Post excerpts ({{post_excerpt}} placeholder) are no longer enclosed between <p> and </p> tags. (@D.O.)
Please note that, if you're upgrading from previous versions of the plugin, you may have to edit your template or component (if your styles are affected, you just have to change {{post_excerpt}} to <p>{{post_excerpt}}</p>)
update: 0.9.2.1 - bugfix release
