* Fri Jan 19 2018
  - Update to 1.2.2
    - Support including UCX API headers from C++ code
    - UD transport to handle unicast flood on RoCE fabric
    - Compilation fixes for gcc 7.1.1, clang 3.6, clang 5
    - 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.
    - Added a new device ID for InfiniBand HCA
* Fri Dec 08 2017
  - Drop doxygen BuildRequires: The documentation was already not
    built with this enabled. Removing the BR causes no regression in
    the package but eliminates a build cycle
    boost -> curl -> doxygen -> openucx -> boost
* Tue Sep 19 2017
  - Rediff openucx-s390x-support.patch as p1 to be in line with
    potential git-generated patches.
