Compatibility

NSS 3.54 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 3.54 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

Bugs discovered should be reported by filing a bug report with bugzilla.mozilla.org (product NSS).
