+`Compatibility <#compatibility>`__
+----------------------------------
+
+.. container::
+
+   NSS 3.21.3 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 3.21.3 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.
+
+`Feedback <#feedback>`__
+------------------------
+
+.. container::
+
+   Bugs discovered should be reported by filing a bug report with
+   `bugzilla.mozilla.org <https://bugzilla.mozilla.org/enter_bug.cgi?product=NSS>`__ (product NSS).
