This release includes support for a high-speed binary XML storage format, TinyBinary.

The default storage format is still serialized XML. In order to use TinyBinary w/solr, add the following element:
to the Lux updateRequestProcessorChain definition in solrconfig.xml. Note that older versions of Lux cannot read the tiny binary format: once you have stored TinyBinary documents in an index, you must upgrade any Lux clients that connect to it to 0.8 or later.
