 &#160; It is possible to utilize a custom hook function to alter the tag content htmLawed has finalized (i.e., after it has checked/corrected for required attributes, transformed attributes, lower-cased attribute names, etc.).<br />
 <br />
-&#160; When <span class="term">$config</span>&#160;parameter <span class="term">hook_tag</span>&#160;is set to the name of a function, htmLawed (function <span class="term">hl_tag()</span>) will pass on the element name, and the <em>finalized</em>&#160;attribute name-value pairs as array elements to the function. The function is expected to return the full opening tag string like <span class="term">&lt;element_name attribute_1_name="attribute_1_value"...&gt;</span>&#160;(for empty elements like <span class="term">img</span>&#160;and <span class="term">input</span>, the element-closing slash <span class="term">/</span>&#160;should also be included).<br />
+&#160; When <span class="term">$config</span>&#160;parameter <span class="term">hook_tag</span>&#160;is set to the name of a function, htmLawed (function <span class="term">hl_tag()</span>) will pass on the element name, and, in the case of an opening tag, the <em>finalized</em>&#160;attribute name-value pairs as array elements to the function. The function, after completing a task such as filtering or tag transformation, will typically return an empty string, the full opening tag string like <span class="term">&lt;element_name attribute_1_name="attribute_1_value"...&gt;</span>&#160;(for empty elements like <span class="term">img</span>&#160;and <span class="term">input</span>, the element-closing slash <span class="term">/</span>&#160;should also be included), etc.<br />
+<br />
+&#160; Any <span class="term">hook_tag</span>&#160;function, since htmLawed version 1.1.11, also receives names of elements in closing tags, such as <span class="term">a</span>&#160;in the closing <span class="term">&lt;/a&gt;</span>&#160;tag of the element <span class="term">&lt;a href="http&#58;//cnn.com"&gt;CNN&lt;/a&gt;</span>. Unlike for opening tags, no other value (i.e., the attribute name-value array) is passed to the function since a closing tag contains only element names. Typically, the function will return an empty string or a full closing tag (like <span class="term">&lt;/a&gt;</span>).<br />
 <br />
 &#160; This is a <strong>powerful functionality</strong>&#160;that can be exploited for various objectives: consolidate-and-convert inline <span class="term">style</span>&#160;attributes to <span class="term">class</span>, convert <span class="term">embed</span>&#160;elements to <span class="term">object</span>, permit only one <span class="term">caption</span>&#160;element in a <span class="term">table</span>&#160;element, disallow embedding of certain types of media, <strong>inject HTML</strong>, use <a href="http://csstidy.sourceforge.net">CSSTidy</a>&#160;to sanitize <span class="term">style</span>&#160;attribute values, etc.<br />
 <br />
 &#160; As an example, the custom hook code below can be used to force a series of specifically ordered <span class="term">id</span>&#160;attributes on all elements, and a specific <span class="term">param</span>&#160;element inside all <span class="term">object</span>&#160;elements:<br />

 &#160; Upgrading is as simple as replacing the previous version of <span class="term">htmLawed.php</span>&#160;(assuming it was not modified for customized features). As htmLawed output is almost always used in static documents, upgrading should not affect old, finalized content.<br />
 <br />
+&#160; <strong>Important</strong>&#160; The following upgrades may affect the functionality of a specific htmLawed as indicated by their corresponding notes:<br />
+<br />
+&#160; (1) From version 1.1-1.1.10 to 1.1.11, if a <span class="term">hook_tag</span>&#160;function is in use: In version 1.1.11, elements in closing tags (and not just the opening tags) are also passed to the function. There are no attribute names/values to pass, so a <span class="term">hook_tag</span>&#160;function receives only the element name. The <span class="term">hook_tag</span>&#160;function therefore may have to be edited. See <a href="#s3.4.9">section 3.4.9</a>.<br />

+  Permitting the '*style*' attribute brings in risks of `click-jacking`, `phishing`, web-page overlays, etc., `even` when the 'safe' parameter is enabled (see section:- #3.6). Except for URLs and a few other things like CSS dynamic expressions, htmLawed currently does not check every CSS style property. It does provide ways for the code-developer implementing htmLawed to do such checks through htmLawed's '$spec' argument, and through the 'hook_tag' parameter (see section:- #3.4.8 for more). Disallowing 'style' completely and relying on CSS classes and stylesheet files is recommended.

-  When '$config' parameter 'hook_tag' is set to the name of a function, htmLawed (function 'hl_tag()') will pass on the element name, and the `finalized` attribute name-value pairs as array elements to the function.

   htmLawed allows an admin to use '$config["safe"]' to auto-adjust multiple '$config' parameters (such as 'elements' which declares the allowed element-set), which otherwise would have to be manually set. The relevant parameters are indicated by '"' in section:- #2.2). Thus, one can pass the '$config' argument with a simpler value.

   Upgrading is as simple as replacing the previous version of 'htmLawed.php' (assuming it was not modified for customized features). As htmLawed output is almost always used in static documents, upgrading should not affect old, finalized content.
 
+  *Important*  The following upgrades may affect the functionality of a specific htmLawed as indicated by their corresponding notes:
+
+  (1) From version 1.1-1.1.10 to 1.1.11, if a 'hook_tag' function is in use: In version 1.1.11, elements in closing tags (and not just the opening tags) are also passed to the function. There are no attribute names/values to pass, so a 'hook_tag' function receives only the element name. The 'hook_tag' function therefore may have to be edited. See section:- #3.4.9.

   Old versions of htmLawed may be available online. E.g., for version 1.0, check http://www.bioinformatics.org/phplabware/downloads/htmLawed1.zip, for 1.1.1, htmLawed111.zip, and for 1.1.10, htmLawed1110.zip.
