This update includes a change in the Archive tag. All of the current skins have been updated, but if you have created your own skin, you will need to make a small modification to your templates whenever you used the <mango:Archive> tag. If you don't change your templates, you will see blank archive lists or your category pages will shown wrong headers.
You can see an example of the changes needed in any of the updated skins. Basically, the change is that you need to have an Archive tag enclosing ArchiveProperty tags. Example:
<mango:Archives type="month">
<mango:Archive>
<mango:ArchiveProperty title dateformat="mmmm yyyy" /><br />
</mango:Archive>
</mango:Archives>
