+## 1.2.2 (November 28, 2017)
+
+Main:
+- Support including UCX API headers from C++ code
+- UD transport to handle unicast flood on RoCE fabric
+- Compilation fixes for gcc 7.1.1 and clang 3.6
+
+Details:
+- When UD transport is used with RoCE, packets intended for other peers may
+  arrive on different adapters (as a result of unicast flooding).
+- This change adds packet filtering based on destination GIDs. Now the packet
+  is silently dropped, if its destination GID does not match the local GID.
