If downloaded, you may notice that Microformats are still not supported… my bad. It’s on my to-add list, including language localization. So that will probably be the focus of the next release, although I can’t say for sure when that will be.
UPGRADING NOTE: If you are upgrading from the previous version of WP Contact Manager then all you have to do is upload the new theme and add one more custom field through the Custom Write Panel plugin: Title. More detailed instructions are included on the WP Contact Manager page.
