	    Allows the public_key module to decode and encode RSA and
	    DSA keys encoded using the SubjectPublicKeyInfo format.
	    When pem_entry_encode is called on an RSA or DSA public
	    key type, the key is wrapped in the SubjectPublicKeyInfo
	    format.</p>

          <p>
	    Updated ssl to ignore CA certs that violate the asn1-spec
	    for a certificate, and updated public key asn1 spec to
	    handle inherited DSS-params.</p>

	    Own Id: OTP-7884</p>
        </item>
        <item>
          <p>
	    Changed ssl implementation to retain backwards
	    compatibility for old option {verify, 0} that shall be
	    equivalent to {verify, verify_none}, also separate the
	    cases unknown ca and selfsigned peer cert, and restored
	    return value of deprecated function
	    public_key:pem_to_der/1.</p>

          <p>
	    Better handling of v1 and v2 certificates. V1 and v2
	    certificates does not have any extensions so then
	    validate_extensions should just accept that there are
	    none and not end up in missing_basic_constraints clause.</p>

	    Own Id: OTP-8867</p>
        </item>
        <item>
          <p>
	    Changed the verify fun so that it differentiate between
	    the peer certificate and CA certificates by using
	    valid_peer or valid as the second argument to the verify
	    fun. It may not always be trivial or even possible to
	    know when the peer certificate is reached otherwise.</p>

	    public_key API to make it useful for general use, also

	    Added the functionality so that the verification fun will
	    be called when a certificate is considered valid by the
	    path validation to allow access to each certificate in
	    the path to the user application. Also try to verify
	    subject-AltName, if unable to verify it let the
	    application verify it.</p>

            The documentation is now built with open source tools
            (xsltproc and fop) that exists on most platforms. One
            visible change is that the frames are removed.</p>

            X509 certificate handling has been extended and improved
            as a result of more extensive testing of both the ssl
            and public_key application. Even more extensions of the
            certificate handling is yet to be implemented.</p>
