`Compatibility <#compatibility>`__

----------------------------------

.. container::

   NSS 3.70 shared libraries are backwards-compatible with all older NSS 3.x shared libraries. A

   program linked with older NSS 3.x shared libraries will work with NSS 3.70 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.
