 ### 4.3.3-rc2 Released TBD
 
+* Added a new file, `netcdf_meta.h`.  This file is generated automatically at configure time and contains information related to the capabilities of the netcdf library.  This file may be used by projects dependent upon `netcdf` to make decisions during configuration, based on how the `netcdf` library was built.  The macro `NC_HAVE_META_H` is defined in `netcdf.h`.  Paired with judicious use of `#ifdef`'s, this macro will indicate to developers whether or not the meta-header file is present.  
+    
+    > Determining the presence of `netcdf_meta.h` can also be accomplished by methods common to autotools and cmake-based build systems.

 * Corrected embedded URLs in release notes.
 * Corrected an issue where building with HDF4 support for Visual Studio would fail.
