Special Notes
~~~~~~~~~~~~~

**Compilation update:** const qualifiers have been removed from
structure fields. This change may generate some compiler errors in your
code and require some minor adjustments.

**Packaging update:** We now offer two packages on Windows for the
following compilers:

*  Visual Studio 2015
*  Visual Studio 2013

Please note, the Visual Studio 2013 package will be discontinued in

We also offer two packages on Linux for the following operating systems
and compilers:

*  CentOS 5.11 using glibc 2.5

The CentOS 5.11 package will be discontinued in HOOPS Exchange 2018
(November 2017).
