        When upgrading from a previous release to Zend Framework 1.10 or higher you

            <para>
                Before release 1.10 the <classname>MimeType</classname> validator used a wrong
                naming. For consistency the following constants have been changed:

                When you are translating these messages within your code then use the new constants.
                As benefit you don't need to translate the original string anymore to get a correct
                spelling.

            <title>Self written validators</title>

            <para>
                When setting returning a error from within a self written validator you have to
                call the <methodname>_error()</methodname> method. Before Zend Framework 1.10 you
                were able to call this method without giving a parameter. It used then the first
                found message template.
            </para>

            <para>
                This behaviour is problematic when you have validators with more than one different
                message to be returned. Also when you extend an existing validator you can get
                unexpected results. This could lead to the problem that your user get not the
                message you expected.

                To prevent this problem the <methodname>_error()</methodname> method is no longer

            <para>
                Before Zend Framework 1.10 2 identical messages were thrown within the date
                validator. These were <constant>NOT_YYYY_MM_DD</constant> and
                <constant>FALSEFORMAT</constant>. As of Zend Framework 1.10 only the
                <constant>FALSEFORMAT</constant> message will be returned when the given date
                does not match the set format.

                Before Zend Framework 1.10 the messages within the 2 barcode adapters, the Alpha
                and the Alnum validator were identical. This introduced problems when using custom
                messages, translations or multiple instances of these validators.

            <para>
                As with Zend Framework 1.10 the values of the constants were changed to
                be unique. When you used the constants as proposed in the manual there is
                no change for you. But when you used the content of the constants in your code
                then you will have to change them. The following table shows you the changed values:
