Sesame 2.8.0
=============

Sesame 2.8.0 addresses 66 issues, including several major new features. Some of
the highlights:

- RDF 1.1 support, including updates to all parsers and writers.
- An extension to SPARQL Protocol to support full Transaction Isolation over HTTP 
- Configurable transaction isolation levels in the Repository API
- The LuceneSail, a configurable SAIL implementation for fast string-based search in 
  RDF datasets with long literals.
- Multiple utility and convenience improvements in the Model and Repository APIs

In addition to these and other new features, a substantial amount of bugs have been
fixed in various areas of the framework, including the SPARQL engine,
transaction handling, and parsing. 

Users upgrading from older versions of Sesame are **strongly encouraged** to
