There have been the usual round of bug fixes and enhancements, but the main news with this release is the inclusion of support for SolrCloud. You can now store and search XML documents in a distributed index using Lux with SolrCloud. The implementation is still preliminary, not having seen wide testing, but I encourage folks to try it out!
