`Compatibility <#compatibility>`__
----------------------------------

.. container::

   NSS 3.19.2.2 shared libraries are backward compatible with all older NSS 3.x shared libraries. A
   program linked with older NSS 3.x shared libraries will work with NSS 3.19.2.2 shared libraries
   without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs
   to the functions listed in NSS Public Functions will remain compatible with future versions of
   the NSS shared libraries.
