+What's New in 1.12.1
+--------------------
+
+The 1.12 {+driver-short+} release includes the following improvements and fixes:
+
+- The driver unpins connections when ending a session. This prevents connections
+  from leaking when a user runs a transaction while connected to a load balancer.
+
+- The driver does not throw a runtime error when you unmarshal an empty
+  ``bson.RawValue`` type with an invalid type or marshal a ``nil`` pointer of a ``ReadConcern`` instance.
+
+- Setting ``options.LogComponentAll`` as the log component correctly results in the publication of logs against all components.
+
