- When using the Makefiles, NSS can be built in parallel, speeding up those builds to more
similar performance as the build.sh/ninja/gyp system. (`Bug

- Algorithms marked as deprecated will ultimately be removed.
- Several root certificates in the Mozilla program now set the CKA_NSS_SERVER_DISTRUST_AFTER

`Compatibility <#compatibility>`__
----------------------------------
.. container::
NSS 3.53 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 3.53 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.
