Bugs fixed in NSS 3.65


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).


Due to some changes in the Firefox release cycle, NSS 3.67 has yet to be added to the NSS release schedule (3.66 is not affected). I will announce the date to this list once defined.

Best, Benjamin
