<h2>4.4.1 -- <span style="font-weight: normal;">2021-03-03</span></h2>
<h2> Bug
</h2>
<ul>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-895'>SMACK-895</a>] - BoBIQ#getIQChildElementBuilder throws NPE when the BoB data does not contain ‘max-age’.
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-896'>SMACK-896</a>] - BoBDataExtension is missing getter for BoBData and ContentId
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-897'>SMACK-897</a>] - DirectoryRosterStore.readEntry() should also catch IllegalArgumentException
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-898'>SMACK-898</a>] - AbstractProvider should also consider TypeVariable
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-899'>SMACK-899</a>] - NullPointerException in EntityCapsManager.addCapsExtension
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-900'>SMACK-900</a>] - NPE in DataForm.Builder.addItem()
</li>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-902'>SMACK-902</a>] - DataFormProvider should retrieve the type of fields from &lt;reported/&gt; elements if possible
</li>
</ul>
<h2> Improvement
</h2>
<ul>
<li>[<a href='https://igniterealtime.atlassian.net/browse/SMACK-901'>SMACK-901</a>] - BoBDataExtension.from() should also allow IQs
</li>
