-------------------------------------------------------------------------------
The following list contains only the changes that were done on top
of the original Berkeley UPC version 2.16.0, that is available for
download from the UC Berkeley/LBNL web site:
    http://upc.lbl.gov/download/release/berkeley_upc-2.16.0.tar.gz
	
- Linking with FCA library instead of using dlopen at runtime.

- Fixed an issue using some of MPIs as job spawner (e.g. MPICH2)
  Use MPI_BYTE rather than MPI_CHAR, and use MPI_IN_PLACE.

3. Supported Platforms and Operating Systems
===============================================================================
Summary of changes in the list of supported OSes:

 - Platforms: 
   - x86_64

 - OFED:
   - MLNX_OFED 1.8.5 or higher

4. Known Issues

   does affect various UPC collectives, it does not affect UPC Barrier.
