Sesame 2.6.6
============
Sesame version 2.6.6 fixes over 30 reported issues. Some of the highlights:

 - Several optimizations in query evaluation (especially for queries involving
   subselects and arbitrary-length property paths). 
 - OpenRDF Workbench now auto-detects RDF format for uploads
 - RemoteRepositoryManager now supports complete removal of a server-side
   Repository (including its datadir) 

See the Changelog below for a complete listing of all fixed issues. More
details can be found in the Sesame issue tracker at
