New Functionality
No new functionality is introduced in this release. This is a patch release to fix a bug that caused NSS to accept forged RSA signatures.
A new symbol, _SGN_VerifyPKCS1DigestInfo is exported in this release. As with all exported NSS symbols that have a leading underscore '_', this is an internal symbol for NSS use only. Applications that use or depend on these symbols can and will break in future NSS releases.

Compatibility
NSS 3.16.2.1 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 3.16.2.1 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.
