## [Compatibility](#compatibility)

:::{container}
NSS 3.80 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
this new version of the 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.
