`New Functionality <#new_functionality>`__
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. container::
- For some certificates, such as root CA certificates that don't embed any constraints, NSS
might impose additional constraints such as name constraints. A new API
(`CERT_GetImposedNameConstraints <http://mxr.mozilla.org/nss/ident?i=CERT_GetImposedNameConstraints>`__) has
been added that allows one to lookup imposed constraints.
- It is possible to override the directory
build system will look for the sqlite library.
.. rubric:: New Functions
:name: new_functions
- *in cert.h*
- **CERT_GetImposedNameConstraints** - Check if any imposed constraints exist for the given
certificate, and if found, return the constraints as encoded certificate extensions.

- The SSL 3 protocol has been disabled by default.
- NSS now more strictly validates TLS extensions and will fail a handshake that contains
- In TLS 1.2 handshakes, NSS advertises support for the SHA512 hash algorithm in order to be
compatible with TLS servers that use certificates with a SHA512 signature (`bug

----------------------------------
.. container::
NSS 3.19 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 3.19 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.
