      ciphersuites that use the SHA-256 PRF

      signatures are no longer accepted for OCSP or CRLs, consistent with their handling for general
      certificate signatures.
   -  `Bug 884178 <https://bugzilla.mozilla.org/show_bug.cgi?id=884178>`__ - Add PK11_CipherFinal
      macro

      SSL_HandshakeNegotiatedExtension to be called before the handshake is finished.
   -  `Bug 848384 <https://bugzilla.mozilla.org/show_bug.cgi?id=848384>`__ - Deprecate the SSL
      cipher policy code, as it's no longer relevant. It is no longer necessary to call
      NSS_SetDomesticPolicy because all cipher suites are now allowed by default.

`Compatibility <#compatibility>`__
----------------------------------

.. container::

   NSS 3.15.2 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 3.15.2 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.
