NSS version 3.28, 3.28.1, 3.28.2 and 3.29 contained changes that were in violation with the NSS
compatibility promise.
ECParams, which is part of the public API of the freebl/softokn parts of NSS, had been changed to
include an additional attribute. That size increase caused crashes or malfunctioning with
applications that use that data structure directly, or indirectly through ECPublicKey,
ECPrivateKey, NSSLOWKEYPublicKey, NSSLOWKEYPrivateKey, or potentially other data structures that
reference ECParams. The change has been reverted to the original state in `bug
SECKEYECPublicKey had been extended with a new attribute, named "encoding". If an application
passed type SECKEYECPublicKey to NSS (as part of SECKEYPublicKey), the NSS library read the
uninitialized attribute. With this NSS release SECKEYECPublicKey.encoding is deprecated. NSS no
longer reads the attribute, and will always set it to ECPoint_Undefined. See `bug
Note that NSS 3.28.3 from the older NSS 3.28.x branch
:ref:`mozilla_projects_nss_nss_3_28_3_release_notes` with the identical fixes.
`Compatibility <#compatibility>`__
----------------------------------
.. container::
NSS 3.29.1 shared libraries are backward compatible with most older NSS 3.x shared libraries, but
depending on your application, may be incompatible, if you application has been compiled against
header files of versions 3.28, 3.28.1, 3.28.2 NSS 3.29.1.
A program linked with most older NSS 3.x shared libraries (excluding the exceptions mentioned
above), will work with NSS 3.29.1 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.
If you had compiled your application against header files of NSS 3.28, NSS 3.28.1, NSS 3.28.2 or
NSS 3.29, it is recommended that you recompile your application against NSS 3.29.1 (or NSS
3.28.3), at the time you upgrade to NSS 3.29.1 (or NSS 3.28.3).
