NSS 3.65 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 3.65 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.


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


This version of NSS contains a number of contributions for "unsupported platforms". We would like to thank the authors and the reviewers for their contributions to NSS.

Discussions about moving the documentation are still ongoing. (See discussion in the 3.62 release notes.)
