0.10.2 is a maintenance release. Primarily it is about fixing the "endless redirects loop, triggered by a RedCloth exception" bug. Here is the full list of changes in the version:

* Resolved the "endless redirection loop" condition and otherwise improved handling of errors in the rendering engines
* Fixed HTML export
* Upgraded to Rails 0.13.1
* Added layout=no option to the export_html action (it exports page contents processed by the markup engine, but without the default layout - so that they can be wrapped in some other layout)
* <nowiki> tag can span several lines (before it was applied when both opening and closing tags were on the same line only)
* Fixed rendering of Markdown hyperlinks such as [Text](http://something.com/foo)
