    <para>
        Lors de la migration d'une version précédente à Zend Framework 1.9.0 vers une version 1.9,
        vous devriez prendre note de ce qui suit.

            <title>MimeType validation</title>

            <para>
                For security reasons we had to turn off the default fallback mechanism of the
                <classname>MimeType</classname>, <classname>ExcludeMimeType</classname>,
                <classname>IsCompressed</classname> and <classname>IsImage</classname> validators.
                This means, that if the <emphasis>fileInfo</emphasis> or
                <emphasis>magicMime</emphasis> extensions can not be found, the validation will
                always fail.
            </para>

            <para>
                If you are in need of validation by using the <acronym>HTTP</acronym> fields which
                are provided by the user then you can turn on this feature by using the
                <methodname>enableHeaderCheck()</methodname> method.

                <para>
                    You should note that relying on the <acronym>HTTP</acronym> fields, which are
                    provided by your user, is a security risk. They can easily be changed and could
                    allow your user to provide a malcious file.

            <para>
                Dans la version 1.9 de Zend Framework, il y a eu un changement dans la manière dont
                <classname>Zend_Http_Client</classname> stocke en interne les informations concernant les

                Ce changement a été mis en place de manière à permettre l'envoi de plusieurs fichiers
                avec le même nom dans le formulaire, en tant que tableau de fichiers. Plus d'informations à

                Comme vous le voyez, ce changement permet l'utilisation du même élément de formulaire avec plusieurs

        <para>
            Prior to the 1.9 release, the menu helper
            (<classname>Zend_View_Helper_Navigation_Menu</classname>) did not
            render sub menus correctly. When the <code>onlyActiveBranch</code>
            was <constant>TRUE</constant> and the option <code>renderParents</code>
            <constant>FALSE</constant>, nothing would be rendered if the deepest active
            page was at a depth lower than the <code>minDepth</code> option.
        </para>

        <para>
            In simpler words; if <code>minDepth</code> was set to <code>1</code>
            and the active page was at one of the first level pages, nothing
            would be rendered, as the following example shows.

            Additionally, users of the 1.9 series may be affected by other changes starting in
            version 1.9.7. These are all security fixes that also have potential backwards
            compatibility implications.

            <para>
                A slight change was made in the 1.9 series to modify the default usage of the Editor
                dijit to use <acronym>div</acronym> tags instead of a <acronym>textarea</acronym>
                tag; the latter usage has <ulink

                implications</ulink>, and usage of <acronym>div</acronym> tags is recommended by the
                Dojo project.
            </para>

            <para>
                In order to still allow graceful degradation, a new <varname>degrade</varname>
                option was added to the view helper; this would allow developers to optionally use a
                <acronym>textarea</acronym> instead. However, this opens applications developed with
                that usage to <acronym>XSS</acronym> vectors. In 1.9.7, we have removed this option.
                Graceful degradation is still supported, however, via a <acronym>noscript</acronym>
                tag that embeds a <acronym>textarea</acronym>. This solution addressess all security
                concerns.
            </para>

            <para>
                The takeaway is that if you were using the <varname>degrade</varname> flag, it will
                simply be ignored at this time.

                Additionally, because the actual mechanism is dealing with character encodings and

                <methodname>setEncoding()</methodname> and <methodname>getEncoding()</methodname>.
                The previous methods <methodname>setCharSet()</methodname> and
                <methodname>setCharSet()</methodname> are now deprecated and proxy to the new
                methods. Finally, instead of using the protected members directly within the
                <methodname>filter()</methodname> method, these members are retrieved by their
                explicit accessors. If you were extending the filter in the past, please check your
                code and unit tests to ensure everything still continues to work.

                the <varname>commentsAllowed</varname> flag no longer has any meaning, and all HTML
                comments, including those containing other HTML tags or nested commments, will be
