up many `z_sendmany` operations
+      and they will succeed because they now understand how to avoid spending
+      coins that another `z_sendmany` process is trying to spend.
+  * New RPC `z_listlockunspent`
+    * Lists shielded notes (coins inside a zaddr) which are temporarily unspendable because an RPC process is currently trying to spend them.
+    * If that operation succeeds, they will become spent. If it fails they will be unlocked and become spendable again.
+  * Fixed DragonX checkpoints
+    * Hush checkpoints were mistakenly listed as checkpoints in the 3.10.4
+     release, which caused some nodes to be unable to sync.
+    * This release fixes this issue.
+  * Updated test framework and tests which allowed the fixing of the `z_sendmany` bug above
