I have tagged a new release of Thunderdell, the Freemind mindmap to biblatex utilities. Improvements include:

• The ability to emit biblatex or BibTex.
• More consistent/improved Unicode support, particularly in bibliographic keys.
• New feature for requesting either the long or short URL for Wikipedia sources.
• New feature for requesting that only URLs for exclusively online sources be emitted.
• New test for online sources.
• More biblatex fields, such as original publisher and year.
• Faster processing by using lxml, but can still fall back to etree.
• Use of optparse.
• The "essential node" function was removed.
